@yogthos@roho also, the whole point of the initial article is to explain that you don’t test masks’ efficiency via randomized trials (for the same reason you don’t test parachutes that way): though it may seem counterintuitive at first, this is actually not really a medical question but an physical/engineering one.
You need to prove that the mask effectively blocks aerosols, that it blocks transmission is then a direct consequence ;)
i dont’ think i can find the source for this one, but; there was a group doing a questionaire under people who didn’t trust the media’s perception. The outcome surprised the group. it seemed that those people having work where they have much contact with people were better of during the pandemic health wise than those having a more secluding life. ofcourse the “more research is required” clause applies.
