I agree that there is a piece of mask-wearing that is performative political correctness.
OTOH, properly fitted masks worn by properly trained and well-disciplined wearers saw me through 37 years of working with patients with TB, sars, H1N1, AIDS, Hep ABC, Pneumococcal pneumonia, and meningococcal meningitis without any of us contracting the diseases.

Properly fitted means having a good seal: if I have a good seal, my glasses do not fog.

And when I was really serious about safety, and working in a well-resourced organization, I wore a PAPR.

Masks can help, social distance can help, hand washing can help. None of them are guarantees.
