If they don't work, then why are they so concerned about nurses and doctors wearing them? My wife works in a doctors office, they do work, if worn properly, to both prevent you from spreading it, but it does reduce the odds of you inhaling it. Thats exactly why they are pushing it. you can be a carrier for the virus and not even know it. That said, the problem with masks are, most people do not know how to removed them properly and thus, they don't work to protect yourself because most people want to constantly touch the mask, therefore increasing the number of times they are touching their face. and every time they break that seal, is defeating the purpose
