Personal protective equipment. Gloves, mask, goggles, gown, booties, etc. Depending on the hospital protocol and congeous rate, you would have to suit up with plenty prior to entering the patients room and take it all of prior to leaving so that whatever contaminated the ppe stayed in the room. It use to be frowned upon wearing your mask everywhere because you were seen as taking all your germs around. Last time I worked in any Healthcare was in 2016 so things have changed.
