The Foegen effect A mechanism by which facemasks contribute to the COVID-19 case fatality rate

Thanks for the link to the Foegen effect/study. I suspected that rebreathing virus was a bad idea; this study goes a long way towards proving it. I’ve asked what happens to droplets after they’re caught a number of times here. No one has had an answer, until now.

Thank you for all the awesome research you do.
