      1. ab,

        Two of my relatives developed pneumonia in November. They didn’t die.

        But we had what I would have called the most contagious flu season ever – people in my family were sick Thanksgiving, Christmas, and New Years and they had the dry cough and fever back then. So did many of the Starbucks workers near me. I didn’t get it. But so many people around me did get it.

        I know that I had talked about what a doozie this cold and flu season had been.

        Not saying it was COVID-19, but I am not in Italy or California, but I do mentally have an end of November with a question mark for my community.

      1. My point is that the SARS-CoV-2 may not originate from a wild animal in a wet market. It most likely originates from domesticated animals.

        The virus has “Bird flu” and “Bovine Immunodeficiency Virus” characteristics. The only way it may have gather some of those characteristics from recombination and cocirculation within domesticated animals is from animal meals or by-products used in intensive animal agriculture.

        Such sterilization under pressure is not legally enforced for those animal by-products in Europe, and mere pasteurization may not be sufficient to prevent the spread of viruses in vivo.

          1. The closest bat data is very different (4% of total genetic difference), while the pangolin is even more different (8 to 15% of difference) compared to SARS-CoV-2. The pangolin’s spike protein was close but not the whole genetic data.

            There is no way that the virus suddenly jumped from a wild animals to a human in a wet market, where animals do not stay long…

            Such mutations leading to SARS-CoV-2 take time and also need high density of animals and an environment favorable to viral recombination, like weak cells letting viral RNA entering into them via transfection, or cocirculation of viruses. This suggests that the origin of SARS-CoV is livestock and not wild animals.

            Also it has been identified that civets, pigs, pangolins, cats, cows, buffalos, goats, sheep and pigeons have a similar ACE2 receptor which could be used by the virus:

            Pigs and cows are clearly not wild animals…

            Industrial animals are fed with other animal by-products like “processed animal proteins”, whicch are big business worldwide and also a “soup of viral RNA” (even pressure cooked) that may favor viral recombination further down the line of the food chain.

    1. Even the surgical mask performed better with stockings in their study: Testing showed that it went from blocking out 75% of small particles to 90% with the addition of a pantyhose overlayer.

        1. Dr. J.,

          I led my banker to go WFPB today.

          It is going to get easier with the meat plant issues.

          She started the WFPB part of the conversation by talking about COVID and the meat plants came up and she made a joke, “We are all going to have to go vegan pretty soon.”

          To which I had a well-timed response and she said that she really would look it up.

          1. I have the thought that I could have that exact same conversation with person after person making the same joke over and over and over again.

            Things go better if they bring that part up.

    1. Thanks, Marilyn,

      I appreciate it.

      I bought Nattokinase probably out of not being able to process the blood clot information.

      I tend to cycle on and off aspirin – using Dr. Greger’s risk/benefit data.

      It seems to me that now and again in the autumn will be “on” again.

      But, you will have me learning about Vitamin E.

      I went back and looked at the last hints you gave me about the NAC and I saw some fabulous studies.

      I appreciate you.

      1. Deb, I appreciate you! You are such a kind person, even when others are not.
        The study you posted yesterday on NO in black Americans was a good one also. Thank you.
        Hopefully we are here to help one another, and you do.

        1. Marilyn,

          You are such a blessing.

          You are going to cause me to tear up.

          I have such a desire to help people and only wish I could do more.

          I look at you and you are doing it.

          I wish I had known how to become someone who could really help.

  1. My friend was asking me today for advice on air purifiers versus ionizers.

    I have medical grade purifiers myself, but I saw this ionizer and they had independent testing data with things like viruses and I was impressed by some of the study information.

    I am still wondering if it is really safe. I read a meta-analysis, but that would have had me say not to bother, but the study results here intrigue me.

  2. Masks are going to be an amazing topic after this pandemic.

    People who are wealthy have been able to buy high tech options like this

    Plus, there are masks already that are antimicrobial and antibacterial and that are made in ways to lower bird flu viruses for about $35. It is a multi-use mask.

    Also, more companies like IQ Air are selling masks from their filters.

    They are more expensive, but they are closer to the N95 equivalent.

    10 for $69.

    1. I do not recommend wearing masks once symptom onset. Self-isolation for protecting others, but source control may be deadly.

      To wear a mask after symptom onset may increase one’s risk of aggravating the viral infection through reabsorption of millions of viruses that are within the mask.

      1. Thanks, ab.

        I will look that up.

        They are recommending that you wear it to protect others.

        I found make infused with silver, masks infused with salt, masks infused with zinc and copper.

        I am an essential worker.

        We do have people take 2 weeks off with symptoms, but there would even be hospital waiting rooms to wear them in. Plus, people are asymptomatic.

        I could make masks of my silvertize cloths or of the Silver-infused pillows.

        I wonder if adding salt and Zicam would kill it quicker?

        I have a young friend who is in a mental institution and there are 30 people on the floor and one tested positive.

        The patients get one surgical mask which is kept in a paper bag at night.

        We are sending a homemade mask and will be soaking it in saline.

        I don’t know if they will let him wear it but what he has isn’t going to be effective at all.

      2. Ab,

        Do you have studies on that?

        I ask because of the young man in the institution and people whose relatives are in nursing homes.

        People on their floor testing positive.

        1. Mask as self-protection are useful, but after symptom onset, they may be detrimental to one’s health as source control.

          Just look at the studies showing how viruses can spread into the air in the supermarkets via coughing, and now, imagine that all those viruses stay into the mask of the sick patients who breathe into them, and reabsorb all those viruses into sane parts of their lungs…

          That’s why self-isolation of patients and good ventilation of buildings is preferable to source control.

          I think the risk is best documented on health professionals who have been contaminated and who wear masks all the day.

          Like, Liu Wenliang: who died from COVID-19

          “On 8 January, Li contracted the coronavirus when he came into contact with an infected patient at his hospital.

          On 12 January, Li was admitted to intensive care at Houhu Hospital District, Wuhan Central Hospital,[25] where he was quarantined, treated,[23] and tested for the virus several times until he tested positive for the infection on 30 January. He was diagnosed with the virus infection on 1 February.

          According to a colleague, Li’s condition became critical on 5 February. On 6 February, while Li was on the phone with a friend, he told the friend that he was having trouble breathing and that his oxygen saturation had dropped to 85%. At around 19:00, he was sent to the emergency room.” (wikipedia)

          He might have survived if he was not wearing a mask just after the first symptoms between the 8th and the 12th january.

          Apparently, all the sick people in China were given a surgical mask.

      3. Ab,

        I have these cloths

        And I have pillows that hospitals use that are infused with silver.

        I am offering them to the mask making person.

        I found real masks being tested that are infused with silver.

        I know mentally that I go overboard and I already want to soak the silvertize cloth in saline and spray it with Zicam and the copper ions I saw on Etsy.

        I am trying to mentally figure out whether any of the other things will help the silver work faster.

        One of my best friend’s son’s life may be on the line.

        1. Just noticed that silvertize raised the price of their cloths.

          And that they have introduced a line of masks and gloves.

          They say that it kills most things in one or two minutes.

          1. The gloves are something like $14.50.

            Now, it would make more sense putting their gloves on for 2 minutes than buying their hand sanitizing cloths.

    2. Deb

      You need to be careful with these products.

      As far as I can see, the infintebarrier mask is only effective against bacteria. Nowhere do they say it is effective against viruses. Viruses are usually much much smaller then bacteria so an antibacterial mask might well be of no use against covid-19.

  3. I found the BioMask information and it said:

    The product features a hydrophilic plastic coating on the outer layer made with citric acid. The inner layer is treated with metal ions such as copper and zinc.


  4. Today, I watched Cheryl Ladd showing children from places like Haiti where the children really had zero food half the time. Sometimes the mothers would tell them, “Today isn’t your day to eat.” The kids were filled with parasites and the water was filthy and the mothers would boil the water and make coffee as the only meal of the day.

    Thinking about the panic shopping and the potential global food shortage – those children before this were seriously filled with parasites and had only black coffee for dinner and it was probably old grounds.

    When we were young, they would say, “Eat your food, people are starving in China.” and at a certain age, I got too smart for my own good and would argue that my eating all my food wasn’t helping them at all. But I throw out packages of blueberries and could have re-grown all of the produce I threw out.

    And they don’t have any seeds or fruit or vegetables to re-grow or the internet to figure out how to do it.

    I am going to get better at this by next year and I will be growing things so I can give more money to good causes like this one.

    Most of my money this year went to things like steam cleaners and UVC lamps and UVC cabinets and UVC wands and masks and sanitizing gloves and goggles and microfiber cloths and silver-infused cloths.

    I was all about me this year, but the goal is to do this as a “once and done” and then be really able to help people.

    Getting there.

  5. Hello, Dr. Greger and everyone else who watches the videos on this website.

    I really appreciate Dr. Greger’s work in the field of nutrition and health, so I am asking a question about Dr. Greger’s DIY hand sanitizer recipe.

    On April 15, at the start of a media press briefing, the WHO announced the release of a document that stated that alcohol does not protect against SARS-COV-2. However, your DIY hand sanitizer recipe includes alcohol. Is there another substance that is more effective than alcohol that can kill SARS-COV-2? What types of alcohol should my family use if we wish to make this hand sanitizer? Thank you for your time.

    Vinay Kalva

    Link to full press briefing on April 15:

    1. Hi, Vinay Kalva! Thanks for sharing this link. I think that the comment on the video may refer to taking alcohol internally. The most effective ways to protect yourselves against SARS-COV-2 are self-isolation and frequent, thorough hand washing with soap and water. If you and your family are able to stay home, you absolutely should. Even the best hand sanitizers are second best to washing hands with soap and water. Viruses are not, technically speaking, alive, so it is not really possible to “kill” them. They are basically bundles of genetic material encapsulated in fat. The key to deactivating them is to dissolve the fat. Alcohol will dissolve fat, which is why most hand sanitizers are alcohol-based. You may be interested in these resources, if you have not already seen them: I hope that helps!
