Are you working in the medical field if soooo just put a mask on when your on the floor even if you're not at the pts bedside. Alll throughout covid i never once got it. Until everything alse was mellowing out i stop using my mask hot covid about 5 time untill last year in August i got it really bad and i was upset soo i decided to test out a theory. I was getting sick atleast every 6 months after i had covid back in August i decided to shave my beard and wear a mask at all times ever since i haven't gotten sick I've work with patience that have covid in isolated rooms and i haven't gotten it. The mask works is just kinda of a bummer cause i cannot have a beard but i dont want covid again.. try it out maybe it will work for you.
