Cloth face coverings are no substitute for actual masks, but may be better than nothing. Let me show you a few studies. This study testing the efficacy of various homemade masks found that scarves, pillowcases, and 100 percent cotton t-shirts were probably the most suitable household materials, blocking various bacteria and viruses about 60 percent as well as surgical masks. As you can see the average filtration efficiency was about 90% or more with surgical masks, compared to more like 50, 60, or 70 percent for the improvised fabrics. Vacuum cleaner bags worked better, right up there alongside surgical masks, but were considerably harder to breathe through, “rendering it unsuitable for a face mask.” The same with the tea towel.

Engineers at the University of Cambridge looked at 20 different options, compared to surgical masks. So, you can see, for example, that lightweight T-shirts have less than half the filtration of heavyweight cotton tees. As you can see, windbreakers and denim jeans are right up there, comparable to surgical masks, alongside the vacuum cleaner bags, but suffer the same problem. They’re “very difficult to breathe through…and are thus ill-suited for face mask construction.” Taking that balance between breathing and filtration into account, the most suitable fabrics for face mask construction may include something like cotton flannel, though in a pinch a single sock pressed tight against the nose and mouth might make a good emergency mask substitute. Regardless of which you use, try not to touch the front of mask while you’re wearing it or when you remove it, then wash your hands. And cloth face coverings should be washed regularly.

Even though face coverings are intended to protect others from the wearer rather than the wearer from others, masks have been recommended for self-protection during the last pandemic for those at high risk in unavoidably crowded settings. In hospital settings, for example, mask wearers appeared to have been comparatively protected from contracting SARS. However, even three or four layers of cloth (in the form of cotton handkerchiefs) only filters a fraction of what a simple surgical mask can block. These are penetration numbers; so, four layers of cotton may only block 4%, 10 times less than a simple surgical mask.

Improvised masks didn’t seem to help in 1918, attributed to the fact that, to get the necessary protective filtration, so many layers of gauze had to be used that breathing was difficult and air leaked around the edges. An improvised face mask should be viewed as the last possible alternative if a supply of commercial face masks is not available.

The World Health Organization still doesn’t think routine mask-wearing in public is necessary, expressing concern that it might lead to a false sense of security and neglect of more important measures such as hand hygiene and social distancing, and may lead to touching one’s face. On the other hand, one could imagine how wearing a mask might prompt people to avoid touching their face. Gloves could play a similar role. Seeing bright purple gloves on your hands can serve as a constant reminder. Here’s me recording the audiobook to How to Survive a Pandemic. Yes, you can still breathe in virus while wearing a mask, and you can still contaminate yourself with gloved fingers, but anything that keeps you constantly conscious about the position of your hands and stops you from touching your face might help.

Speaking of self-conscious, if everyone wore masks in public, symptomatic patients who definitely should be wearing them wouldn’t fear being singled out for stigma. Of course, universal use of face masks in public during a pandemic could only be considered if supplies permit. Sadly, inadequate preparation, misuse, and hoarding have led to a critical shortage of personal protective gear for those on the front line. That’s why the CDC is recommending “cloth face coverings” instead of surgical masks.

You know things are getting desperate when an editorial in the Journal of the American Medical Association entitled “Sourcing Personal Protective Equipment During the COVID-19 Pandemic” includes as a proposed suggestion … “coffee filter masks.”

Surgical masks are usually made out of paper with a gelatinous layer and should be changed every four hours or when they become wet with saliva or other fluid, whichever comes first. Surgical masks, as the name implies, are typically meant to protect others (as in the patient opened up on the operating table). N95 masks, or N95 “respirators” as they’re often called, are the cup-like masks that fit tighter to the face. They are intended to protect the wearer. The WHO and CDC have conflicting guidelines as to what healthcare workers should wear during routine care of patients with COVID-19. The CDC, along with its European counterpart, recommends N95 respirators, whereas the WHO suggests surgical masks are sufficient. While part of the WHO’s reluctance to endorse N95s may be out of a sensitivity to the global scarcity of such resources, the underlying transmission dynamics of the COVID-19 virus remain largely unknown; so, it’s impossible at this time to say which recommendation is right with any certainty.

The relative importance of direct respiratory spread for COVID-19 versus indirect contact via contaminated objects is unclear. For other viral respiratory illnesses like the common cold, breathing appears more important than touching. That’s what that arm brace study showed. For example, in one rhinovirus experiment, only 50 percent of those touching contaminated coffee cup handles became infected. For the flu, the relative importance of transmission continues to be debated, which is remarkable since we’ve known about the virus for nearly a century.

Note that N95 respirators only work at peak efficiency if they conform completely to the face; so, they aren’t for everyone. Even one to two days of stubble may significantly undermine the necessary seal. This is an actual infographic from the CDC showing which types of facial hair may or may not be suitable.

They also must be used properly. In a laboratory setting, N95 respirators have been found to be very effective, but out in the real world, a review of the best science on preventing the spread of respiratory viruses found “no evidence that the more expensive, irritating and uncomfortable N95 respirators were superior to simple surgical masks.” Not that N95s aren’t better at filtration, but perhaps due to poor compliance. I remember how uncomfortable they were when I was working with tuberculosis patients. So, that would support the WHO recommendation that N95s aren’t necessarily better in real world settings, though with proper fitting and compliance they’d presumably come out on top.

Even with the perfect mask sealed over your mouth and nose, your eyes are still exposed, leading to a suggestion that medical workers wear goggles. Monkeys can apparently be infected by dripping the COVID-19 virus into their eyes, but a retrospective study of SARS, at least, found no documented cases of transmission to healthcare workers just because they didn’t use eye protection.

Until we know more about the transmission of this virus, it would seem prudent for those in close contact with coughing patients to err on the side of caution and use both eye protection (like at least a face shield) and N95 respirators. During the SARS outbreak in North America, regular surgical masks were initially recommended, but the advice switched to respirators after doctors started dying.

Here’s how N95 masks compare to various cloth face coverings. Note these are graphs of penetration, so you can see for an N95 mask there’s less than 5% penetration. So, at the particle size at which an N95 mask blocks more than 95%, a mask made out of a t-shirt blocks only about 10%, scarves about 20%, sweatshirts about 30%, and towels closer to 40%.      

It’s interesting that the Hanes t-shirts are no better than any of the other t-shirts, but the Hanes sweatshirts appeared to have an edge for some reason. Of course, the study was funded by Hanes—just kidding.

  1. Darwin Galt,
    The Goya bean company is just a cover name for a commune group of hippies in the Seatle area. Move the Goya letters around a bit and you get y o g a, a dead ringer for a group of hippies trying to push better health and saying stupid things like, 1. Eating beans improves insulin sensitivity and, 2. Lowers blood pressure, 3. Improves G.I. tract health, 4. Reduces cancer and 5. Makes rainbows pop up all over the sky with multi-colored free beans raining down. Is this a conspiracy? I think so. Hey, that reduced pricing sounds great. I’m going to get me a few cases.

    1. Goya has never been owned by hippies or out of Washington state.

      Between 2014 and 2016 Goya opened five new facilities including manufacturing and distribution centers located in New Jersey, Texas, California, and Georgia to meet rising consumer demand. Currently, Goya Foods is headquartered on a 40-acre lot in Jersey City, New Jersey. Goya also operates a manufacturing facility in San Cristóbal, Dominican Republic, and a distribution center in Bayamón, Puerto Rico.

      Robert Unanue descendant of the original founder heads the company.

    2. Dan C, You really are good at the letter shuffling game, as YR pointed out the other day! I never thought of Goya being shuffled to yoga.

      Beans are second only to whole grains regarding over all health! See the link and summary below:

      https://academic.oup.com/ajcn/article/105/6/1462/4569801

      The food group with the highest Risk Reduction was Whole Grains! The more you eat, the less likely you will succumb to a chronic disease and die early. Beans were next on the list.

      Figure 2 on page 5 of the research paper shows an excellent graph of the risk ratios of each food group.

      ABSTRACT
      Background: Suboptimal diet is one of the most important factors
      in preventing early death and disability worldwide.

      Objective: The aim of this meta-analysis was to synthesize the
      knowledge about the relation between intake of 12 major food
      groups, including whole grains, refined grains, vegetables, fruits,
      nuts, legumes, eggs, dairy, fish, red meat, processed meat, and
      sugar-sweetened beverages, with risk of all-cause mortality.

      Conclusion: Selecting specific optimal intakes of the investigated
      food groups can lead to a considerable change in the risk of premature
      death. Am J Clin Nutr 2017;105:1462–73.

      But we better keep this fact quiet, otherwise, we’ll get John Newell all riled up ;-)

      1. DG & RB,
        I can’t wait to try some Yoga beans! Actually, I thought beans out ranked grains. I eat both in large quantities.

  2. Barb,
    The Dr. Fair story sounds crazy. He didn’t want to go on a ventilator so he said, just increase my oxygen.This way he remained responsive and communicated with staff. Well, like, duh, doesn’t that make some sense. What doesn’t make sense is a doctor gets on a sardine plane to LA and claims the virus must have come in through his eyes.

    1. Yes Dan, exactly what I was thinking. The very LAST place I would want to be right now is on a plane or cruise ship etc. The other thing is about the testing, and how many people are walking around with confidence in ‘inaccurate’ test results?

    2. Eggplant is a good medical model for the pulmons of COVID-19 patients. Cut an eggplant in half and you will understand why oxygenotherapy is not a good thing for COVID-19 treatment.

  3. Okay, after watching this video again I got to the “only 50% of the people touching the infected coffee cup handles became infected” and that is a helpful statistic to me with regards to touching things.

  4. So it seems that the great majority of masks you see people wearing aren’t very effective. More for show and being polite, I guess. And thus the much more important factors are keeping a social distance (yea, I hate that term), not touching your face, and washing your hands a lot.

    1. Chuck R.

      The states in the USA that mandated mask-wearing have a lower transmission of COVID-19 and the states that did not mandate mask-wearing have a higher transmission rate of COVID-19.

      Airplanes would be another example. This pandemic, there have been people who have become infected on an airplane, but the most recent one, 3 people became infected. Compare that to years past. One influenza year, having one person with the flu, 72 people became infected on the flight. With SARS-1, having 1 person infected, 22 or 24 people became infected on the flight.

      This year, people on flights are required to wear masks and 3 people become infected on a flight isn’t so bad at all.

      We know that there is a huge COVID-19 problem in air travel because over 1000 TSA people have tested positive, so it is in the airports.

      We will see soon if it really is only 3 people that became infected on that flight or if some show up a few weeks from now, but masks might be seriously affective if the 3 is accurate.

      1. With over 1000 TSA agents testing positive, I really would have expected there to be several news reports of COVID-19 being spread through the air travel by now. I think the masks have been super-effective.

    2. Chuck R,

      It appears that distancing is perhaps most important. As has been said by several: The virus can’t get you if it can’t get TO you. So, distance, distance, distance.

      And I don’t think of it as “social” distance, but rather real physical distancing. I think of “social distancing” as what people do when they become unhappy with aspects of another person or group, such as with their behavior, ideas, attitudes, comments, etc. A social withdrawal, if you will.

      That said, masks appear to reduce the risk, because another important factor in becoming infected is how much virus a person is exposed to — the viral “dose,” if you will. And masks probably reduce that, though not to zero, and maybe not by much. But certainly by something. And if they may reduce exposure to below the required dose. But they should always be a part of distancing, and hand washing.

      Actually, masks appear to be more effective than a lot of drugs we take. And a lot of treatments for cancer. Because many to most of these drugs or treatments are not really effective for most people who take them, or are subjected to them.

        1. Here is a group of scientists who are highly pro-mask wearing and their point is that the researchers who studied masks were asking the wrong questions and were coming to the wrong conclusions. They STRONGLY disagree with the anti-mask community and they also point out things like high-quality studies are immoral to do because you can’t force people to not wear masks.

          https://theconversation.com/masks-help-stop-the-spread-of-coronavirus-the-science-is-simple-and-im-one-of-100-experts-urging-governors-to-require-public-mask-wearing-138507

          This part is one of the key parts:

          I think there were three key problems.

          The first was that most researchers were looking at the wrong question – how well a mask protects the wearer from infection and not how well a mask prevents an infected person from spreading the virus. Masks function very differently as personal protective equipment (PPE) versus source control.

          Masks are very good at blocking larger droplets and not nearly as good at blocking tiny particles. When a person expels droplets into the air, they quickly evaporate and shrink to become tiny airborne particles called droplet nuclei. These are extremely hard to remove from the air. However, in the moist atmosphere between a person’s mouth and their mask, it takes nearly a hundred times as long for a droplet to evaporate and shrink into a droplet nuclei.

          This means that nearly any kind of simple cloth mask is great for source control. The mask creates humidity, this humidity prevents virus-containing droplets from turning into droplet nuclei, and this allows the fabric of the mask to block the droplets.

          Unfortunately, nearly all of the research that was available at the start of this pandemic focused on mask efficacy as PPE. This measure is very important for protecting health care workers, but does not capture their value as source control. On Feb. 29, the U.S. surgeon general tweeted that masks “are NOT effective in preventing general public from catching #Coronavirus.” This missed the key point: They are extremely effective at preventing its spread, as our review of the literature showed.

          The second problem was that most medical researchers are used to judging interventions on the basis of randomized controlled trials. These are the foundation of evidence based medicine. However, it is impossible and unethical to test mask-wearing, hand-washing or social distancing during a pandemic.

          Experts like Trisha Greenhalgh, the author of the best-selling textbook “How to Read a Paper: The Basics of Evidence Based Healthcare,” are now asking, “Is Covid-19 evidence-based medicine’s nemesis?” She and others are suggesting that when a simple experiment finds evidence to support an intervention and that intervention has a limited downside, policymakers should act before a randomized trial is done.

          Results of mask-wearing
          There are numerous studies that suggest if 80% of people wear a mask in public, then COVID-19 transmission could be halted. Until a vaccine or a cure for COVID-19 is discovered, cloth face masks might be the most important tool we currently have to fight the pandemic.

          Given all of the laboratory and epidemiological evidence, the low cost of wearing masks – which can be made at home with no tools – and the potential to slow COVID-19 transmission with widescale use, policymakers should ensure that everyone wears a mask in public.

          1. This article is an example of practical science winning the debate over researchers doing studies.

            I think Pritikin would have liked them.

    3. In some ways, masks seem to be just as effective as, or more effective than, many pharmaceutical drugs and hospital treatments. They also have far fewer side effects and their purchase is less likely to lead to bankruptcy.

      If we look at the number of patients that need to be treated to prevent one adverse event with many common drugs, eg 88 in this example below,
      http://www.polypharmacy.scot.nhs.uk/polypharmacy-guidance-medicines-review/for-healthcare-professionals/effectiveness-nnt/by-medicine/ace-in
      and then consider the reported effectiveness of masks in blocking, the virus, mask-wearing appears relatively effective
      https://www.pnas.org/content/117/26/14857

    4. It’s just a mask. COME ON GUYS! Just do what you’re told, and don’t ask any questions.
      https://www.youtube.com/watch?v=zXUtsft0Z74&feature=youtu.be
      How many of us have been duped into deciding what mask to use, instead of discovering the real face behind the mask?
      Welcome to China! I hope you enjoy a land where from now on the government tells you if you can go to work or school and whom you can see and whom you cannot, which kind of stores you can shop in and how close you can get to another person. A government that regulates the air you breathe, the news you are allowed to hear. the ground you walk on and your toilet paper.
      Good by to the land of the free and the home of the statue of LIBERTY.
      Trump will take the statue of Liberty with him to his grave when He is assassinated. At least he will have more freedom there than they gave him to lead the country.

      1. ‘ A government that regulates the air you breathe,’

        If you truly think that’s a bad thing, then I suggest that you seek an urgent mental health assessment.

        1. Mr Fumble . . ., I live way out in the country on several acres of land. I am used to having my windows open 24-7 all year. I spend much of the day outside. I never get a cold or flu because I understand the needs of healthy gut, which are vegan diet, plenty of exercise and REGULAR EXPOSURE TO CHALLENGING MICROBES. Much of my life my job has been working with sick people. Now the government is trying to force me to “protect” myself from the very things that have kept my immune system strong for 70 years. This is the way they treat people in China and North Korea, but in the US nobody understands that they are being “protected” from the very things that keep them safe and free.The ATF can raid your home church or business, confiscate your computers, freeze your bank accounts and seize your herbs for the “crime” of selling natural, herbal immune boosters.
          They will allow nothing that will set you free from government control. Enjoy!

            1. Mr Fumblefingers,
              I am not saying it is bad for the government to protect us from pollution, but their regulations should end where my nose begins. If a woman has a right over her own body, shouldn’t I have a right to breathe fresh air freely without having to have a mask over my nose and mouth? This is supposed to be a free country, But even the government control of pollution is quite mixed up in some ways I fully agree that dangerous pollutants in smoke from factories need to be prevented from polluting the air. CO2 is not a dangerous chemical or you would do well to quit producing it, maybe that is what the masks are for ;). Plants need CO2 to grow, and that is where ALL the food on our tables comes from. We are told that methane is a greenhouse gas 86 times more potent than CO2. Cattle are put out very high amounts of this super potent greenhouse gas, which neither humans nor plants need to breathe. If the government would ban the dairy and beef industry, like they are trying to ban the coal industry, The green house gas problem would be essentially solved..

      2. Marcy,

        You seem so angry and scared. I watched the spooky clown but didn’t figure out what the message was.

        To me, the message was that people are afraid that some scary government is going to try to control them.

        Is that what it is? Is it that a government is going to come and force you to wear a mask or get vaccinated or something?

        I am so busy trying to save the lives of all of my elderly relatives and my brother who was diagnosed with cancer and grieving the young people around me who died from COVID-19 that I am out of touch with that perspective.

        1. To me, the clown is trying to manipulate people into getting scared.

          I wonder how much money that man gets from clicks on his internet channel.

          Patch Adams has a much nicer personality clown and he could use some clicks.

        2. Deb,
          No, I am not scared or angry. It is the government and the violent mobs who are angry and scared that we had too good of economy to get the present administration out of the white house. Those who hate your freedom are the ones that want to get you so scared that you will not question their forcing you to wear a mask. I am not scared. No government will force me to cower behind a mask. If I have to wear a mask to shop at Walmart no one can scare me into wearing one to shop there, There are many other stores I can shop at that do not make me hide behind a mask. I will not am not sick, so why do I need to protect others from me? Why do I need to contribute to big corporate businesses while the little mom and pop stores are shuttered to drive them out of business? I live in America, the land of the free and the home of the brave. When the present Administration gets out of office, they will take the statue of liberty with them, because the new administration will not need it any more. They would demolish it with all the other memorials of our history they are throwing down. But I know their oppression will not last long, as God Himself will take it out and restore my freedom.

  5. There are a lot of masks on Amazon that are infused with copper and zinc or silver ions and I have seen the same things on the shopping channels.

    I have seen ones with 6-layers infused with zinc on some layers and copper on other layers. The one I was just looking at cost $22, which is too much, but having a few high-quality masks probably makes sense.

    For gamblers, there are a few Kickstarters with masks that have Hepa filters and fans – yes real air purifier masks. One is $119 on indiegogo which is a crowdfunding site that doesn’t guarantee you will get one.

    But if that is the future of masks, it might be an excellent type of design for people who have to wear masks 8 hours + a day.

    That type of design has already been marketed to an Asian market and if I did have to wear masks all day, that would be what I would want.

    I don’t have to wear them all day and that is expensive but what I do know is that people who do wear masks all day, pull them down to breathe through their nose frequently throughout the day. I have stood in line at the bank and watched every teller and half of the people in line do that.

    I think it becomes we need technology to come in and design better masks and it is happening. Next, the competition has to come in to bring the prices down.

      1. What the American Lung Association doesn’t talk about is how much the viral load is increased for patients wearing a source control mask.

    1. Any surgeon or ACTUAL ASTHMA patient can safely say you anti-mask loons are just that. Why? Surgeons wear masks for hours during complex surgery with no O2 problems AT ALL. And asthmatics are COMMONLY told by their doctor to wear a N95 mask during bad air days TO HELP THEIR CONDITION.

      1. Not true at all – mask actually can promote infection. Anti masks “loons” are informed by evidence, not fear and crap studies.
        From a early as 1981, researchers have concluded wearing of a mask had little relevance on infection rates in the operating room https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2493952/pdf/annrcse01509-0009.pdf A 2016 cochrane review of mask use during clean surgical procedures studied three trials, involving a total of 2106 participants. There was no statistically significant difference in infection rates between the masked and unmasked group in any of the trials. the Authors noted “facemasks themselves may actually serve as a source of to contaminate the surgical wound, e.g. by incorrect wear or by leaking air from the side of the mask due to poor string tension. “” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7138271/
        this one? https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD012653.pub2/full?highlightAbstract=infection%7Cpreventing%7Cdispos%7Cin%7Cfor%7Cmasks%7Cclean%7Cwinded%7Cdisposable%7Csurgeri%7Cprevent%7Cdisposabl%7Cwound%7Cface%7Csurgic%7Cfour%7Csurgical%7Cwind%7Csurgery%7Cinfect%7Cmask

        And asthma? Adding a mask to a condition of Increased airway resistance is a bad idea ( 2 Chinese boys have died in China during gym class wearing N95s prompting the Chinese Government to ban mask use during physical activity) and masks are associated with INCREASED respiratory infections which is exactly what asthmatics dont want. The only randomized controlled trial (RCT) conducted on cloth face masks (involving 1,607 hospital healthcare workers at 14 hospitals) for healthcare workers found cloth masks posed a 13% increased risk of Influenza-Like Illness infection to those wearing them. The study authors note “moisture retention, reuse of cloth masks, and poor filtration may result in an increased risk of infection.”
        – The same RCT found particle penetration of cloth masks was almost 97%.

            1. Deb, If a governor tells you that it is safe to protest, riot and loot, burning police cars in a peaceful march, but it is dangerous to go to church or attend a Trump presidential rally, I would not trust Him when he tells me I have to wear a mask to be safe. No mask is safe, because it is for the purpose of controlling our lives and concealing our real feelings and emotions from others. Masks are for bank robbers and thieves.Since masks are associated with people who have evil intentions, subconsciously, when we see s stranger in a mask, we fear him, no matter how nice he is. Can’t you see that this is the agenda behind this control of everyone? They even announced on the news that they were trying to instill enough fear in people that they would want to stay inside their homes isolated from society. Fear and isolation is a sure recipe for a greatly weakened immune system.

              1. Marcy,

                I do know that there are a lot of politics going on but I can use church as an example that several of the biggest spikes traced back to singing at church. There was a pastor who defied a lockdown and he died from COVID.

                I am someone who would call just about every side out for politics and I also enjoyed listening to Trump the first months of this. So I am not someone who will use this virus for political purposes or against religion.

                My friends were doing zoom churches and YouTube churches and some of them are back to church but the study with the choir is why churches are facing scrutiny.

                Cruise ships are also facing scrutiny because of the same thing.

                Well, God bless you and keep you.

                But the mask science is different than what the press or YouTube does with it.

        1. Dr. Scott Atlas interview from this morning on Opening Schools – http://video.foxnews.com/v/6171829059001/

          Masks – 10 RCTs that reported estimates of the effectiveness of face masks in reducing laboratory-confirmed influenza virus infections in the community from literature published during 1946–July 27, 2018. In pooled analysis, we found no significant reduction in influenza transmission with the use of face masks (RR 0.78, 95% CI 0.51–1.20; I2 = 30%, p = 0.25) . One study evaluated the use of masks among pilgrims from Australia during the Hajj pilgrimage and reported no major difference in the risk for laboratory-confirmed influenza virus infection in the control or mask group. Two studies in university settings assessed the effectiveness of face masks for primary protection by monitoring the incidence of laboratory-confirmed influenza among student hall residents for 5 months. The overall reduction in ILI or laboratory-confirmed influenza cases in the face mask group was not significant in either studies. Study designs in the 7 household studies were slightly different: 1 study provided face masks and P2 respirators for household contacts only, another study evaluated face mask use as a source control for infected persons only, and the remaining studies provided masks for the infected persons as well as their close contacts . None of the household studies reported a significant reduction in secondary laboratory-confirmed influenza virus infections in the face mask group

          COVID-19 Tests Are Worthless?

          COVID-19 test results that are testing for the full family of coronaviruses? I kid you not. “A positive test result shows you may have antibodies from an infection with the virus that causes COVID-19. However, there is a chance a positive result means that you have antibodies from an infection with a virus from the same family of viruses (called coronaviruses), such as the one that causes the common cold.,” says the CDC on its website

          Why Masks Do More Harm Than Good – https://vimeo.com/424254660

            1. I laughed when I read the anecdote of a man who disputed the concept of wearing masks way back then and he died after being exposed to patients without masks.

              https://en.m.wikipedia.org/wiki/Manchurian_plague

              The debate started right at the beginning.

              My coworker has debated masks during COVID and the people against masks died weeks later and no, they weren’t even 60 years old.

        2. Alright, I went to the one where you said “this one” and scrolled endlessly down to see the face mask answer and it said:

          “Due to clinical heterogeneity, the review did not pool data.”

          1. oh and Deb would like to share the great evidence to support masking? Careful, my sister did a PHd on this issue so I know the evidence inside and out…Be assured, it is of the lowest quality you can find, “expert opinion etc” The June 5 WHO guideline (pg 7-8) discusses the benefits and risks of universal masking. The guideline lists numerous risks of healthy people wearing masks, but sparse benefits other than “reduced potential exposure risk.” and ridiculous notions like “creates employment” The language also indicates the benefit of universal cloth masking is to collect data and that universal masking is an experiment. If this is indeed an experiment, under international law of the Nuremberg/Helskini agreement, consent must be voluntary and study participants must give permission. This is impossible with mandatory policy.

            Want some good studies?
            A May 2020 meta-analysis by Xiao et al. published in the CDC Journal Emerging Infectious Diseases examined studies from 1946-2018 to assess Measures for Pandemic Influenza in Non-healthcare Settings.They found: “Our systematic review found no significant effect of face masks on transmission of laboratory-confirmed influenza.”
            The review included cloth masks and found,: “There are still few uncertainties in the practice of face mask use, such as who should wear the mask and how long it should be used for.”
            They went on to conclude: “Compliance in uninfected close contacts could be a problem” and “Proper use of face masks is essential because improper use might increase the risk for transmission.”
            · b) A May 2020 systematic review by Perski et al. found the evidence from RCTs to be equivocal as to whether or not wearing face masks in community settings resulted in a reduction in clinically- or laboratory-confirmed viral respiratory infections. However, the authors also confirmed that contamination was a risk from the improper use of masks.
            c) Several trials of masks in community settings, including two 2011 systematic reviews found masks were not effective in reducing infection rates. And a 2015 systematic review and Scientific advice to the UK government also found inconclusive evidence of any benefit from community mask use.
            d) A June 2020 systematic review conducted for the WHO has come under fire. Researchers have found several flaws including that this review contained NO randomized controlled trials. Rather, the review was of observational studies, many without verifiable outcomes with no control for contextual co-factors.The authors own conclusion states: “Robust randomised trials are needed to better inform the evidence for these interventions, but this systematic appraisal of currently best available evidence might inform interim guidance.” Their own evaluations of “certainty” of their estimated inferred benefits of the measures are (their Table 2):
            ● Face mask: “LOW” = “our confidence in the effect estimate is limited; the true effect could be substantially different from the estimate of the effect”

            1. The cloth masks study where the healthcare professionals wore medical masks and much of the control group wore medical masks and cloth masks had something like a 79% increase risk of infection is almost more of a good mask versus bad mask study and good masks having that much greater benefit counts as a pro-good mask argument to me.

        3. I went to another one and it said that the materials of the masks may have changed and

          when I went to the history of mask usage, I found that in 1994 the CDC specifically called for masks to deal with mycobacterial tuberculosis.

          https://www.cdc.gov/niosh/npptl/Respiratory-Protection-history.html

          Then, later, the CDC says that The TB infection-control measures recommended by CDC in 1994 were implemented widely in health-care facilities nationwide (8–15). As a result, a decrease has occurred in 1) the number of TB outbreaks in health-care settings reported to CDC and 2) health-care–associated transmission of M.

          1. The authors in one of your links conclude that the results are unclear.

            Certainly, you have a lot of passion but the review people didn’t come to ANY conclusion, so I guess we move on to more recent studies.

            Some of the studies reviewed in it included people who weren’t scrubbed and might not have much access to patients and others were canceled early because of too contaminated of a space.

            It seemed overall not very helpful.

            Almost more of a “More research needed.” answer.

          2. Its not new that masks are recommended in healthcare settings. What is ridiculous is the expectation that laypeople can be expected to safely mask without contaminating themselves, others and the environments. Trained doctors and nurses continually contaminate themselves during mask removal. I have yet to anyone santize their hands after mask use which are usually crumpled up and left in their pockets, reused, hanging around neck etc. Its a joke and a total infection control hazard. The mask is a con of massive proportions

            1. Masks aren’t a perfect way or preventing the spread of covid 19 so therefore they are useless?

              That logic is hugely unconvincing.

        4. Right now, Chinatown in San Francisco talked about how things like masks kept them having much lower rates than the surrounding areas.

          Yes, it is anecdotal.

          But there are so many anecdotal evidences like that.

  6. Dr Greger, I have followed your work, have your books, & refer people to your work often. However, I can not support this video & the heavy message that it carries. Masks are not healthy for us to wear. Check out Dr. Rashid Buttar, Dr. Eric Nepute, & the actual mask companies are saying that masks don’t prevent the contraction of any viruses namely Covid -19. This video feels politicized & that’s never a good thing. Our health & well-being is centered around our ability to breathe. After you breathe on a surgical mask or on a homemade mask that made with plastic material (guess what most fabrics contain plastic nowadays especially from discount stores like Walmart & Target) as a person breathes in & out the condensation from their breath breaks the plastic down & the person is now breathing in toxic plastic materials AND breathing in more CO2. Dr Buttar suggest wearing masks is creating a hypoxic state and that wearing a mask is like putting up a chainlink fence to keep mosquitoes out. It doesn’t make sense.
    Furthermore, if we were really concerned about CoVid, then why aren’t there hazardous waste bins everywhere for old masks & gloves?
    If masks worked, then China who has been wearing masks for years would have not spread so MANY viruses all over the world. Most of our viral issues come from China. What about countries that wear full hijab? They should not have any cases of CoVid, or very few! But they absolutely had MANY test positive.
    Testing is another issue with this entire debacle. The FDA says…let any company make a test because we need as many tests as we can get. This resulted in faulty tests & results. Now, the FDA has had to recall over 50 companies for faulty tests. Do you think those faulty results were taken off the stats that the MSM reports on daily? I’m willing to wager that they did not.
    I’ve read data that the 3 types of tests available are actually not for CoVid-19 specifically that they test for all coronaviruses & rhinoviruses. So, someone could merely have a common cold & test positive.
    I’ve read reports that a family member died of suicide & they said the patient died from CoVid. I’ve heard doctors testify that they receive more funds when they say the patients test positive or die from CoVid.
    Just as people die every year from many viral threats, there are typically co-morbidities involved.
    I think the world of you & love that you’re helping people see less disease by adopting a plant-based lifestyle. But this video’s content goes against the very breath of life we need to survive & defies common sense.

    1. Christy,

      The newest studies have been showing that the states in the USA that have mandated mask-wearing have lower transmission than the states that have not mandated mask-wearing.

      1. Oh and can you provide me with these studies Christy, I am guessing they are swayed to justify this draconian and poorly supported practice. I find alleged study odd because since Dr Greger apparently like to “put it to the test’ The only randomized controlled trial (RCT) conducted on cloth face masks involving 1,607 hospital healthcare workers found cloth masks posed a 13% INCREASED risk of Influenza-Like Illness infection to those wearing them. The study authors note “moisture retention, reuse of cloth masks, and poor filtration may result in an increased risk of infection.”
        – The same RCT found particle penetration of cloth masks was almost 97%.
        – Researchers with the University of Edinburgh found that surgical, hand-made masks and face shields generate several leakage jets, including intense backward, side, and downwards jets caused by heavy breathing and coughing “that may present a serious hazard of environmental spread”. The researchers express concern about these jets “that people are not aware of and that could be a major hazard to others around them.”

        1. Penelope,

          THAT study was comparing cloth masks to medical masks in a healthcare setting.

          Medical masks BEAT cloth masks. Surprise, surprise.

          Even the control group in that study was using masks and that control group was allowed to wear medical masks or cloth masks, so guess which masks the medical people in the control group chose?

    2. Hijabs are thin fabric. THERE IS A REASON WHY homemade masks are recommended to be multi layer. Also since you clearly never have actually paid attention, before covid-19 most people in Asian countries do not wear masks even though many people do.

      And DECADES of research not only have shown masks prevent the spread of disease. Ask any surgeon who wears them for hours to prevent sepsis in patients.

      Also new research has shown that masks CAN MAKE A COVID INFECTION MILDER.

      https://www.sfgate.com/news/article/Masks-offer-much-more-protection-against-15407103.php

      1. This is not true at all and Funny you should bring up surgeons – the mask is more to please public perception and to protect the wearer from splashes than infection control during surgery. From a early as 1981, researchers have concluded wearing of a mask had little relevance on infection rates https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2493952/pdf/annrcse01509-0009.pdf A 2016 Cochrane review of mask use during clean surgical procedures studied three trials, involving a total of 2106 participants. There was no statistically significant difference in infection rates between the masked and unmasked group in any of the trials. the Authors noted “facemasks themselves may actually serve as a source of to contaminate the surgical wound, e.g. by incorrect wear or by leaking air from the side of the mask due to poor string tension. “” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7138271/
        this one? https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD012653.pub2/full?highlightAbstract=infection%7Cpreventing%7Cdispos%7Cin%7Cfor%7Cmasks%7Cclean%7Cwinded%7Cdisposable%7Csurgeri%7Cprevent%7Cdisposabl%7Cwound%7Cface%7Csurgic%7Cfour%7Csurgical%7Cwind%7Csurgery%7Cinfect%7Cmask

        Masks for the general public are a joke.

    3. There have been a lot of people wearing masks all day, from doctors, to the people at Disney World who have been measuring their pulse ox after a whole day of wearing masks and there has been no change.

    4. Christy, note that in addition to the faulty test results that were likely never removed from the number of positive COVID cases, there is a true “scamdemic” in the southern states that reopened early. Employers require employees to test before returning to work, and those who test positive, even if asymptomatic, cannot return to work until they test negative. If the person takes two, three, four weeks to be completely free of the virus, and ready to return to work, that one individual is counted as multiple COVID positive cases. So one person could well be counted as COVID positive ten or twenty times, depending on how often he goes in to retest. This explains in part why there is a spike in cases in TX and FL but not the expected increase in deaths. The other reasons for lack of a spike in deaths include the fact that few of the employees required to test are seniors in that higher risk over 65 group, and that better treatment protocols are in place. And the hospitals here have been mostly full of people seriously ill with other ailments, people who were unable to get care earlier due to physician furloughs and bans on elective surgery, or who were so afraid of dying from the virus that they refused to go to a hospital for needed care.

      1. And not only employers are requiring the tests, but also hospitals and some doctors who are now seeing patients who postponed care during lockdowns and bans on elective surgery. So the same person may be required to test multiple times, inflating the testing numbers.

  7. A sewing shop in LA tested all sorts of cloth and found that blue shop towels filtered Covid-19 sized particles the best. So it may help to layer blue shop towels inside your face covering. Suay Sew Shop is producing masks to donate to area hospitals and have posted the patterns for the masks online for anyone handy with a sewing machine. https://suayla.com/pages/suay-community-mask-coalition
    https://www.reporter.am/designers-say-layers-blue-shop-towels-inside-cotton-masks-could-help-effectiveness-of-homemade-ppes/

  8. Is it correct that WHO still does not recommend face masks for most people? My impression was that they too had revised their recommendation.

      1. LOL yes it has been correct my dear. Look it up! The WHO is a geopolitical organization run by Bill Gates, not a health authority. They have zero credibility, nor does the CDC. They keep changing their minds as case fatality rates fall from bloated projections of 4% to 0.25% overall.

        1. Penelope, you sure aren’t in health care! Where do you get those numbers?
          In my state, one of the healthiest in the US, our fatality rate is higher than that! And no one is counting people dying of something else. Of those needing medical care, we are losing about 12%. And that rate is far lower than in most states.
          We’ve had a number of people dying of it that didn’t go to the hospital. They believed people saying it’s no big deal.
          We have great medical care also.
          Most masks probably don’t protect you, but they protect others. Seems like so many people no longer consider other people.

          1. Also, within days of the hotspots mandating masks indoors in public places, rates have already gone down by 40%.
            So you say masks don’t work??? Well, apparently they do!

            1. Here are some of those recent studies.

              https://www.washingtonpost.com/health/2020/06/13/spate-new-research-supports-wearing-masks-control-coronavirus-spread/

              Here are studies on SARS1, MERS, and maybe other things with PPE being one of the most important factors.

              https://www.acpjournals.org/doi/10.7326/M20-1632
              The paper, led by Roger Chou, director of the Pacific Northwest Evidence-based Practice Center at OHSU and a professor of medicine in the OHSU School of Medicine, was a meta-study that analyzed the results of 64 separate studies about the impact of PPE on virus transmission. They date back to 2003 with the rise of SARS, account for data on MERS (first reported in 2012), and even included a few early studies on SARS-Cov-2 (the virus that causes COVID-19).

              “We were trying to take the evidence from viruses that we thought would be most like COVID-19,” Chou says, noting that all of the analyzed studies examined novel coronaviruses, which caused similar upper respiratory symptoms. The conclusion? “PPE definitely did seem to help,” he says. “In terms of the impact . . . in general, if you look at [individual healthcare workers] using masks versus no masks, the risk of being infected drops by anywhere from 50% to 80%.”

              “Evidence on risk factors for coronavirus infections in HCWs is primarily available for SARS-CoV-1, with the strongest evidence indicating an association between PPE use versus nonuse and decreased risk. The association was most consistent for masks but was also observed for gloves, gowns, and eye protection, as well as handwashing. There was evidence that more consistent and full use of recommended PPE measures was associated with decreased risk for infection, suggesting a dose–response relationship, and evidence that N95 respirators might be associated with decreased risk for infection versus surgical masks.”

        2. So, there we have it.

          Crank magnetism at work. Not only does Penelope buy the ‘masks are some sort of conspiracy against the public’ meme, she also believes that Bill Gates runs the WHO and assorted cranks have more credibility than the WHO and CDC.

          ‘A sovereign citizen, a creationist, an anti-vaxxer, and a conspiracy theorist walk into a bar. He orders a drink.
          Crank magnetism is the condition where people become attracted to multiple crank ideas at the same time. Crank magnetism also denotes the tendency — even for otherwise “lone issue” cranks — to accumulate more crank beliefs over time. You know that old saying about not being so open-minded that your brain falls out? People with crank magnetism didn’t pay attention to that.’
          https://rationalwiki.org/wiki/Crank_magnetism

      1. Hmmm talk about zero credibility… lets see if I get the dizzying contradictions right…When the virus was reported to have a bloated and grossly overestimated death rate of 3-4% by the worlds crappiest modeller – the WHO and the CDC told us masks weren’t necessary for the asymptomatic.Now the death rate has plummeted and yet we are suddenly all supposed to be masked? I smell a large rat….

        The reality and the 24/7 fear based narrative arent jiving: The virus indeed has a 0.25% death rate as per the CDC about that Case fatality rate plumments to as low as 0% for those under 45 – as per the King of meta research at Stanfords John Ioannadis:

        “0.05% to 1% is a reasonable range for what the data tell us now for the infection fatality rate, with a median of about 0.25%. The death rate in a given country depends a lot on the age-structure, who are the people infected, and how they are managed.
        For people younger than 45, the infection fatality rate is almost 0%.
        For 45 to 70, it is probably about 0.05-0.3%.
        For those above 70, it escalates substantially, to 1% or higher for those over 85. For frail, debilitated elderly people with multiple health problems who are infected in nursing homes, it can go up to 25% during major outbreaks in these facilities.”

        Draconian Lockdown Consequences: “Financial Crisis, Unrest, and Civil Strife.”

        “I feel extremely sad that my predictions were verified. “Major consequences on the economy, society and mental health” have already occurred. I hope they are reversible, and this depends to a large extent on whether we can avoid prolonging the draconian lockdowns and manage to deal with COVID-19 in a smart, precision-risk targeted approach, rather than blindly shutting down everything. Similarly, we have already started to see the consequences of “financial crisis, unrest, and civil strife.” I hope it is not followed by “war and meltdown of the social fabric.”

        Yet our government has put us in a Draconian Lockdowns put 1.1 Billion at Risk of Starvation

        Dr. Ioannidis replies:

        “Globally, the lockdown measures have increased the number of people at risk of starvation to 1.1 billion, and they are putting at risk millions of lives, with the potential resurgence of tuberculosis, childhood diseases …, and malaria. I hope that policymakers look at the big picture of all the potential problems and not only on the very important, but relatively thin slice of evidence that is COVID-19.”

        1. Which countries did draconian lockdowns?

          I looked at one list of countries and it only listed China and Italy as having done draconian lockdowns.

          I know that the USA never shut down even 50% of its population.

            1. I looked up what the experts are considering a “lockdown” and found this: While “lockdown” isn’t a technical term used by public-health officials, it can refer to anything from mandatory geographic quarantines to non-mandatory recommendations to stay at home, closures of certain types of businesses, or bans on events and gatherings, Lindsay Wiley, a health law professor at the Washington College of Law, told Vox.

              So they would still use the word “lockdown” if only bars are closed or if there are “recommendations to stay at home” or if they didn’t allow people at the fireworks???

              I will definitely be looking up the food issue. I do know that in pandemics from long ago, there were often problems such as farmers dying that did contribute to food scarcity. Though, sometimes the food scarcity was caused by drought unrelated to the pandemic.

                1. I did find pages about global hunger and there were things listed like war and locusts that have nothing to do with COVID-19

                  As far as how COVID-19 will affect the countries, they mentioned lack of tourism to poor countries, which will still be true because people don’t want to go on planes or cruise ships.

                  They also mentioned the drop in oil prices which helps the poor in a lot of countries, but people don’t want to travel while so many people are infected.

                  The third thing they said was that people won’t send money to their relatives in poorer nations if they don’t have jobs. Most of the richer nations have had unemployment and programs to help businesses with payroll. I talk to my friends in other countries and I don’t know any wealthier country that hasn’t been providing for people who are unemployed during the pandemic.

                  The truth is, countries like the USA are having so many hospitalizations right now and so many ICU’s being filled to capacity that it will affect our economy no matter what and we can’t do the tourist things no matter what and people don’t want to travel even though places are open to travel to within our country and that not wanting to travel is not because the government says not to. People here don’t want to take the risk.

                  Much of the world is already opening but I do know that the USA does affect the global economy and our part is just not going to be the same and that has nothing to do with lockdown right now because we aren’t really locked down almost at all and haven’t been in lockdown for months now.

                  But we still have changed our behaviors out of perceived threat.

                  1. I remember listening to an interview when Sweden started having cases and with no lockdown, the person said that there was only about 10% of the population doing their normal summer vacations.

                    The USA in lockdown had more people traveling than that.

                    1. Schools opening in the fall in the USA is another example. My relative was talking about how every parent in her daughter’s grade has said that they aren’t sending their kids to school.

                      I just heard people on television saying the same thing.

                      The parents have minds of their own.

        2. I want to talk about the whole starvation thing.

          The thing is we aren’t having a food shortage right now. We have poverty as an issue and there are wars and locusts and whether people will give to all of the charities that are feeding people, etc.

          But we can grow meat out of air and we can 3-D print any type of fruit or vegetables in hours. Technology is so different now.

          https://www.airprotein.com/science

          So, it is mostly about distribution being delayed right now, but even with the serious disruptions at the meat-processing plants in the USA by COVID-19, we still are at 97% even in meat.

          Are people poorer, yes, but people will not travel by air or by ship until those industries get creative and figure out how to stop the spread and prove they can do it. The airline industry is almost there, except for the airports. If they want people to fly, they can invent their own super-duper air-filtered masks with little fans in them, just like the money-grubbing world already has invented. Or they can use cameras or whatever to decrease the risk enough so that people can travel and bless the global economy. Those issues have not been dealt with and it isn’t lockdown causing people to not get COVID on a cruise ship or an airplane. They have to prove they can figure out systems to protect people and they haven’t done it as industries yet.

          I am routing for the airline industry because they went from 72 people getting infected with the flu to 24 getting infected with SARS 1 and they improved things so much that it was half of one row who got it. They are doing so great. But 1000 TSA agents undermines their cause.

          1. Our school district just did a survey in the last 10 days. Our high school 9th – 12th grade has 4,479 kids. 2,151 parents responded to the survey and 84% plan to send their kids to school. Some parents are even starting a protest group just in case our school moves 100% online.

            The death rate for younger kids is higher with the Flu as compared to Covid.

            *** Professor Peter Collignon, an Australian microbiologist and infectious disease physician, writes the following.

            “The data from a range of countries shows that children rarely, and in many countries never, have died from this infection. Children appear to get infected at a much lower rate than those who are older… there is NO evidence that children are important in transmitting the disease.”

            Furthermore, a new paper published by medical experts at Colorado State University and Yale University says that “What we know about social distancing policies is based largely on models of influenza, where children are a vulnerable group. However, preliminary data on COVID-19 suggests that children are a small fraction of cases and may be less vulnerable than older adults.”

            By the way, we do NOT close schools or daycare centers during Flu season and so far, we are the ONLY country on planet Earth even considering not going to school.

            Professor Collignon writes “Many will likely miss out on over six months of teaching if we don’t open schools. While online learning might be available it is nowhere near as effective as face-to-face teaching. Minimal or no mixing with their friends and other children for over six months will also have deleterious effects.”

        3. Also, and, mainly, if you train people not to care about the people dying from COVID-19, the same people will also not care about people dying from starvation globally.

          I am a Christian and all of the churches feed people globally, but most people, the vast majority, already don’t care about global starvation or global poverty or racism or sexism or the fact that 1 out of 6 prostitutes get murdered or that 60% of foster kids go to prison or are homeless, usually alternating between the two.

          The thing about caring is that the people in England who gave up everything in their lives to protect the nursing home patients for months will also be the people who will give food to a food bank or blankets to a cold homeless person. Life is like that, you train people not to care and they find other things to not care about using the exact same logic.

  9. Neat.

    Seeing all the variations on facial hair someone compiled. And seeing real numbers for masks effectiveness from testing.

  10. NOTHING about vented masks being deemed INAPPROPRIATE FOR COVID USE by the makers of those vented masks and many public health departments. Again NOT IMPRESSED with this lifestyle doctor trying to play public health expert.

    “Any mask that incorporates a one-way valve (typically a raised plastic cylinder about the size of a quarter on the front or side of the mask) that is designed to facilitate easy exhaling allows droplets to be released from the mask, putting others nearby at risk”- San Francisco Public Health Department

    The 3M company, which makes valve masks illustrates on its website how they work: Inhaled air is filtered through the fabric part of the mask, and hot, humid exhaled air goes out through the valve. The system may be what you want when tearing out a kitchen for remodeling, but the valve defeats the purpose when you’re trying to slow the spread of a virus.

    Public health experts have been recommending mask-wearing to prevent respiratory droplets from spreading into the air when you exhale, speak, cough or sneeze, and the valves allow those droplets through as if the wearer is not wearing a mask at all.

      1. People all over think vented masks work like the rest. I have seen only two people wear another mask over the vent since covid started and I was one of them.

      1. Deb, you might want people spreading covid with vented masks but other people do not. There is no ‘best of both worlds’ in pandemic control. Perhaps you should try taking it more seriously.

          1. I would rather see people all use vented masks than whole states not wear them at all.

            I want even better vented masks with the fans inside.

            Because way too many people are wearing their masks on their chins.

      2. Deb,

        Why on earth would anyone wear a vented mask? It may protect the wearer, but it does nothing to protect anybody else. And as noted in the video, most N95 masks do not protect the general public from the virus, because these masks are neither fitted properly nor worn properly. And they are not handled properly.

        1. To assume that people do not know how to properly fit a N95 mask is an assumption by Gregor trying to play public health expert. Many people do know how and if they didn’t there are videos and such online to show them from medical schools.

          1. Hey RB
            if you were a healthcare worker you would realize what a big deal a proper fit is. We have to be sized every 6 months under rigid procedures using hoods etc as per OSHA guidelines. Fit is everything and these masks dont fit, they are a joke and leakage leads to severe air jets during coughing etc that project virus farther than without a mask. Masking the public is a bad idea.

            1. Understood. Public won’t do what you have to do. Most of us will do the best we can.
              Be well.

              My u.arizona email address (all of them addresses) should be working now. Use what you like.

            2. Penelope, same for the military. They are measured for mask size, plus they can’t have facial hair that interferes with the fit of the mask. Only a very narrow “military mustache” is permitted. Due to the popularity of facial hair among men these days, it is likely that few of them have merely a military mustache or less.

        2. Dr J.,

          People wear them because of how much easier it is to breathe through and it is a N99 to protect them higher than even an N95, but then they put a paper mask over it to cover the vent.

          1. The reason that I say it is that people say that they feel faint wearing one and wherever I go, I see people with masks pulled down to expose their noses trying to get fresh air. My coworker said that he stopped someplace on the way to work and saw 4 people with their masks below their nostrils and that is what I am seeing every single day.

            Having more effective, more breathable masks might help. If everybody were wearing the kinds with the vents, everybody would have N99 protection and people could feel like they could breathe better.

            It won’t happen unless someone starts handing them out, but for workplaces and homes, it could already happen.

            I watched the oil change people taking breaks every few minutes to breathe and I do know that having to wear masks is a really big deal for some people particularly when they have to wear them all day long.

            1. I also wonder if people wearing vented ones being more compliant and more likely to not expose their noses and less likely to get it, well, people who don’t get it, won’t spread it.

              Plus, hospitals have used the surgical masks over the types of N95’s with exhalation vents and that has been studied.

    1. RB

      Your attacks on Dr G on this issue are becoming more and more illogical. Frankly, I’d be happier if he stuck to nutrition too. That is the purpose of the site after all. However, none of your specific criticisms that I’ve seen seem to hold any water.

      For example, you criticise him here because he doesn’t mention vented masks in the context of information about masks/face coverings for the public. Many if not most other public health authorities don’t mention them either in that context. Yet I suspect that you wouldn’t have a similar apoplectic fit when eg the LA County Dept of Public Health doesn’t mention them either even though it, like Dr G, does mention N95 respirators in that context..
      http://www.publichealth.lacounty.gov/media/Coronavirus/docs/protection/GuidanceClothFaceCoverings.pdf

      It seems like you are employing a double standard when you insist that Dr Greger should be held to higher standards than US county public health departments .

      1. Neither the CDC nor WHO mention vented masks.

        And, Dr. Greger covered their positions better than the spokespeople from those agencies.

        1. Yes Deb.

          RB seems to be flailing about trying to find some reason, however flimsy, to criticise Dr G for posting info on this topic. I don’t see why. From what I have seen, just as with nutrition, Dr G’s posts and videos seem to be entirely in line with the mainstream scientific position. Which is probably why all the ‘alternative’ people here rail against him too.

          I am only surprised that the anti evolution crowd haven’t yet had a go at him for stating that the virus evolved from viruses infecting animals. After all, that can’t be true since evolution isn’t real. Therefore covid 19 can’t be real either.

          1. Smiling. We already have had people saying that viruses don’t exist. and that they don’t kill people.

            I guess that is close enough.

  11. From what I’ve read (I think from the CDC’s mouth itself), is that transmission by ‘asymptomatic’ people is very unlikely in the case of what is called ‘covid-19.’

    Never mind that *the* so called sars-cov-2 virus never has been purified and subsequently shown to be the cause of what has been named ‘covid-19. Purification and cause-relationship is, according to epidemiologists a must for describing a virus and its connection to a particular disease. This crucial step for the entire ‘pandemic’ has been skipped (just as safety testing for gene modifying and other toxic cov-19 vaccines has is being skipped).

    Also interesting is that at least in the US, there is no (longer any) emergency which makes all or at least most of today’s ’emergency orders’ illegal. Law suits are being filed accordingly. If the justice system isn’t beyond corruption, we should see some ‘experts’ and politicians hit the bunk beds in jails and prisons.

    According to the CDC, the ‘symptomatic case fatality rate’ of covid-19 is, averaged over all age groups, 0.004.

    According to the CDC, covid-19 is close to losing it’s standing as pandemic.

    According to the CDC, sars-cov-2 tests are all unreliable (they use a more flowery term). Every test insert text I have read so far states that the covid-19 tests are not to be used as diagnostic tools (this applies to both the rtPCR and ELISA/blood tests). No wonder, these tests are all based on a not purified and described ‘virus’. It has been shown that you can test positive and or negative within days; that tests cross react with other coronaviruses, that there are false positives and false negatives; that some batches were contaminated with the sars-cov-2 itself; that even fruits test positive for sars-cov-2.

    According to Dr. Birx (video still available), ‘The US takes a generous stand on mortality; every death where covid-19 was assumed or confirmed by (unreliable) testing is counted as covid death.’

    According to the CDC, death certificates need to be completed by adding covid-19 and thus declaring the death as a covid death, when covid-19 was suspected or determined (by an unreliable test) as present, independently whether this ‘virus’ was the cause of the death or not.

    According to the study of Boyman’s research group in Switzerland, the current antibody tests only catch, at most, 20% of all cases where a person was exposed to that ‘virus.’ This means, the actual mortality rates, although based on intentionally inflated death counts, are even lower than officially stated.

    The ‘second spike’ we’re being ‘sold’ now by illegally acting authoritarians/authorities and their media puppets, are based on increased testing numbers, the testing of anybody who finally is able to be seen by a doctor or in a hospital for non-covid-related ailments, the counting of multiple positive tests run on the same person, and of course less than reliable tests.

    Case counts go naturally up by giving clinics and hospitals financial incentives to test more (one rtPCR tests can be billed from $1.500-4000).

    Case counts go naturally up if the CDC gives instructions to classify anybody as covid patient/case if 2 of mostly very vague symptoms are found to be present, this includes ‘subjective fever’, headaches, shortness of breath (jeeze, I must be a covid case since sprinting made both hot and got out of breath this morning).

    ‘Covid death’ counts go naturally up by giving hospitals financial incentives to declare more patients as covid patients (from $9,000 and up). And even more (> $39,000, I think) if they put a ‘covid patient’ on a ventilator. Although ventilators have been shown to be deadly to most of the ‘covid patients.’

    What masks are doing is humiliate the population (so does being classified as ‘non-essential’.) and to dehumanize people (are you ready for your digital implanted ID or health passport?).

    Do we really have to have ‘authorities’ to tell us to wash our hands and to cover our mouths and noses because we’d be otherwise sneezing, coughing and spitting at other people? I assume every child has heard it dozens of times from their parents: Cover your mouth and nose when sneezing or coughing. We don’t really need the WHO, UN and CDC to tell us this, or do we?? (If yes, what species am I part of?)

    What happened to tissues, which can be changed and disposed of after each use if necessary (or replaced and washed)? What happened to keeping away from others when sick/symptomatic? What happened to the gold standard that worked before, where susceptible people protect themselves esp. if they have to go out?

    The goal is to get the ‘Green New Deal’ up and running; to reset the economy (search for: World Economic Forum – the great reset); to establish global governance with complete control of the ‘normal’ people (see http://www.UNNwo.org – seriously). To control and surveil people (why does anybody think they pushed harmful 5G (search for declassified Russian study/review millimeter wave) like crazy although none of the ‘normal’ people asked for it or wanted it? It’s a measure for surveillance and even is already used for mass control (and worse). Do your research. P.S.: Symptoms of covid-19 do resemble what’s described by live blood microscopy after radiofrequency (cell phones, WIFI, smart meter) exposure. It’s not surprising that some people think there was/is a connection to this technology and the seen ‘covid’ symptoms.

    All the rights we’ve lost won’t come back if we aren’t watching carefully. The rights we’ve lost after Sept 11 haven’t come back. The rights we’re losing now won’t come back either (b/c we’re so much easier controllable without them). Soon we’ll have no more rights and liberties to lose….
    If you’re OK with that, put on your contaminated oxygen-restricting, CO2 increasing mask, take the vaccine and believe everything your politician or health authority and their media puppets tell you without doing your own research. How does the saying go: “Those who would give up essential liberty, to purchase a little temporary safety, deserve neither liberty nor safety”

    1. You typed all of that just to say you do not know that sars-cov-2 is the name of the virus and covid-19 is the disease it creates.

      And masks DO NOT RESTRICT OXYGEN, they have holes. It is not a plastic bag. Oxygen deprivation IS NOT SUBTLE so stop it with the childish tantrums and clear lack of medical comprehension trying to act like it is happening when it is not.

    2. Gertrude Wilson Smith,

      I stopped reading your very long comment after the first two paragraphs. You clearly have no idea what you are talking about. SARS-CoV-2 has been clearly established to be the causative agent of the current pandemic.

      However, I’m willing to keep an open mind if you can provide us all with a link to even one credible scientific article published in a peer reviewed journal to support any of your statements in your first paragraph. However, it would have to be an extraordinary paper, to go against the weight of at least thousands or tens of thousands published papers on these topics to date: Extraordinary claims require extraordinary evidence.

    3. That is very interesting. Since the beginning of this “pandemic” I am waiting a proof of the virus. And they never proved it. Like it said above the virus was isolated but not purified. Is that a new way to do science? To do only a part of science and forget intentionally another? And with this half truth half lie they show to the ignorant people that the virus exist. What a shame. Just because all the mainstream media have the same narrative doesn’t make it true.
      Still waiting for science behind the propagation of the virus.
      Our main problem: ignorance
      And if you read an article who is using science to prove his point, go read the article and make sure it says the same things, check who founded the study and if there is any conflict of interested.
      Be careful guys, money can buy anything today, even a pandemic.

      1. Steve,

        Do you know how to do a google search? Type in “Purification isolation of viruses” and actually look at some of the results.

        EG: http://eacharya.inflibnet.ac.in/data-server/eacharya-documents/55d44ff9e41301fd23d8facc_INFIEP_203/660/ET/203-660-ET-V1-S1__lec_6.pdf
        “Lecture 6: Isolation and purification of viruses and components”

        That’s for background. Then search for “sars-cov-2 isolation and purification” and look at some of those results.
        EG: https://www.biorxiv.org/content/10.1101/2020.03.02.972935v1.full.pdf
        “Isolation and characterization of SARS-CoV-2 from first US COVID-19 patient”

        Then you will no longer be waiting for “proof of the virus.”

        Enjoy! And, you’re welcome.

        1. Thanks Dr J to show me a scientific paper : A reminder: these are preliminary reports that have not been peer-reviewed. They should not be regarded as conclusive, guide clinical practice/health-related behavior, or be reported in news media as established information.
          Very scientific approach.
          And by the way it seems that there is couple of error in the paper.
          Continue your misinformation.
          I am out of nutritionfacts.org as it is a place of propaganda not science.

          1. I get the impression that you wouldn’t recognise science if it marched up to you and beat you about the head with a large piece of 2×4.

    4. Gertrude Wilson Smith,

      Every single person who goes to the hospital gets tested for COVID-19 now. There isn’t the same level of guessing anymore. There are still false test results, but the studies testing the USA PCR test accuracy was from 66 percent to 88 percent accurate and that was up from the other tests that were 50% accurate.

      There are more false negatives and that is related to the fact that sometimes the virus doesn’t replicate in the nose or mouth. They said that sometimes it is in the GI tract. (I forget, did it spread through intercourse? Enemas or suppositories? All that pops into my brain was that stupid peach.)

      As far as the CDC contemplating taking away the pandemic status, we are in the summer and the cases generally lower in the summer, but that has not happened in the USA and we have progressed from having more cases to more hospitalizations, to more ICU’s being filled to 5 states having more deaths.

      This isn’t going away any time soon.

      We will see what happens in the coming fall and winter seasons.

      1. First of all we determine a pandemic with the number of death, not cases. The number of death of this years have nothing spectacular are something very similar with the past years. So NO PANDEMIC here.

        Second, how do we count cases? In US and lots of others countries, count 1 the person who is tested positive and all the person who were in contact with this person (probable cases). So if the one infected had been in contact with 25 persons there will be 26 cases. So this is how we pimp the cases. https://www.youtube.com/watch?v=_7xzjd583uo

        But whatever the number of cases it doesn’t change anything, the death rate is dropping critically and the virus is so weak that it will disappear very soon (as soon as we will stop the propaganda ;-)

        Oh by the way here the WHO : https://www.youtube.com/watch?v=NQTBlbx1Xjs

        1. Steve,

          We have barely started in the USA with COVID-19 and 20% of our deaths are people under the age of 65 and our hospitals and ICU’s are filling up and most of the states have an R Naught above 1 right now. We have just starting having the deaths in the states that had opened up and we haven’t reached the fall yet.

    5. Right on Gertrude. Finally someone who sees through the fear mongering to the reality of the greatest health and human rights fiasco in US history.

      1. Thanks Sara, I am surprised how easy it is to take peoples’ rights away. Fear and the desire to fit into one’s chosen group’s group think are great motivators, and this is being abused by those in charge of the narrative. Again and again. Because it works.

        1. Yesterday there was a recorded 3789 deaths due to COVID19 worldwide (that is if you believe the numbers).

          This represents ~7% of daily deaths due to cardiovascular diseases or 14% due to cancer. Yesterday. a comparable number of people died of tuberculosis or of HIV/AIDS .
          https://weforum.org/agenda/2020/05/how-many-people-die-each-day-covid-19-coronavirus/

          “Children infrequently transmit Covid-19 to each other or to adults” according to Pediatrics, the official peer-reviewed journal of the American Academy of Pediatrics. https://sciencedaily.com/releases/2020/07/200710100934.htm…

            1. Given the number of deaths occurring, and the likelihood of a proportion of those being due to the circulation of misinformation about covid 19, it might well be appropriate if those engaged in spreading that misinformation were arraigned on manslaughter charges.

              1. At least they admit it BS testing – https://m.facebook.com/story.php?story_fbid=3151129788277372&id=100001411465184 Social distancing and dying alone: With strict no-visiting limitations in place, patients have been dying alone. In an editorial in the journal Intensive Care Medicine, researchers suggest an alternative pathway to patients dying alone in a hospital. They advocate that infection control, public health concerns, and family-centered care can coexist and urge reconsideration of adult family member presence at the bedside of patients during COVID-19. STOP the insanity!

                Schools – Professor Peter Collignon, an Australian microbiologist and infectious disease physician, writes the following.

                “The data from a range of countries shows that children rarely, and in many countries never, have died from this infection. Children appear to get infected at a much lower rate than those who are older… there is NO evidence that children are important in transmitting the disease.”

However, preliminary data on COVID-19 suggests that children are a small fraction of cases and may be less vulnerable than older adults.”

                By the way, we do NOT close schools or daycare centers during Flu season.

                Professor Collignon writes “Many will likely miss out on over six months of teaching if we don’t open schools. While online learning might be available it is nowhere near as effective as face-to-face teaching. Minimal or no mixing with their friends and other children for over six months will also have deleterious effects.”

                Under the new metric, the CDC estimated that 0.65 % of people infected with COVID-19 are forecasted to die. This new number is only slightly higher than an average seasonal flu death rate.

                American Academy of Pediatrics: Kids could have ‘suicidal ideations’ if schools don’t reopen

                Dr. Sara Goza says ‘the goal should be to have students physically present in the school’ Not being in school? “It can lead adolescents to become depressed and anxious, and even [lead to] suicidal ideations. Those are all good reasons why we feel these school should be trying to open up.”
                “After weighing what we know about children and the coronavirus, we really strongly advocate that the goal should be to have students physically present in the school,” AAP President Dr. Sara Goza said.
                Despite the surge in confirmed cases — approximately 40,000 per day, Goza said her recommendation is based on the “evidence we know right now, [that] COVID-19 appears to behave differently in children and adolescents compared to adults.”
                Goza warned the continuation of online learning could have negative ramifications if children cannot return to school in the fall.

                Virus Fears Caused Spike in Deaths From Unrelated Conditions: Cure worse than the disease?

                People who were terrified of seeking medical care during the pandemic may have died of untreated heart disease and other medical conditions.
                Deaths from heart problems rose 27% over historical averages in five hard-hit states and New York City during the months of March, April and May. Experts said that many patients suffering from serious conditions died as a result of delaying or not seeking medical care. The Post noted that during the early months of the pandemic, there were hardly any heart, cancer and stroke patients at hospitals. The new analysis revealed that more than 50 patients a day “died excess deaths just from heart disease, just in New York City,” said John Puskas, chairman of cardiovascular surgery at Mount Sinai Morningside Hospital in Manhattan. “Frankly, that would explain where all the patients went.”

                1. Covid !9 appears to cause heart problems

                  ‘: “Damage to the heart is known to occur in severe flu, but we were surprised to see so many patients with damage to their heart with COVID-19 and so many patients with severe dysfunction.

                  “We now need to understand the exact mechanism of this damage, whether it is reversible and what the long-term consequences of COVID-19 infection are on the heart.”

                2. The home schooling thing doesn’t ring true to me. Except for when children are in abusive or neglectful situations.

                  Fist off, suicidal ideation in children and seeking psychiatric care correlates HIGHLY with the school calendar.

                  https://fee.org/articles/children-s-and-teens-suicides-related-to-the-school-calendar/

                  I know so many people who home school very healthy, happy children, and, even before this, I had conversations with parents who said that because of things like bullying, their children had asked to be homeschooled to avoid the trauma of the school year. Three of those young people now are happy college students but had things that had caused them to be targeted at school. One has Tourettes. The college students are mature enough to be nicer and the professors in college are more supportive.

                  Anyway, when I was young, I was suicidal and it definitely correlated with the school calendar year. I was being abused, back then as a child, but the stress of trying to handle all of it and go to school and “fit in” when you are wrestling with major life trauma and everybody else just wanted someone to play with, was hard. I did have dear friends, but I didn’t do well with the masses and I seriously have amnesia of some of the school year times, but I loved summer and I loved learning, just not school.

                3. Also, I do know children who have done things where they ended up being responsible for the deaths of their grandparents. Two cases and one is a grown man who still struggles with deep psychiatric issues from the death of a grandparent where he made a decision and his grandmother died.

                  Another youngster at church did something and his grandfather died.

                  I contrast that to the almost 10-year old who comes and wants to play school with me and I know that her wanting to do the school books and wanting to play school all of the time is a sign that she is grappling with what happened to the year, but she has adapted so well. Bored sometimes, but she isn’t even going to go back to school in the fall even though they are open and she doesn’t care so much about that. But when I look to see what is on her mind, it is “What am I going to get for my birthday?” Will we be able to go to the bowling alley or play laser tag or go to the bouncy houses or butterfly museum or ride a pony? Can I have my friends over to the house? She just negotiated for one more friend and has already decided on an at-home theme.

                  When I asked her about school, she just talked about how nice the art teacher was and how mean the gym teacher was and those are what she wants me to role play with her.

                  She didn’t complain or mention fear of COVID-19 even once.

                  Just fear of having it disrupt her playtime.

                4. Read the article. It is compelling that suicidal ideation and suicide attempts don’t tend to occur during any of the vacations from school, but during school. Psychiatric breakdowns occur during school.

                  Particularly for boys (who are more likely to succeed at it) For boys, the suicide rate was, on average, 95 percent higher during the school months than during summer vacation;

                  What is most compelling is that Hansen and Lang also found that the school-year increase in teen suicide rate held only for those of school age. For 18-year-olds, most of whom would be finished with high school, the increase was barely present, and for 19- and 20-year-olds it had vanished.

                  Also, it was compelling that even though we have this sense of experts helping parents to be better parents, it is not when the children are alone with their parents that kids tend to kill themselves nor does it tend to be when they have psychiatric breakdowns. It is related to attending school.

                  I know that there will be exceptions where children are in serious abuse by parents and school was their only escape, but the statistics show that mostly, it is the opposite.

                  Mostly, children get healthier around their families and there have been studies that COVID-19 has helped families to bond more and has strengthened those relationships.

                  Yes, some kids are being abused more, but most kids are having closer relationships with their parents and my friends – the parents and grandparents are valuing this time so much that the ones who can work from home have already asked to do it permanently. They are eating healthier foods and having better conversations.

                  Years ago, they did a study where males only spent 5 quality minutes a day with their children. During this time, that has changed dramatically and many families have benefitted by the months of shut-down.

                  1. Reading those studies, there is a 300% less likelihood that the children who stay home will have psychiatric problems.

                    Suicide is most directly correlated to school stress.

                    If the suicide rates of children drop dramatically this year, parents need to figure out what schools are doing wrong.

                    1. Already, kids came home, couldn’t go places, learned about people dying, were at times at home in abusive families, had the stress of learning zoom and of not seeing friends, maybe worried about losing grandparents etc.

                      All of that is huge stress.

                      So, was there the “school stress standard” level of psychiatric breaks and suicides?

                      Someone, please get a researcher to investigate that.

                      Is suicide in children from stress or from a specific stress of school?

                    2. Teens couldn’t graduate, couldn’t go to proms, maybe can’t start college, were there more suicides than boys trying to survive being at school ?

                      College kids often commit suicide in the Spring, did staying home and doing classes online prevent that?

                      I highly suspect it will have even with undeniable stress.

                      So why are schools driving kids and teens to suicide? Are parents protective in the process, rather than causing it?

                    3. College would be another natural line.

                      Spring is the suicide semester,

                      It is arguable that there is more stress after graduation, if teens kill themselves more at college than in the finding a job phase of life, then education needs a change.

                    4. I go to Dr Greger’s book on med school.

                      So do more med school students’s kill themselves or doctors and that might be even-Steven.

                    5. Kids go hundreds of thousands of dollars in debt and maybe the whole concept of the college experience may not be all that healthy for many of them.

                      It is something young people who are vulnerable probably should evaluate before paying even more to go far away.

          1. Report: Florida health department misreported high positive COVID-19 cases:

            Countless labs have reported a 100 percent positivity rate, which means every single person tested was positive. Other labs had very high positivity rates. FOX 35 News found that testing sites like one local Centra Care reported that 83 people were tested and all tested positive. Then, NCF Diagnostics in Alachua reported 88 percent of tests were positive.

            How could that be? FOX 35 News investigated these astronomical numbers, contacting every local location mentioned in the report.

            The report showed that Orlando Health had a 98 percent positivity rate. However, when FOX 35 News contacted the hospital, they confirmed errors in the report. Orlando Health’s positivity rate is only 9.4 percent, not 98 percent as in the report.

            The report also showed that the Orlando Veteran’s Medical Center had a positivity rate of 76 percent. A spokesperson for the VA told FOX 35 News on Tuesday that this does not reflect their numbers and that the positivity rate for the center is actually 6 percent.

            “The Department immediately began working with those labs to ensure that all results were being reported in order to provide comprehensive and transparent data,” the spokesperson told FOX 35. “As the state continues to receive results from various labs, the Department will continue educating these labs on proper protocol for reporting COVID-19 test results.”

            Texas – COVID inpatient count ‘misinterpreted,’ level of alarm ‘unwarranted: Health officials in Texas are logging every single COVID-19-positive hospital patient in the state as a COVID-19 hospitalization, even if the patients themselves are admitted seeking treatment for something other than the coronavirus.

            Part of that trend may be due to liberal coding policies by state officials.

            The state is categorizing every inpatient in the state with a positive COVID-19 test as a COVID-19 hospitalization.

            The state does not keep track of the patients hospitalized with the coronavirus versus those hospitalized specifically because of it.

            The number of hospitalizations are “being misinterpreted,” said Methodist CEO Marc Boom, “and, quite frankly, we’re concerned that there is a level of alarm in the community that is unwarranted right now.”

            “We do have the capacity to care for many more patients, and have lots of fluidity and ability to manage,” Boom said.

            He pointed out that his hospital one year ago was at 95% ICU capacity, similar to the numbers the hospital is seeing today. “It is completely normal for us to have ICU capacities that run in the 80s and 90s,” he said. “That’s how all hospitals operate.”

  12. The video scoffed at the suggestion to use coffee filters. I have been inserting coffee filters into my cloth mask as an extra layer. Won’t that make my mask more effective?

  13. This video is confusing. Too much contradictory info. All he is saying is that “sources disagree”. Worse than no info.

  14. “Vigilant mask wearing might have spared nearly 140 people from catching the coronavirus at a hair salon in Missouri, according to a report published on Tuesday by the Centers for Disease Control and Prevention. In May, the people interacted with two hair stylists with confirmed coronavirus infections, but none ended up showing symptoms of Covid-19…[of the about half who were tested, none tested positive]

    a majority of people in the study, including the two stylists, opted for cloth coverings or surgical masks — loosefitting accessories that don’t form an airtight seal around the face.

    These products are imperfect. But several studies, including some initiated long before the pandemic’s start, have pointed to their usefulness in stymieing the spread of viruses from the wearer’s airway…

    BUT “We cannot generalize these results to a situation where people are spending prolonged periods of time indoors together.”” https://www.nytimes.com/2020/07/14/health/coronavirus-hair-salon-masks.html

  15. Do you have a video on cleaning masks? Is leaving them on the dashboard in a closed car in the sun for several days adequate to kill the virus? Do the various UV light boxes or wands work for sanitizing masks?

  16. I have a question, Dr. Gregor. I bought some face masks with two layers of cotton material and a pouch in between where you can slide something for extra protection. One thing that was recommended was a coffee filter. Are you saying that this type of set up is not effective, or just that using coffee filters alone is ineffective.

  17. Im an an operating room RN and expecting the public to safety use masks and not contaminate themselves, others and the environment is a joke. They are Unsafe and increased Risks Viral Transmission have a look:

    The WHO confirms that masks carry uncertainties and critical risk including
    – increased risk of self-contamination due to handling the face mask and subsequently touching the eyes with contaminated hands
    Despite educational efforts by health authorities on proper mask use, As RNs we observe rampant misuse of masks in the community. We see masks that are stored incorrectly, reused, worn around chins or with noses exposed, repeatedly adjusted and discarded to litter our streets. I have yet to see anyone sanitize their hands after touching their mask.
    Masks harbor contaminants capable of causing serious illness if they are handled, stored or disposed of improperly. Considering that people touch their faces 15-23 times on average, it is extremely unlikely that laypeople, especially children, can master the near-aseptic technique necessary to avoid contamination. Even among trained medical personnel contamination by the incorrect removal of masks is a persistent problem. As a case in point, even under the threat of Ebola the biggest contamination risk is the way masks are removed. ( an no Dr Gregor they dont make you more aware, in fact the Pelzman principle says that people take MORE risks when they feel something is protecting them)
    Dr. Teresa Tam, Canada’s Chief officer of Health confirmed this: “Even in a hospital setting, we find that it’s removing personal protective equipment that can actually lead to infections.” (Please see Appendix A for other officials’ statements on this matter.)
    Dr. Jenny Harries, Englands’ deputy chief medical officer, told BBC news:
    “What tends to happen is people will have one mask. They won’t wear it all the time, they will take it off when they get home, they will put it down on a surface they haven’t cleaned. “Or they will be out and they haven’t washed their hands, they will have a cup of coffee somewhere, they half hook it off, they wipe something over it.”
    “In fact, you can actually trap the virus in the mask and start breathing it in.”
    Asked if people are putting themselves more at risk by wearing masks, Dr Harries added:
    “Because of these behavioural issues, people can adversely put themselves at more risk than less.”

      1. What is that logic Deb? have you read the WHO’s report? Again, they are a geopolitical organization run by a sociopathic billioniare.
        I know EXACTLY what the WHO says on this and its entirely contradictory.
        Lets review it kay?
        The World Health Organization also confirms that masks “offer a false sense of security, leading to potentially less adherence to other preventive measures such as physical distancing and hand hygiene.”
        The June 5 WHO guideline (pg 7-8) discusses the benefits and risks of universal masking. The guideline lists numerous risks of healthy people wearing masks, but sparse benefits other than “reduced potential exposure risk.” The language also indicates the benefit of universal cloth masking is to collect data and that universal masking is an experiment. If this is indeed an experiment, under international law of the Nuremberg/Helskini agreement, consent must be voluntary and study participants must give permission. This is impossible with mandatory policy.
        The WHO confirms that masks carry uncertainties and critical risk including
        – increased risk of self-contamination due to handling the face mask and subsequently touching the eyes with contaminated hands
        A June 5 WHO guideline describes numerous risks of masking, including:
        • Difficulty with communicating clearly
        • Disadvantages for, or difficulty in, wearing them by specific vulnerable populations such as those with mental-health disorders or developmental disabilities, the deaf and hard of hearing and children
        – A June 5 WHO guideline states:
        “At present, there is no direct evidence (from studies on COVID19 and in healthy people in the community) on the effectiveness of universal masking of healthy people in the community to prevent infection with respiratory viruses, including COVID-19.”
        “At the present time, the widespread use of masks by healthy people in the community setting is not yet supported by high quality or direct scientific evidence and there are potential benefits and harms to consider.”

        The cite such pathetic advantages like “mask making create employment” and being “polite” Sorry baby that dont cut the mustard.
        The level of evidence is of the poorest quality I have seen for such a widespread mandate.
        Much of the support for universal cloth masks mandates is based on low-grades of evidence and studies of medical-grade masks in hospitals, NOT cloth masks in community settings. Also, high-grades of evidence such as randomized controlled trials with verified outcomes at a population level are absent.
        Dr. Michael Osterholm, Director of the Center of Infectious Disease and Research Policy (CIDRAP) has spoken out about the current flood of inadequate evidence to support the public use of facemasks. In relation to the CDC’s recommendation of cloth masks, he stated:
        “Never before in my 45-year career have I seen such a far-reaching public recommendation issued by any governmental agency without a single source of data or information to support it.”
        So do you care to tell me what GOOD evidence the laughable WHO has? .

  18. It’s the law. Most places. Some of the time. It’s about civility also. We surely do not have all the information, not yet. (Remember how recently we are being told to wipe down our groceries.) Do the best you can. I’m for more layers, like a bandana over a cloth or paper mask, or a coffee filter insight another mask. Even better, stay home, as much as you can.

  19. I am surprised to see something not mentioned…N95 masks with an easy exit valve blow the breath and germs straight out the hole!!! Therefore, can we conclude anything besides that N95 protects only the wearer and spreads germs, and that cloth/improvised protects others, and the wearer less so?

    1. myusrn,

      Chicago did a study where they tested a 90% polyester–10% Spandex fabric, and flannel and they tested a 65% cotton–35% polyester blend and other combinations and they said that they can likely provide good electrostatic filtering of particles.

  20. N95 Respirators

    (A) I have come across two different counterfeit N95 respirators in the last week. Be aware.

    (1) A friend was proud of his Internet savvy at procuring N95s off an Internet site at this time of national shortage. He claimed – patriotically! – that the masks were American-made! (I have often found defrauded people to be conspicuously enthusiastic). I was happy for him until we recently met – outside – sunny day – well-distanced – to exchange some materials. On immediate glance, there were two suggestions of likely fraud: (i) ear loops instead of headbands, (ii) a single marking of “N95” on the front with no NIOSH or other model or lot numbers. Plus the unknown brand name plus the masks’ provenance. Think about it – it is much more likely to find counterfeit N95s on the Internet during this time of national shortage rather than the genuine article, which even hospitals purchasing departments, doctors, dentists and industry are unable to obtain in adequate amounts.

    (2) A recent visit to a local regional (not national) big box store. Shelves full of unknown brand Chinese “N95” respirators – it says “N95” right there on the box. Yesireee. No NIOSH approval on the box. No valves. Why might the latter raise suspicion? N95 masks sold in big box stores have always been for trade use and industrial use, not medical use, and generally have exhaust valves for better toleration of long term wear in a strenuous physical environment – hours of sanding, that sort of thing. They are intended to protect the wearer from the particles, not the particles from the wearer. Valveless (medical) respirators in this setting are not typical, and should be considered with care. Should you have concerns in similar circumstances –

    ———————-

    (B) People are missing the distinction between Surgical Masks and Procedural Masks.

    To clarify:

    (1) The surgical masks that we have available have two ties that tie behind the head. They filter down to 0.1 microns. The seal to the face is much better than you see with the ear loop procedural masks – better protecting both the patient and the wearer. Breathing is less restrictive than with N95s, but slightly more restrictive than with procedural masks. You can wear them all day – or all night for that matter, ask any sleep-deprived surgical intern – with no problem. As for your nose itching – well, hey, you learn to live with it.

    And to quote a friend: “You know – sometimes it’s good to itch.” (I never could get there, but I admired his spirit).

    Prior to the introduction of medical N95 masks, medical personnel “double masked” with surgical masks while (briefly) entering TB patient’s rooms, or while bone sawing Jakob-Creutzfeldt cadaver’s skulls during autopsy (hey – I left the autopsy suite when I heard the saw hit bone, leaving the building while holding my breath, thank you). Remember: if you can smell it, you are absorbing it. Rule Cranial Nerve One. In those days, double masking with surgical masks was considered to be adequate protection for the wearer. It is only since the introduction of medical N95 masks that double surgical mask protection to the wearer has been brought into question.

    A tie-on surgical mask can actually have a pretty decent seal to the face. Not an N95 fit, but pretty good. Try it.

    (2) The procedural masks that we have available have elastic ear loops. They filter down to 0.6 microns. They make sense in the laboratory environment or a waiting room and do offer some protection to both the wearer and the people in the room. They are better for untrained personnel – clerical workers, patients in the waiting room – as they are easier to don and use. As for protecting the wearer and others – I would take these over cloth masks any day of the year.

    ———————-

    (C) N95 Respirators.

    The only time that I have seen N95 respirators in use in a medical setting prior to the current crisis has been in dealing with TB (Tuberculosis) patients. Physicians, Nurses and Radiologist Technicians in the hospital – briefest possible encounters. Never in surgery. In my mind, these were always intended for short term wear – not for 8-12 hour ER or ICU shifts or for the OR.

    Oh, yes – in 2003 during the SARS crisis. But that’s another story.

    For longer-term wear, I find valved NIOSH approved N-95s with an overlying procedural mask to be the preferred combination.

    You mileage may vary.

    ———————-

    (D) Brand names:

    The brands of Medical N95s that I have seen in the Hospital Supply Catalogues over the decades have been 3M and Moldex. Nobody else.

    I have been responsible for the purchase of both. People have tended to prefer the fit of the 3Ms, but faces and fits differ. And, to be fair, the different masks come in a number of different sizes – Moldex, particularly – and we did not buy all the sizes available.

    When – if – this is all over and you have the opportunity and the wisdom to stock up for next time, I would start with genuine 3M and Moldex respirators purchased from a reliable source – not Amazon or eBay, but directly from a long-established medical supply company. 3M and Moldex know what they are doing. And consider paying for a professional fitting session with someone with the training and equipment and experience to do it right.

    As for surgical and procedural masks, we have been more than happy with Mölnlycke.

    ———————-

    (E) I have been at this for decades. Responsible for the purchase of PPE from a time before it was called PPE – and the supervision of those using it. I have knowledge. I have experience.

    I view people who question the usefulness of medical masks – whether they claim to be nurses or physicians or Ph.Ds – or dogs on the Internet – to be sincere but misguided.

    I would dismiss their writings out of hand.

    Silly. Flat Earthers. Screw loose. Lights may be on, but no one is home.

    Not even worth wasting a moment of time in engaging in discussion.

    Feel free to waste your time with them if you like – but you really have better things to do.

    Like counting a loved one’s freckles.

    I come up with a different number every time . . .

    If one of these people ever showed up in one of our operating rooms insisting on not wearing a mask because they have it all figured out because they read some studies – we would throw them out of there so fast their heads would be spinning. Employment would be terminated – no discussion. “Get out! Now!” Quickly forgotten, except as a warning story about how deluded – and dangerous – some people with a tiny itty bit of a nibble ofknowledge can be.

    But it has never happened, and it never will.

    ———————-

    (F) Wear facial protection – for your sake and for the sake of those around you.

    As they are available to you: N95 > Surgical Masks > Procedural Masks > Cloth Masks > Niqab > Whatever.

    Do what you can. For yourself and for others.

    Yours in health –

  21. Hopefully we will ALL have n95 masks soon.

    Now we are using awful masks that are very poor performers.,leaking around the nose,chin and sides . The leaks reduce filtration by 50%.as shown by the American Chemical Society testing in the April issue of 2020 in the ACS journal

    It is possible to mimic an n95…..using tightly woven cotton with an inner filter of polypropolene fabric sandwiched in the middle (like MERV 13 or FILTI fabric)……and it is easy to breath through.There are hundreds of patterns on the internet with a cuplike raised center that will fit test. We should be aiming for the best alternative…..until our n95s are available.

  22. Quick update from an American urban hospital ICU:

    (1) The earlier African American intubated ICU Coronavirus patients have now largely been replaced by Hispanics. No one I know of predicted this – I certainly did not. The ICU nurses’ explanation: the African American population has gotten the word, and is wearing masks. The Hispanic population is late to the party. The nurses message to you: wear a mask! Wear a mask! Wear a mask! It works!

    It’s really very, very simple. You could teach a child to do this.

    Their message: wash hands, social distance and wear a mask!

    If you don’t get it – you may well get it.

    My added thoughts – the general population will not wear masks with the care and wisdom of educated and trained medical personnel – of course – they will make many obvious blunders. Some will be downright idiotic in their behavior. But in this case – perfect is the enemy of good. Something is a whole lot better than nothing.

    I think this comes close to proving how well masking works. On a population-wide basis. If you need any more proof.

    Close enough for me, anyway.

    ———————-

    A few other minor notes from the ICU:

    (2) The nurses are quitting – leading to understaffing – leading to more nurses quitting – leading to more understaffing. I believe that you may see where this is heading.

    I am under the impression that it is the more experienced nurses who are quitting first.

    The wiser heads.

    Leavin’ the young’uns to fend for themselves.

    My note – I predicted this back in February – I am surprised that it has taken this long to happen, here – at least, I have not seen such reported in the media. You see – this sort of thing happened in 2003 (SARS). In 2003, it is my understanding – correct me if I am in error – one Toronto hospital hit with SARS had the same thing happen – “You can fire me if you want – I’m not coming in.” Not one person – the staff. They had to close one of the affected hospitals – they couldn’t staff it.

    I wasn’t there – these are just stories I picked up at the time.

    Note bene: nurses never ever ever signed up to be heroines. That is a media and societal fantasy. The phrase you may have heard a few months ago in the media, the gung-ho “This is what we signed up for!” – I have never once heard from one physician or nurse of my direct acquaintance. Not once. It is entirely a media fantasy construct. Nurses are ordinary, reasonable, decent people with real lives and real life expectancies who signed up to fall in love, get married, have kids, and have a career helping people – or whatever. Considering the circumstances – whatever they decide to do – I wish all of them all the best in living their lives fully and in optimal health.

    When this hit New York HARD – New York could just pony up and import more nurses from the hinterlands. But all the travelling nurses are now up to their elbows in work at high hazard pay (well deserved) in Texas, Arkansas, and Florida. There just aren’t many other trained and experienced ICU and ER nurses sitting idle, ready to hit the road.

    This is going to get . . . interesting . . . dontcha think?

    (3) Convalescent plasma is not working. It’s not working. It’s not working.

    (4) ICU ventilator patients are now in the ICU for two months. Two months. This is unheard of.

    (5) ICU ventilator patients are being discharged either to nursing homes or to the morgue. Two months on a ventilator – stiff bodies – no muscle left. Human bodies were never designed for this. No one is walking out.

    (6) Lotsa neuro issues.

    You do not want to get this stuff.

    Not now. Not later.

    You do not want to give this to anyone.

    The ICU nurses want you to wear masks.

    Listen to them.

    Wear a mask.

    Good night,

    1. Vivamus,

      You mentioned the Hispanic community and I had been reading a study where they looked at deaths and with the deaths, 34.9% of Hispanics and 29.5% of nonwhites were people who were under 65 years old.

      In the USA, 20% of the deaths have been people under 65 years old.

      So the Hispanic and nonwhite communities have a much higher risk of dying younger than the whites in the USA. Though, I think they said that the whites still had over 13% of the deaths were people under age 65.

      Those numbers may change soon because Texas and Florida have started having elderly populations affected and Texas looks like they might have something similar to what happened in NY nursing homes, but race is such an important risk factor.

      1. Deb,

        A caution about focusing on numerical death rates.

        Or on any statistic at all.

        The use of proning, anticoagulants and steroids – and other interventions – may be extending coronavirus patient life.

        On ventilators.

        From three weeks to over eight weeks.

        Thence into nursing homes instead of into caskets.

        Statistically, it looks like everything is getting better. Fewer deaths!

        The patients aren’t dying! Yay!

        Look at the graph of the improvement! Most dramatic!

        But the reality is – have we really done the patient any favor at all?

        Are we really avoiding death? Or are we just making death last longer?

        When you focus on death rates – you can miss the reality on the ground.

        Suggestion: get your nose out of the literature and into the wards.

        Touch reality with your own hands.

        Smell it.

        Shhh . . .

        Listen –

        Look around you.

        Otherwise you may miss the mark entirely.

        All the best,

        Vivamus

        1. Vivamus,

          Of all of the people that I know who have died from COVID-19 so far, none of them were in nursing homes or wards of any kind.

          They were younger than that and should have had decades of good life ahead of them and they were well-loved with young children and families who did not want them to go.

          20% of the people are younger.

          Over 30% of the people are younger in nonwhite communities.

          Even my elderly relatives and relatives who are older with vulnerabilities are doing everything they can to stay alive and they do not want to die and are not close to death.

          I do have relatives who do have extreme health problems, but what I see is that all of them are wanting to be alive and they are trying to do what it takes to stay alive and independent.

          I have been down this road plenty of times and even the one relative that I had who had said that he would rather die than go on dialysis a few years ago, has been on dialysis for a year now and he is desperately fighting to live.

            1. Deb,

              Of course I am not saying anything of the kind.

              Don’t be ridiculous.

              If you think that I am, you are wildly leaping to some extraordinarily bizarre conclusions.

              Put a lid on it.

              We all understand the disproportionate effect of the Coronavirus on the elderly, those with co-morbidities, and various ethnic groups.

              That is basic. Elementary. Epidemiology 101.

              Understanding that does not label such people “expendables.”

              I am concerned that one can get lost in statistics and lose sight of what is actually happening on the ground.

              That is also Epidemiology 101.

              Focusing only on newspaper articles’ statistics can lead to less – not more – understanding at times.

              Particularly – focusing only on mortality statistics without concurrent understanding of morbidity – which may be much more widespread and which does not lend itself to easy newspaper statistics – may be misleading.

              When “recovered” in the official statistics does not mean fully recovered in any reasonable sense.

              The best way I know to understand the coronavirus is not by simply looking at graphs and charts and quoting statistics but by being there or by connecting with people with direct knowledge of patient care.

              Statistics are a helpful tool – but they can be misleading of themselves. Everyone trained in science has this drilled into them from day one. I.e.:

              “There are three kinds of lies: lies, damned lies, and statistics.” (popularized by Samuel Clemens writing as Mark Twain).

              It is important to gather the statistics – of course – but the interpretation – and the possible pitfalls of the interpretation – are key.

              For example – here’s a simple one:

              Coronavirus mortality is disproportionately associated with decreased serum Vitamin D.

              Erroneous conclusion – we should go take vitamin D to ward off the Coronavirus.

              Reality: the elderly have lower vitamin D levels than the rest of the population and the elderly are more likely to die from coronovirus. So – low Vitamin D is just a marker of a high-risk population, with no proven cause-and-effect relationship. People with darker complexions – of various ethnic groups – produce as much as 5X less vitamin D per unit of sun exposure as people with lighter complexions. They have lower vitamin D on a population-wide basis – and are at higher risk on a population-wide basis. But no proven cause-and-effect relationship in relation to low vitamin D actually increasing mortality may exist. So – low Vitamin D may be entirely a marker of more vulnerable populations than a cause and effect relationship, and no recommendation to take Vitamin D can be made from the association. Correlation is not causation. Statistics 101

              Careful of getting wrapped up in statistics.

              It is not the statistics themselves – we all have access to the same statistics. It is what you do with the statistics.

              At the beginning of all this, Vietnam had access to the exact same statistics that the U.S. had.

              Vietnam has had no Coronavirus deaths. Not one. The U.S – as of this writing – 138,000.

              Vietnam understood the statistics it was facing – and took the correct action. The U.S did not understand, and did not take the correct action. And here we are.

              Statistics are an important first step. But they are just the beginning.

              It’s what you do with them.

              Vivamus

              1. I sure do agree with you about statistics. My eyes and ears glaze over when somebody rattles off various stats about a subject (including nutrition).

                And don’t get me started on those fake poles.

      2. Do relative rates of obesity, hypertension, vitamin D status and socioeconomic status affect the vulnerability of people under 65? That is, those risk factors may be the real issue rather than ethnicity per se.

  23. The airports/airlines are fascinating to me. The fact that the TSA agents are so infected likely means that COVID-19 is all over the airports and we have daily flights (which Dr. John C. pointed out months ago as not being good) but the planes have improved filtration and now they are requiring people to wear masks.

    So, in all of these months, there have been so FEW airplane cases and yet, there have been so MANY TSA cases.

    What are the TSA agents doing differently than the people traveling?

    I would guess that would be where it would be that they handle people’s property? But I thought they have people open it themselves.

    It is hard to believe that those huge airports aren’t more protective than airplanes.

  24. I looked up what TSA agents do at airports and it makes even less sense unless the lounge in the airport is where they are spreading it.

    This was their job description:

    Loading cargo,
    Screening baggage,
    Protecting exits
    Searching people – so that could be one, but the people would have masks on and the people would be more likely to get it from them, from the numbers I am looking at.
    Giving directions and responding to inquiries.
    Identify and locate potentially life threatening or mass destruction devices, and to make effective decisions in both crisis and routine situations.
    Engaging in continuous development of critical thinking skills, necessary to mitigate actual and potential security threats, by identifying, evaluating, and applying appropriate situational options and approaches.

    This may include application of risk-based security screening protocols that vary based on program requirements.

    I think they must not be applying the risk-based security screening protocols when they go in the airport lounge after work or something.

    It genuinely doesn’t make sense that the planes aren’t getting inundated with cases and the people looking at the screening machines are.

    1. It’s like sexually transmitted diseases perhaps. The more sexual partners you have, the more likely you are to contract an STD.

      A TSA officer might have to stand in close proximity to thousands of travellers every day. The rest of us might only have to stand in close proximity to a few dozen different people every day, probably fewer, depending upon our personal circumstances.

      Those figures don’t seem at all surprising to me.

      1. Tom,

        Yes, that is one theory on my list, but airplanes used to be one of the worst for spreading things like viruses and they have almost contained it to the point where with all of these flights and all of the confirmed COVID-19 with the TSA people, there are so few transmissions on the plane. When they say 3 people, that means basically someone sneezed in one row or something like that.

        Whoever did airplane safety did enough.

        Whoever is in charge of the TSA didn’t bring in something like having people stand in front of cameras for the facial recognition or some extra measure. It might be lunch at the airports or bathrooms at the airports.

        They missed something and haven’t corrected it yet.

        Kudos to the airlines though because they have done something special to have the low level of transmissions that they have.

        1. They might be a specific group where better masks could help them or face shields or plexiglass or cameras or UVC lights in the lounges.

          Seems like I want the person who fixed the airplanes to talk with the TSA people.

          They would be an example where a better mask might change things entirely.

          There is discussion about whether teachers can have medical masks in the USA in the fall.

          It is time to triple the production of N95 masks, I think.

  25. The only thing I see other than lunch at the airport would be that they have to lift up the peoples’ masks to verify their identities, and that should be done behind plexiglass.

  26. If the 1000 TSA agents got it from that lifting the mask to show identity process but the people flying didn’t get it because the TSA agents wear masks that would be my kind of mask study.

  27. From the JAMA Internal Medicine journal earlier this month

    ‘Question Did more all-cause deaths occur during the first months of the coronavirus disease 2019 (COVID-19) pandemic in the United States compared with the same months during previous years?

    Findings In this cohort study, the number of deaths due to any cause increased by approximately 122 000 from March 1 to May 30, 2020, which is 28% higher than the reported number of COVID-19 deaths.

    Meaning Official tallies of deaths due to COVID-19 underestimate the full increase in deaths associated with the pandemic in many states.’
    https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2767980?

    This is not the story that all the YouTube ‘experts’ are telling us is it?

    1. Thanks, Tom!

      I hope there will be more hospital masks studies because so many of them were low in PPE and then they got some so we get a natural before and after line.

    1. Dan C,

      I got to the “communist” versus “racist” comments and the fact that they believe that Russia may be doing cyberterrorism on the COVID vaccine research and the fact that nonwhites are dying more and dying younger, there might be some fascinating truths hidden within the comedy.

    1. Deb, Is CNN still pushing the Russia hoax? I thought that was settled a couple of years ago. Then again, I didn’t read the whole article at the link you posted :-(

  28. Hi everyone.
    Our latest lockdown project has been to start a new WFPB discussion forum for fellow NutritionFacts fans!
    If you’re interested, head over to >> https://nutritionchat.net/
    It’s early days, so take a look at what we’ve done so far. If you like it (and see the potential) do sign-up and make your first comment (… or if you don’t like it, do let us know!)
    Comments and suggestions welcome. :-)

    1. NutritionChat.net, you do not say who you are. The menu does not contain an introoduction or information about you. The tiny portion at the bottom of the page also reveals nothing. No transparency.

      Also, the fact that you are not directly connected to NF but used similar colors and formatting is off-putting to me. You want a sign-up and ask our email but again, we have no info about you. No thanks.

      1. Hi Barb. Thanks for the feedback :-) And yes, I understand what you mean.
        There is no introduction about ‘me’ cos I am just like you … a Dr Greger fan wanting to spread WFPB ideas and knowledge. That’s it.
        And the color choice is similar, being a site to discuss NutritionFacts ideas exclusively, in a structured way, with interactive features.
        Yes, email addresses are used to protect against spam, to preserve unique identities, and to send alerts for new comments (if desired). Email addresses are invisible to site admin, and you can use a social media account if preferable.
        If you see this reply … if the site colors were updated, and guest comments enabled, would that be sufficient to tempt you into taking another look?

        1. NutritionChat thanks for clarifying what you’re about! No need to change your colour scheme… it is attractive. Just wasn’t sure if you were a commercial enterprise ‘borrowing’ the NF theme. The comments section here at NF used to take a similar form a few years back. We signed in to make a comment, and disqus indented ongoing discussions making them easy to follow. A monitor kept things on track, and prevented text flooding by any individuals. All good… the forum was a real asset to NF and participants alike. Best wishes with your site NC, and with engaging discussions to come!

      2. It might be where those here who object to “tinfoil hat posts and anything off topic and unrelated to nutrition” would take their annoying butts.

        1. Hehe … yes YR, you could well be right on this occasion too. Although I would hope not …
          One big frustration with the comments system here at NF is that the wealth of interesting and useful topic discussion is split across many different videos. Plus the latest video seems to be a general chat area for a few days, till the next video is posted.
          I’ve been mostly lurking on these pages for several years, and occasionally posting (accidentally under 2 different names!) And I was volunteering some time back to help NF with their photos.

          1. I did try to sign up. I didn’t receive an email after filling out the registration.

            Maybe it will come later.

            I just mostly wanted to encourage you in what you are trying to do.

            1. Deb, I filled out the registration page, and clicked on “register” , and I got right in to view the topics. I will check email later for password etc.

              They have done an enormous amount of work. The site is well organized, great line up of topics to get started, and looks like very useful info gathered up conveniently. I am intrigued. My hat is off to the designers/founder. Good job!

              1. Thanks so much for your support, Deb & Barb. A warm welcome to my first 2 signups. :-)
                And thanks for your words of encouragement. I’m a team of 1, making websites for charities and small businesses.
                Any suggestions or improvements, make post or drop me an email via the link (bottom right of website).

        2. Alternatively, you might consider taking yourself, your tinfoil hat, your catty remarks and your batty personal beliefs there instead?

          This is a site about nutrition facts and science. Despite your best efforts, it is not intended to be a site about astrology, weird New Age nonsense or party politics. At least, the last time I looked it wasn’t.

          1. I knew I didn’t construct that post correctly. Yes, that’s precisely what I meant…..MY annoying butt and etc..

            Some people just “don’t fit in,” do they! And so be it. :-)

            We’ll leave the catty remarks solely to you, Father Fumbles. They’re your specialty.

            1. YR, It looks like Fumbles still hasn’t realized that there can be other opinions besides those of the Authorities. What ever happened to the concept of “diversity” … of thought that is ;-)

              Science is not all just “facts”. It also requires interpretation into a consistent model, preferably one based on mathematics. And interpretations of facts can vary widely. If it weren’t for brave people like Galileo, who defied the model espoused by Authoritarians, we would still be thinking the Earth was flat.

              1. “There are in fact two things, science and opinion; the former begets knowledge, the latter ignorance.”
                ― Hippocrates

            2. Darwin (who said Americans don’t understand irony?)

              Looks like you don’t realise that some random ignorant crank’s opinion is not equally as valid as an evidence-based analysis.by world class scientists.

              If it wasn’t for people like Galileo we’d still be dominated by the opinions of religious nutjobs who reject observed facts because they don’t fit their preconceived opinions. How you can try to appropriate Galileo to support ‘imaginative’ and counterfactual beliefs is beyond me. I have to admire your brass cojones. And YR’s for that matter.

            3. YR

              My remarks are usually more shirty than catty it seems to me but whatever.

              I’m pretty sure though that you revel in being ‘special’. A bit like John Newall in fact – although admittedly you do seem much more grounded and a paragon of sweet reason in comparison.

              Not that I want to offend you either. After all, it wouldn’t surprise me if you were behind poor Lonie’s apparent ascension since you predicted it so confidently (I hope he’s OK but it’s been a few weeks now).

  29. People here seems to be more interested into themselves than into the health of people actually having COVID-19, who are badly treated in hospitals by the reductionist allopathic medecine.

      1. YR,

        Just look at the following photo shot in an hospital: while the COVID-19 patient silently suffocates from the internally increased viral pressure caused by the wearing of a source control mask (surgical mask), nurses, on the other way, seem to only be concerned with themselves and their own protection, by putting hand sanitizer onto their gloves.

        https://www.sciencemag.org/sites/default/files/styles/article_main_image_-_1280w__no_aspect_/public/ma_0424_NF_Pathology.jpg

        It is a good photo that shows a lot of what is going on with this sanitary crisis: patients are forgottten and fear is mainstream.

        1. It might not be hand sanitizer the nurses are dealing with in the photo, but in any case, they are not doing right by letting a surgical mask on the face of the COVID-&9 patient.

          The source control mask act as a “pressure cooker”, building up the viral pressure within the patient’s organism through auto-contamination within the mask.

          Source control masks are the ideological method of restricting virus propagation at the detriment of the health of patients.

        2. ab, that is not hand sanitizer, and it looks to me the patient is wearing oxygen support something like a cpap machine under the mask. It isn’t just a nasal canula, there is a black strap showing. He/she is not suffocating under the mask. Your perceptions and judgements are off (as mine may be also).

    1. ab,

      <>

      Have you better ways of treating coronovirus pneumonia patients than oxygen, proning, anticoagulation, steroids, antivirals and supportive care?

      The world wonders.

      Vivamus

      1. Yes, first of all 1) dietary cholesterol abolition as cholesterol favors the infection of cells by SARS-CoV, 2) fat reduction for the same reason, 3) plant foods rich in nitrates that favor endothelial function and endothelial nitric oxide production, an essential respiratory gas and natural anti-SARS-CoV agent, 4) red berries which contain a SIRT6 activator inhibiting cholesterol crystal formation, and finally photobiomodulation in the far-infrared which also promotes endothelial nitric oxide production.

        But don’t bother, no one wants to listen to this.

          1. And when the patient who’s O2 saturation is in the upper 90’s only on 3L nasal cannula and then within a matter of 2 minutes goes from that to O2 in the 50’s and they are being coded – what would you do then?

            1. It is not much what you do but what you do not do which is important.

              If you give O2 to a patient with an already impaired lung tissues like the ones of COVID-19 patients, you are going to increase lung injury with a severe oxydative stress caused by abnormally high levels of O2 which will further precipitate hypoxemia and possibly very quickly as you mentioned.

              Like I said in the a post above: “Eggplant is a good medical model for the pulmons of COVID-19 patients. Cut an eggplant in half and you will understand why oxygenotherapy is not a good thing for COVID-19 treatment.”

              It is a very rapid reaction: oxydative stress takes place in seconds when the eggplant tissue is not protected by its skin… The same goes for lung tissue whose antioxydative mechanism is impaired by the viral infection.

              As documented by the so-called “happy hypoxia” in some COVID-19 patients, respiratory distress is not firstly caused by a decrease in serum oxygen levels. It is firstly caused by a decrease in endothelial nitric oxide, which is prevalent in COVID-19 risk factors and also in old age. Nitric oxide is indeed needed for transporting oxygen into the cells via the hemoglobins (Premont et al, 2020) and has antioxydant properties that protects from oxydative damage caused by oxygen (Hummel et al, 2006)

              So one wants to counteract endothelial dysfunction and promote endothelial nitric oxide through correct plant nutrition, and protect the epithelium via nasal breathing, which can be complemented with photobiomodulation that can “acutely increase” endothelial nitric oxide production (Park et al, 2013).

              1. ab,

                So – you have a patient coding in front of you – he is going to be dead within moments without intervention –

                And you write an order for dietary to feed him eggplant.

                Extraordinary.

                Just – extraordinary.

                I think that your understanding of patient care may be more limited than you realize.

                All the best,

                Vivamus

                1. Your ironic statement says a lot.

                  Where do your patient come from ?

                  He comes from a consecutive chain of bad healthcare treatments beginning from public health advocates and their half-truth advices, then
                  from the general practitioners, hospital doctors, nurses, etc…

                  No wonder why your patient is dying in front of your eyes.

                  1. An obese African American male with multiple co-morbidities.

                    Co-morbidities brought about largely by poor lifestyle choices. Smoking, diet, alcohol, lack of exercise.

                    You know – the usual.

                    None of which have been encouraged upon him by the healthcare system.

                    All of which the patient has been well aware of – but has been unable/unwilling to correct despite being encouraged to do so – being a typical human in his particular eddy of modern American society.

                    Surrounded by temptations to make poor choices. Constant advertising. Family. Friends. The norms of the portion of modern society in which he lives.

                    It is not the Clinician’s place to judge him for who he is or what he has done to himself or what he could have done better.

                    Nor is it the Clinician’s place to judge the medical care the patient has received in the decades prior to the time that he has encountered the patient.

                    It is the Clinician’s place to move heaven and earth to keep him alive in the NOW.

                    Race. Sex. Age. Religion. Education. Personal responsibility. Societal responsibility.

                    None of those enter into the immediate equation. Someone is dying.

                    The Clinician does all he can.

                    And is not just a single Clinician.

                    It is a Team effort.

                    That is what a code is all about.

  30. To Mask Or Not To Mask? That is the question.

    Here is probably the best research I’ve found on the subject so far. What makes it so good is that they measure more than just the masks permeability. They measure it the way humans actually wear it, with gaps!

    https://pubs.acs.org/doi/suppl/10.1021/acsnano.0c03252/suppl_file/nn0c03252_si_001.pdf

    In “Figure S4” they show the effect of a N95 & surgical masks without AND with gaps. If it isn’t a tight fitting respirator mask there will be gaps.

    We are interested in the 100 nanometer (0.1 micron) range as that is the size of the virus we want to block. It shows as “10^2” on the diagram.

    As you can see the cloth masks are pretty much useless. Even a N95 non-respirator mask, which is as good as it gets, drop to about half its effectiveness with gaps. Also keep in mind the difference between aerosol and droplet. Before you are sick you are exhaling mostly aerosols. Once you are sick you transition to more droplets (a wet cough). If you are sick stay home.

  31. TRM,

    Great find and yes, it’s beyond revealing how we are engaged in a low efficiency approach to reality. Is there a better option short of a hepa filtration setup with supplemental air intake…. that’s both practical and affordable ?

    Clearly having a loose fitting setup is far less than appropriate. You might appreciate this article at: “I can’t see your face and more, masked from the COVID frontline” at https://pureliving.com/masked-covid/.

  32. According to an opinion piece from 3 Harvard-system hospitals, published in JAMA online on July 13, “the balance of currently available evidence suggests that long-range aerosol-based transmission is not the dominant mode of SARS-CoV-2 transmission” (doi:10.1001/jama.2020.12458) and “The balance of evidence…seems inconsistent with aerosol-based transmission of SARS-CoV-2 particularly in well-ventilated spaces.” The authors believe that at least for non-medical workers, cloth face coverings – that block droplets going out or getting in – are sufficient for most of us. Prolonged close contact with an infectious person/people indoors where air circulation is poor may pose greater hazards (“An exception may be prolonged exposure to an infected person in a poorly ventilated space that allows otherwise insignificant amounts of virus-laden aerosols to accumulate.”).

  33. I haven’t seen any data wrt paper towels. The paper is hydrophilic but porous. I expect a couple of layers would catch droplets pretty well.
    It’s easy to fold a couple of paper towels and hold them together with small bulldog clips and rubber bands.

  34. I came across this one and it has a very interesting item.

    https://www.researchgate.net/publication/342198360_Association_of_country-wide_coronavirus_mortality_with_demographics_testing_lockdowns_and_public_wearing_of_masks_Update_June_15_2020

    Do check out “Figure 1” on page 18.

    Masks by day 15 make a huge difference. Masks by day 16-30 have some effect. No masks or masks after day 60 (where we are) forget about it.

    This assumes the mortality numbers are arrived at and accounted for consistently from country to country which we know is not the case. Even if (big if) you accept that they are comparable that ship has sailed for the us as we passed the 60 day point a quite a while ago.
