I don't know much (well, anything really) about disease transmission, but should these health workers not quarantine themselves away from the immediate vicinity of the infection, but before taking a cross-Atlantic/Pacific flight where they could infect a number of other people in close proximity?

I would have through the health agencies they volunteer with would enforce these kind of quarantines to prevent international transmission of disease.

On one hand I can't help admire these people risking their lives to help people on the other side of the world. On the other hand some of them seem content to play Russian roulette with their neighbors and family back home, which makes no sense to me. Is it as the OP suggested that doctors make for bad patients?
