That feels pretty messed up. If you knew you had a communicable disease that other people might have caught from you, and be spreading it themselves, and some people dying, and you get asked "who might you have spread this to" you'd refuse to answer on privacy grounds.

I guess if you'd been to somewhere that you didn't know everyone, you'd just have to take that as an unavoidable sacrifice they're making for your privacy.
