Each and everyone of you arguing about everything is right to a degree. For example, it is a tough predicament when non medical personnels buy masks that nurses and surgeons need to use. Stockpile is low, but if you see Japan, a country that literally uses masks excessively had only 9 new cases vs USA that had 1500+ cases. You do the math. New England Journal of Medicine also stated if someone infected sneezed or coughed, Covid19 can stay airborne for up to 30 min under the right temp and humidity. Masks aren't a complete deterrent, but at least it will cover the front side to an extent if you use the right mask. The sides of your face will be difficult.
