On #1: I continued researching after the interesting evidence from parent.
To anyone interested this is an overview of multiple studies of N95 usage and it’s efficiency in stopping covid spread [1].
TLDR; The results for flu studies show no conclusive efficiency, there are no covid studies, and many studies show negative health effects of the healthy using masks; breathing in virus through nasal passage causing infection to spread where it otherwise wouldn’t, hypoxia causing lower immune response and other negative health effects, etc
