Saliva drops are bigger than smoke particles.
For a infected person that sneeze or coughs, wearing a mask, the mask can reduce the risk of contamination with x%.
So masks are not always useless, but for healthy people, there’s no use in wearing a mask.
right. there are different masks for different purposes. a gas mask is not the same as an oxygen mask (like firefighters use). A surgical mask will not protect you from cvid only a n95 or better will.
I never said a surgical mask would prevent you from getting COVID.
But it will reduce spread.
The same way sneezing in your armpit/elbow will.
