Yeah, so this is again not why doctors wear surgical masks. Has nothing to do with viral contagion. Has to do with bodily fluids and the like. Viruses can't be stopped by wearing a surgical mask. Airflow goes up, around and through.
Yes, body fluids (like saliva and the sort). Nothing to do with viruses. No one wants the doctor to say something to a nurse and have droplets fall in an open wound.
The size of virus "particulates" is smaller than the mask. This is from breathing, and escapes the mask. Larger - more direct transfer - comes from speech (or coughing/sneezing, etc) while standing over a patient with an open would. Go look it up if you don't believe me. That is the reason for surgical masks in the operating room. No one ever (prior to COVID) said "we're wearing masks so we don't give the patient a virus".
Some viruses have to travel on droplets, this is what makes surgical masks effective. As far as for surgery and real world application, nations with higher mask adherence have shown much lower levels of Covid infection than nations with poor adherence. There’s no debate on this even if you want there to be. https://www.poverty-action.org/stud...promotion-mask-uptake-and-covid-19-bangladesh
Firstly, as I said direct transfer of water particles to open wound (from coughing, sneezing or talking over a patient on the operating table with an open wound) is what masks are used in surgery to prevent. It is not about viral risk. Viruses are not stopped from use of surgical masks. The CDC itself (prior to COVID) and the WHO said this openly. It was only after COVID that they suddenly changed 60 some years of research. And then they changed it back. There's no debate on this because its fantasy. There could possibly be some efficacy increase by using N95 masks on the whole of the population. But most of the world does not wear N95s and those paper masks they hand out when someone says "I forgot my mask" is just comical. As for nations with higher adherence vs. poor adherence, I have posted dozens if not hundreds of charts making this claim horseshit. Please have a read through the Neanderthal vs. "Science" thread. Pick any chart at all, and I'm happy to discuss the info in it.
