I'm not opposed to cooperating with more masking out of hand, but I do wonder how effective it is, and what the evidence looks like. I know the support initially for just using any mask at all was predicated on the idea of spread primarily happening via droplets. I believe we now know that the virus is shed and spread by much smaller particles, and I doubt cloth masks or poorly fitted medical masks help much with that. I have a giant box of KN95s that I used in some settings, and I often feel air moving in and out around the sides, and they fit pretty well. I don't want to go through the whole exercise if it isn't actually doing anything useful. [edit] I'm not sure what people are opposed to here. I am as I said happy to comply with public health measures that work and are supported by evidence.
