It isn't about what *I* know. It is about what extensive scientific reporting tells me. You could take the time to read the science yourself but you won't.
Reality is cloth masks are not effective. N95/KN95 can help but we don't really know to what extent. And if they aren't used correctly a person becomes a one man superspreader.
And the surgical mask is of marginal value but may be better than nothing.
On June 20, when Fauci magically changed his mind from "Masks don't help" to "You should wear a mask" there was no new science that was relevant to that decision. Dead giveaway.
Scott Gottlieb himself has stated cotton masks "might" offer 10%, or maybe 30% protection. That's not even a vote of confidence. It is an incitement to stupid behavior.
No one gets Covid at the Post Office. We need protection when we enter a medical facility, or when people are in risk categories, or in a crowd. But anyone who wants to prevent the illness simply stays out of the crowd or wears actual mask protection when necessary.
