You are so full of crap. NO cloth mask traps viruses. Idiot CNN bot.
Maybe you should read that again. I wasn’t talking about straight cloth masks, which, indeed, aren’t much use virus-wise. I was talking about natural cotton fibers being the best- rated material having a chance to catch anything in the virus-size range. It’s in the book. Well published long before the ceebug foofaroo. Look it up yourself. You seem to spend a lot of time on CNN?
