Karl, I have no idea where you would look for it, or even if it was published. My Micro professor in college in the early 80s said that on review, it was decided that the face masking in the surgical suites was because doctors/nurses turned their heads when they needed to cough, and the droplets ended up on the floor. But even if the masked surgeons turned their heads to cough or sneeze, their germs were already entrained on the fibers of the mask, and, thus, that every breath drafted germs onto open wounds.

@Shadowmask, "So...if some company wants to be an asshole, the whole covid crap might not be over for some folks?"

Maybe. Compliance under duress is not consent. Some of these folks might be sitting on 7 figure plus retirement settlements.
