Difficult to prove that masks helped, difficult to prove masks didn't help.And probably more difficult to prove that masks increased infection rate as well ... I don't buy this masks harbour viruses so are likely to increase spread of the virus. If you are infected yourself, then you aren't going to re-infect yourself, and the mask will surely reduce the amount of virus you are breathing out in airborne droplets, and if you say that the masks pick up the virus that's contained in the airborne droplets breathed out by other people, so they are hanging around for longer, I'd suggest a high proportion of those droplets would have been inhaled by you directly if you weren't wearing a mask.I could be wrong of course, and maybe masks do make things worse, but there seems little credible evidence around. Coincidence and causality are two very different things.
