Not Worth Much

As I understand the science, the COVID-19 virus is smaller than the pores of ordinary masks. That is why medical researchers who work on the virus wear full protective suits as was pictured in the post "What Stops Coronavirus" immediately proceeding this one. These are one time use suits that cover everything head to toe and are discarded and destroyed after lab work on COVID-19. They cost up in the hundreds of dollars each. Even with this precaution, there is sometimes a defect in the suit or human error that causes trained professionals exposure. Obviously, laymen can not afford and do not know the proper deployment of personal protective equipment of the type that would largely block the virus. The non-medical masks many are wearing do absolutely nothing to slow the spread of the Novel Coronavirus, but may instill false confidence in the wearer that they are somehow protected when they are not.
