The rules about masks seemed to be enforced unevenly (I think they knew I had been tested and was negative). They were men and women, from all over the world: if I were told to wash my hands thoroughly and use disinfectant, I did. In every case, when a nurse or nurse's aide or some other health professional came to my room, I totally deferred to their instructions.
I've recently spent several weeks in a couple of different hospitals for various problems: broken bones, vitamin deficiencies, and (eventually) acute depression.
I sort of feel like I live in some kind of science-fiction world.
