@ DJW - the numbers aren't what I say, they are scientific facts.
"Water droplets" and "to some extent" are deceptive smokescreens used by the pro-mask supporters.
It took the W.H.O. 2 years to admit that the virus was transmitted via aerosol - not just in water droplets - so figure out how "safe" people were when shopping in air-conditioned stores, and flying on air-conditioned planes.
There was & is no scientific justification for demanding that the world's population wore flimsy, ineffectual face-coverings to limit the effects of a virus.
