TweetI was watching something on the news where they were showing how air disperses when someone coughs/sneezes in a surgeons mask, or one of the home made ones. Instead of the air rushing forward, it just accelerated out the sides of the mask. For the people that just wear a bandana, a lot of the air penetrated it and the virus is small enough to travel through. Having to wear one actually makes me touch my face even more because I'm constantly having to adjust it, which also defeats the purpose of having it on. I see so many people doing the same thing. Touch everything in the store, get in line and sit there adjusting the mask all over their face. Then, look at me funny as I'm not wearing one having not touched my face once since I left the house.
