no that's not why at all if they make a mistake they'd know who did it even without the mask they wear the mask for the same reason they sterilize their hands and wear gloves its to protect them frogetting and giving off disease there are also other reasons as well but none of them are so that people don't know who did itWhy do surgeons wear masks during operations?
Its to stop infection because when you are having a operation you are very prone to infections so the want the operating room as sterile as possible.
because your mouth and nose are full of bacteria and when your opend up your bodey is ammuno compermised which means you can get a infection real easy
No, so they don't throw up from the smell, and so blood won't go in their face.
