I don't think there is anyone contesting that masks help by controlling the disbursement of droplets...but IMO of all the precautions the public has been advised to heed ( i.e., distancing, don't touch face, wash hands etc., etc...)...wearing a mask is by far the least important...other than when close proximity is unavoidable...

It seems there are actually many people on this thread, and in society, contesting that masks help control disbursement of droplets, and ergo, virus transmission. I honestly don't know which one is most effective. If you know of any studies that have compared them, I'd be happy to learn. However, without this information, statements like "wearing a mask is by far the least important ... other than when close proximity is unavoidable" are wrong. The data available proves they do make a measurable difference. As previously discussed regarding aerosol spread in environments, statements like "when close proximity is unavoidable" are also misleading. Think of it like when restaurants used to have smoking and non-smoking sections. Sitting adjacent to a smoking table with a pony wall between you meant you were sitting in the smoking section. You want to think about airborne spread in terms of concentration, not distance. Concentration will decrease with distance, but if there is poor/no circulation, distance does nothing, because the concentration level continues to build up. Again, this is why if you are outdoors, and can maintain 6-foot distance (to avoid direct contact from larger droplets) then aerosolized droplets are likely not of concern.
citing all the studies has really nothing to do with the actual subject...some peeps want the public to think wearing masks is as good as a vaccine...
I would say those individuals are similarly misinformed. I've never come across a single person that has expressed that, although that doesn't mean they aren't out there. Again, the best approach to combating spread is a multi-pronged approach. Hand washing, social distancing, mask wearing, and developing a vaccine.
BTW...just curious...how many of those studies you cited are funded in by private sector entities and how many by public resources??...and finally, just who are the entities in the private sector?
Well, you could look just as easily as me. If there is funding, it will be disclosed at the end of the paper in the "Acknowledgements" section.
To save you the time, I went through all of them. As I said in a post a few days ago, the vast majority of work is federally funded. In the articles I quoted there was not a single one funded by private sector. There were: 14 that were federally funded (various countries, predominantly US), 6 with no funding (meaning they do it on their own time and at their own expense), 2 funded by their own University, and 2 funded by Foundations. Note, some were funded by multiple (e.g., federal and University). 1 Foundation was the Chan Zuckerberg foundation, I don't remember the other one, and I'm not going to go back through all of them again to find it ... I believe all foundations are considered charitable organizations.
BTW...ostriches do not bury their heads in the sand...LoL...but some peeps (or is that profs) will believe anything...:laughing:

Yes, I realize that. But in spite of that, it is commonly used vernacular to express the sentiment of someone that wants to hide and ignore the peril around them. It's called an idiomatic expression. Kind of like "a bird in the hand is worth two in the bush." I don't know of many people that are capable of catching flighted birds by hand, but it is used to express a sentiment. Trying to use that to disparage me? Well, that just reflects poorly on you.
