I have never heard of a hospital asking someone to wear a face mask when they were sick and visiting the hospital. I have never seen this in an American hospital pre-COVID.
The idea that a face mask can block anything is utterly insane. If they were super contagious, you would seal the body in a bubble to prevent any exchange, and run all the air through an advanced filtering system that can remove literally everything.
The research on masks has shown that wearing a mask doesn't limit the spread of the disease in any way, and it does cause other issues. I don't know what research you are citing, but this was a well-known fact before COVID.
