Consider that when people go about their daily lives they put their hands on everything in their environment; door handles, gas pumps, counter tops, store shelves, etcetera.
And I notice people constantly touching and readjusting their masks. Some people do it almost subconsciously.
I notice people wearing everything from flimsy & porous cloth masks, to bandanas and surgical masks. I even saw a guy with a full beard wearing an ill fitting N-95 the other day.
It stands to reason that when people constantly touch their masks they transfer germs to the mask with their dirty hands, and subsequently inhale the germs.
The average size of a COVID-19 virus particulate is approximately 0.125 Micron or 125 nanometers in diameter so various face coverings provide different levels of protection and some not at all.
In my opinion, masks may help, especially the immunocompromised. But they also give people a false sense of protection, and at worst, may be another vector.
We've been masking for almost eight months and we continue to see new cases daily.
