If by “work,” you mean “provide some limited benefit in some settings,” then that is correct.
By “work” I mean lessen the viral load. I also wear a face shield to help it along because I am not in an area with very few cases.
I ,in no way, believe wearing a surgical mask or even an n95 mask is going to keep out every single virus particle in every circumstance.
Heck, I am cognizant of the fact that I very likely will,at some point, do something wrong and take it off the wrong way or some other thoughtless action that could infect me.
My purpose is to lessen the viral load so my body can fight it off until such time as this virus mutates or they can come up with some medicine that has a good chance of working on me.
