Well it could be that wearing a mask or face covering is contributing to infection. Maybe surface contamination is much more conducive to transmission. When you adjust, remove and don your mask, you increase the chances of moving some virus from your hands to your face, where it really wants to enter your system. Look at where people store their masks and how long they wear them. There is no way those things are staying sanitary. Masks are useless. If you want to reduce your chance of contracting the virus, you have to wear a full hazmat suit with it's own source of oxygen. Cases don't matter because testing is terribly unreliable, asymptomatic spread is very minimal, and proximity to someone who has tested positive is counted as a "case", so whether we have many more or not is irrelevant. Where are we on excess deaths? Time to check the stats at the CDC.
Anything is possible as many don't do things the way they're supposed to be done. Regardless, correlation doesn't necessarily mean causation obviously and that's my main point.
