I think it will be awhile before I get on an elevator again. I avoid them if at all possible and take the stairs, especially in hospitals where one is unlikely to ever run into anybody else using them. I can't imagine a more benign environment for germs, viruses and unfriendly bacteria. I can't imagine stepping into an elevator at a hospital. By God if you weren't sick when you got there, you'll be sick enough when you leave.
My advice: stay off the happy vertical people movers and die like a man, climbing the stairs.
