How about they don't be self-centered pricks and accept quarantine instead of risking infecting thousands of people. Getting around quarantines like that should be highly illegal. The guy was a doctor, he should have known better.
Yeah, good luck with that. So many of the world's problems could be solved if only people would stop being self centered jerks! And then we could all link arms and sing Kumbaya!
These cases of doctors/nurses traveling even after exposure are particularly egregious, but human history is literally a case study in self centered and thoughtless behavior, "screw you i got mine" mentality and other related, unpleasant human traits. Why can't we all just get along??
