This person doesn't deserve your attention. he's either dumb, jealous or very mean. This is just plain insensitive and disgusting.

Sometimes being open and telling them you were hospitalized and that they're being rude, intrusive can disarm people like this. Pretentious people don't want to look like the douches they really are in front of others.

I'm one to put people who do this kind of **** up against the wall. If you're worried at someone's health condition (some people try to justify with this) this is just no way of showing you care.
