That is stupid, you ignore a scientific study because the government pumped you wit misinformation? Early on during Covid-19 we were told masking was ineffective in slowing down Covid-19, later on we were told different. The main reason is viral organisms are much smaller than bacteria, thus the virus would still pass through N95 or even surgical masks. It turned into symbolism and the myth was created, it did little if anything, that is why large indoor events were cancelled, masis didnāt help. We need to learn and move on.
Unmasking the surgeons: the evidence base behind the use of facemasks in surgery This link addresses why surgeons wear masks, it speaks of it protecting the surgeon from infection and keep the patient safe from bacterial infections. Virus infections were not noted, probably because that is not what it was used for. The link also discusses whether wearing masks at all is effective at all for protecting against bacterial infections.
Note the article was written pre-Covid-19.
We need to follow the science, not the propaganda.
