The Risks - Know Them - Avoid Them from Professor Erin Bromage a Comparative Immunologist and Professor of Biology (specializing in Immunology) at the University of Massachusetts Dartmouth. His blog has received over 15 million hits to date and he has been covered in the news. It does a really good job of explaining the risks and under what conditions your chances of exposure greatly increase. www.erinbromage.com/ post/the-risks-know- them-avoid-them 12 minutes read if you are interested In order to get infected you need to get exposed to an infectious dose of the virus; based on infectious dose studies with other coronaviruses, it appears that only small doses may be needed for infection to take hold. Some experts estimate that as few as 1000 SARS-CoV2 infectious viral particles are all that will be needed (ref 1, ref 2). Please note, this still needs to be determined experimentally, but we can use that number to demonstrate how infection can occur. Infection could occur, through 1000 infectious viral particles you receive in one breath or from one eye-rub, or 100 viral particles inhaled with each breath over 10 breaths, or 10 viral particles with 100 breaths. Each of these situations can lead to an infection. Indoor spaces, with limited air exchange or recycled air and lots of people, are concerning from a transmission standpoint. We know that 60 people in a volleyball court-sized room (choir) results in massive infections. Same situation with the restaurant and the call center. Social distancing guidelines don't hold in indoor spaces where you spend a lot of time, as people on the opposite side of the room were infected. The principle is viral exposure over an extended period of time. In all these cases, people were exposed to the virus in the air for a prolonged period (hours). Even if they were 50 feet away (choir or call center), even a low dose of the virus in the air reaching them, over a sustained period, was enough to cause infection and in some cases, death.

tinytim : That's an article about SARS just in case someone gets it confused with COVID-19 They are not the same but can be just as deadly.

Regarding all of them the key thing most articles doesn't mention is the best practice prior, is good nutrition. Less than 4% of all COVID-19 deaths were people with sufficient vitamin D levels, over 96% were vitamin D deficient. It is 100% well known fact vitamin D helps prevent Respiratory Distress Syndrome. www.ncbi.nlm.nih.gov /pmc/articles/PMC618 6338/ www.bmj.com/content/ 356/bmj.i6583

M1cha3lo0o : I've read the articles you linked and I do not see the 4% number you quote. I also do not see where any claim in either article where it states sufficient vitamin D will prevent you from being infected with the coronavirus. Is there such a claim and I am missing it?

M1cha3lo0o : I am well aware of the importance of vitamin D in general and the low levels especially for minorities in America. I was just wondering if there were any claims regarding vitamin D and the coronavirus specifically as I have not seen any studies or claims regarding that. Thanks.

M1cha3lo0o : Yeah in the article you linked, ""While I think it is important for people to know that vitamin D deficiency might play a role in mortality, we don't need to push vitamin D on everybody," said Northwestern's Vadim Backman, who led the research. "This needs further study, and I hope our work will stimulate interest in this area. " It is just an observation is how I interpret it and there has not been any scientific evidence to date to determine anything at this point. I have read this observation before and the same thing that somebody hopes it warrants further research. Thanks.

tinytim : Correct if you are not Vitamin d deficient you don't need to supplement it. If you are deficient, like 42% of america is you need to fix that problem the exact same as being deficient in any vitamin. Do you know if you are vitamin D deficient?

M1cha3lo0o : Actually I do. My endocrinologist talked to me about vitamin D deficiency about 3 years ago. Gave me a prescription then after that recommended I take a daily supplement. I take a vitamin D-3 supplement (1000 iu) with K-2 (better absorption) and have been fine since. I read a few of the articles you linked and to quote the first one. "Finally, and importantly, one must remember correlation does not necessarily mean causation."
