My question to you is did you read this? The 4th from sciencemag in particular. I like what it said about an indoor environment. And you still say wearing a mask helps? Maybe we need to all wear the hazmat suits like your article says is the ONLY way it could be contained. Pretty good article. The others said little to nothing other than about multi layer mask( which are basically ineffective) and do not much better than a single(pretty little mask) at containing the spread of anything. Maybe we should wrap our heads with bubble wrap so we can't breath instead of breathing without these mask and let it run it couse like it is going to do anyway. MASKS DON"T HELP DUDE, face it. They do little to nothing against the spread of this. YOUR articles even prove it.
