Im aware of n95 effectiveness. I study this subj a lot (c19). Then, it would follow govmnt should make them mandatory?

Here's a few additional items to ponder:

1) c19 has spread in homeless population. Yet nearly none get seriously ill. That's interesting.

2) prison populations continue to report high attack rates. Yet, have extremely few serious cases or fatalities

3) south Korea controlled their in-hospital c19 transmission without extreme PEP measures. What they did do is impose strick hand washing protocols. Entry/exits any room, and after touching any possible infected person or surface
