Masks were a 'polite' gesture mainly precovid in Asian zones, but were never regarded as a genuine way of stopping the spread of someone's cold to those around them. The real issue is that if one person in the room is a covid carrier and exhales the virus it has to be at a high enough concentration for people to take in and have their own immune system overwhelmed. We are exposed to all manner of nasty bugs all the time but don't develop the illness because we didn't contract a high enough concentration of bugs. Now, if the carrier continues exhaling into the mask, and the mask picks up, say, 10% of the covid bugs, that is every breath. Over half an hour walking around a supermarket, that mask becomes soaked in viruses well into a concentration level able to infect and become established in somebody else. I remember interviews revealing how many times people touch their faces when this was in a true open discussion at the beginning. So the carrier touches the mask with high covid levels, picks up items in a shop or touches railings and surfaces [THAT is why the hand cleaning regime was introduced immediately], another person comes along, the concentrated virus is passed to the hands, then to the face and I remember the prime entry point to the body was through the eye sockets. But wearing the mask became an anti-trump emblem and that was that.
