If you’re in an enclosed area with someone for an extended period of time what are the odds that any mask is going to stop the virus from entering your body?
I’d guess at somewhere between zero and none. Maybe even less than that.
My simple point is if masks have an efficacy (yes, that is not proven) when it comes to viruses it is many times more likely in close contact in closed settings but not out and about in random passing fashion in public spaces.
I see individuals walking down suburb streets all by themselves and all masked up. When I see it I think herd mentality.
