The worst thing I saw during this is that I know a professor at Yale Medical school that wrote a book on the Spanish Flu. There is an entire chapter about masks and the conclusion it had no effect on the outcome. She was calling for people to wear masks and even double mask. I then quoted her own words back to her.
