It's a moot point. As a nurse I can assure you that masks are minimally effective at best. Cloth masks- stop virtually nothing. Surgical masks- work solely within a sterile environment. N95 masks- stop the highest concentration of microbes yet are still quite subpar, this is way even in hospitals where PPE is extensive doctors and nurses can still be infected and commonly do. Proper hand washing/hygiene, effective distancing are more effective than masks will ever be, the mask simply allows people's minds to be pacified and lulled into a false sense of security.
