Can Masks Capture Coronavirus Particles: Study done by University of Edinburg
You obviously did not read the rest of the article comment I made after you read the above statement. You missed the point completely.
The N95 or the KN95 masks that you brag about having, are worthless too against this virus. The openings in them are .30 microns. The virus size ranges from .06 to .14 microns, plenty of room for the virus to get in and out of the N95 masks.
IOW, the N95 masks don't stop the virus at all whether you wear it or someone else wears it. It gives you false sense of security and makes you feel superior to those that don't wear it.
BUT THE MASK DOES ABSOLUTELY NOTHING TO PROTECT YOU, THIS PERSON ON CHEMO OR ANYONE ELSE FOR THAT MATTER.
The only people who wear a mask that is ineffective are the "Karens" of the world who think they are being smarter than everyone else. I betcha you wear one in your car with the windows rolled up and when you are alone. You probably wear latex gloves too, which are ten times worse that just washing your hands frequently if you don't change them after you touch something while wearing them.
The local grocery story has a sign on the door that says the county requires people to wear masks to enter. I have never worn a mask in the store and never will. There's nobody at the front door stopping me. When I get in the store, not only does anybody working there not say anything to me, but many of the other customer aren't wearing masks either. And only some of the employees.
Forget your KN95 mask for "protecting" you from this virus. They are useless for that.
