The primary protection a mask provides is against transmission. This is why everyone's wearing a mask is what really matters. If just one person in the room is infected, and not wearing a mask, all the others, even all wearing masks, are at risk.
First, let's set aside the imbeciles who believe that a mask provides no protection at all. Tests show that any mask at all protects against transmission better than no mask.
But which masks work best?
Without a mask, droplets from coughing may travel 12 feet.
With a bandana, droplets travel up to 3.5 feet, and with a handkerchief, more than a foot.
It turns out that a two ply fabric mask, made at home, protects quite well, reducing the transmission to just 2.5 inches. (Even the cone shaped masks reduce to 8 inches.)
So don't be shy...wear that mask, and hope that others are mindful enough of your health, to do the same!
