You are a surgery outsider.I know surgeons were masks to prevent bacterial infections. But that was not my point. The virus is in the droplets we breathe, cough, and sneeze out. Properly made and worn masks help to prevent their being spewed out,, and help contain the droplets. Not perfectly,, but still they help. That is my "point."
It is rather worthless borrowing dirty masks and using them as a placebo to lead people to believe they stop a virus and ignore all the other aseptic processes applied in surgery you know nothing about.
Do you autoclave all your dishes and silverware? Use a gas sterilizer on plastics? Do you have a dressing room to change from street clothes to scrub suits when you go home and wear a sterile gown and gloves?
