One bit I finally gleaned about masks. A suspicion is droplets contain more virus than aerosols. Droplets will settle out of the air quickly. But kicker, droplets can also dehydrate and shrink to aerosol size and persist. But they still contain the same dose of virus. Eeek! That part of why masks help prevent people from spreading. Because even shitty masks do a good job of stopping droplets. Before they dehydrate and become aerosols. Beyond theory there is a paper the showed the results of wearing masks by people with influenza, rhinovirus and common coronavirus. Result. Slight benefit for influenza. Don't work for rhinovirus. Works very well for coronavirus. I think the take away there is. Wearing masks prevents people from producing highly infections aerosols. And you should avoid spending long amounts of time in enclosed spaces with other people.
