Neil Orr showed us in 1981 that a mask, surgical mask etc., wearing one, actually causes infection to the surgical field; no doubt, issues around type, shape, whether facial movements etc.

This simple elegant study showed us over 40 years now that the masks don't work and cloth masks are junk.
“It would appear that minimum contamination can best be achieved by not wearing a mask at all but operating in silence…. The finding that there was an appreciable fall in the wound infection rate when masks were not worn certainly warrants further investigation. This trial was designed only to see whether wound infection increased, as had been predicted, when masks were not worn. It did not. The conclusion is that the wearing of a mask has very little relevance to the wellbeing of patients undergoing routine general surgery and it is a standard practice that could be abandoned.”
