To be clear: Masks work for some diseases and in some circumstances, when worn properly they can protect against large particles being spread from an infected person to other people. When trying to use them in widespread fashion, against the coronavirus, they do not work. Why not? The particles are too small and pass through the masks easily, even when properly worn, and they are not properly worn by the general public.
They are basically meaningless unless you experiencing symptoms (coughing, sneezing) which produce large particles the mask can catch before spreading. But if you're not showing those symptoms but are still contagious, the particles you are shedding are too small for the mask to stop.
It's just medical theater.
