Explain to me how a mask prevents the spread of COVID - 19.
You see, it works like this...the basic N95 mask that is so popular filters out nasty things down to 3 microns in size.
The Covid 19 virus is .08 to .12 microns in size....
So when a schittload of these COVID virus thingies get together-like a REALLY big schittload and attach themselves to each other ( not paying attention to nano-social distancing...) that gang of them can't get through the mask!
Simple as that!
