Just read this:

Pretty good article from someone who would be called an expert in most circles. Warning: he does bash Trump a little bit though the article isn't particularly slanted towards one party or another.
Another thing. I have long felt that N95 masks were probably reasonably effective at preventing exposure through the mouth or nose. Why else would China, South Korea, etc have an entire population doing it if it weren't. The epidemiologist here confirms my belief. It is not 100% effective (which he acknowledges) but it is not an insignificant amount of protection. I always felt the powers that be saying they are not effective was more a measure to prevent hoarding and free up masks for medical personnel. Which again, he acknowledges is the correct thing to do.
Anyway, those who want to, give it a read. I found it informative and have meant to watch Contagion for a week or two now (he was a technical adviser for the movie). Everyone try to keep your heads up.
