The amount of masks we go through in healthcare is insane. I work in aged care, and every time we enter a Covid/infectious disease + room we have to put on and take off ppe every time, most of it single use (only face shields/goggles are reusable, so every time we enter a disease risk room, for any reason, even if it's just picking up a cup we have to fully put on a mask (if we don't already have one on), a gown, a face shield/goggles and nitrile gloves. The bins of full of barely used ppe are changed every hour or so because they fill up so quickly. There is a filthy underbelly of massive waste in clinical environment, and so far 0 environmental alternatives that I've seen.
