If one has traveled abroad to help treat--and save--victims of Ebola, one should be just as cognizant of the need to NOT infect others. If one has a problem with a 21 day quarantine, one should not put oneself in a position where one might take 21 days to exhibit contagion of Ebola: walk the walk, talk the talk, or take a hike: I don't need you to infect me, because you want to "save the world."
