When I visited Japan it wasn’t uncommon to see people wearing a simple face mask when out and about because in Japan (and other Asian cultures) when you are sick with the cold or flu. In Japan it is polite to wear a mask when you are sick and out in public so you don’t accidentally pass it on to anyone else around you. That is something I wish we had in American culture (how many times has someone given you their cold because they weren’t wearing a simple face mask?) but I really hate that we have to go through a deadly global pandemic to adopt it.
As of April 7, 2020 the United State Centers for Disease Control (and well as the Governor of Ohio) recommends that everyone wear a cloth face covering when out in public. The idea behind wearing a face mask in public is not what a someone yelled at me for falling for “pandemic panic” or a “false sense of security.” My reply was just as less than kind because I'm battling an allergy related sinus infection that never seems to end and don't want to pass this misery to anyone else (unlikely but I get horror looks when I sneeze with and without the mask.)
The idea is that by wearing even a simple, non medical grade cloth face mask when you are in public is so you may be less likely to unknowingly pass a virus to someone else when you aren’t showing symptoms and don’t know that you are sick. This precaution leaves the medical grade and N95 filtering face masks and respirators to our front line COVID 19 heroes who need to be protected from known viruses in the air around them in a front line setting.
