Look, masks have a role to play, but it is idiotic to think that simply because someone who tests positive for covid pulls his mask down and therefore will infect everyone he talks to. The virus isn't that contagious, not nearly as contagious as the flu (time for a flu shot by the way), and that's a fact. Especially outside, the virus is not as contagious. I'm not saying don't wear a mask, I do and you should, but it is really a tiny bandaid on the problem. Further, and most important, even if you test positive for Covid you may not be contagious. It depends on how much virus you have. If your positive result did not happen until the end of the cycles, like after the 30th cycle (and American labs spin either 37 or 40 cycles), then you are not at all likely to get sick and you are not contagious. Between 30 and 50% of positives come after the 30th cycle and are counted as "cases", even though they are almost meaningless. (It is true that a tiny fraction found after the 30th cycle might have just started to contract the virus and therefore could be sick and could be contagious, but it's too complicated to go further with this.)
