Actually, it is precisely BECAUSE of controlling transmission of pathogens FROM doctor TO patient that doctors and nurses wear masks.
And yes, some people wear terrible masks, or wear them incorrectly, or don’t throw away disposable masks and regularly disinfect reusable ones. Some people also wear their seat belts wrong. Is that reason to tell everyone to stop wearing seat belts? Or should we simply fix the problem of some people doing it incorrectly?
You missed the point, doctors don’t go to work sick and wear a mask when they are breathing out virus fumes. They stay home.
With covid we are told to wear a mask to protect others, especially when we are sick, in other words we keep rebreathing bad air.
Check out these studies;
“No masks were worn in one operating theatre for 6 months. There was no increase in the incidence of wound infection.”

“MASK WIGGLING AS A POTENTIAL CAUSE OF WOUND CONTAMINATION” (now think about poor mask hygiene practiced by untrained and uneducated covid mask wearers)

“It has never been shown that wearing surgical face masks decreases postoperative wound infections. On the contrary, a 50% decrease has been reported after omitting face masks.”
“Masks may be used to protect the operating team from drops of infected blood and from airborne infections, but have not been proven to protect the patient operated by a healthy operating team.”
