My wife just came down with a really bad cold in the last 24 hours... runny nose, sneezing, sounds terrible, no energy, etc. Her work is allowing it fine as she has no fever and after contacting local PCP, they said it's fine as long as there's no fever. She's taking her temp every 3 hours or so. Will likely go home early today anyway but her spa has no employees and no one applying...so she needs to be there for now until someone comes in at noon.
But it seems like a good starting point that everyone with a head cold doesn't just get sent home for two weeks or presumed to have COVID. The fever seems to be the really big part per the hotel group's SOP and the physicians advice.
I always get at least one crushing head cold per winter...usually lasting 1-2 weeks. Maybe this enhanced hygiene though will cut down on those things like you said.
