If none of those doctors want to accept a quarantine on the way back, they shouldn’t be trusted to be a doctor, period. If a disease can make people really sick, and you swore as a doctor to save lives with as little harm as possible, by all means, do the quarantine, I would like to see who the real doctors are, who are willi to take the inconvenience after riskin your own life.
I'd say the same thing slightly differently. If you're willing to go risk your life treating a level-4, usually fatal disease, the minor inconvenience of a quarantine on return shouldn't stop you--in fact, if you really care about people, you'd want to make sure you weren't bringing the disease back. This nurse that's going to sue is both a convenient political tool and a narcissistic do-gooder, the worst kind.
