It does a bit toward preventing spreading it if you already have it What you just described is the same thing, it's simply a matter of perspective. If you wear a mask, it helps me by reducing the chances that you spread it to me if you have it but aren't experiencing symptoms yet. It works the same way in reverse. I don't wear a mask to protect myself, I wear it to protect others in the case that I'm shedding virus and don't know it yet.
