Why is contraction of the virus implied as a necessary condition for being a hero? Clearly the heroic act is the treatement of others; that the hypothetical AIDS doctor or these ebola doctors contracted the disease they were treating in others should not be a necessary condition for considering them heroes.
Sure. It seems in the U.S. that all you have to do to be a "hero" is enlist in the army.

I wouldn't have been in Liberia in the first place, but if I had been, I would've been on the first plane out as soon as I even heard a rumor about an Ebola outbreak. He could have--the U.S. is aggressive in helping American citizens evacuate from situations like that. The fact he stayed and helped is what makes him a hero.
* ideal world, left or destroyed (no matter the reason): he was living a confortable life in a developed country; whether you consider the catastrophy to be his departure or his discovery of the epidemic, both match;
* his actions have to be taxing, unexpected, foster his personal qualities and changed the hero's perspective: taking care of patients with a hemoragic fever is very daunting; he didn't come for that and had to learn how (from what would be the 'Fairy godmother' secondary charater, presumably an expert either local doctor or on hemoragic fevers); he didn't go there to catch the fever anyway;
* his goal must be clear and positive (aka the Princess, or the Treasure) and be slightly different than expected, to match the hero's own change: cure Ebola, or reach good health in the area; maybe have people die in dignity; he ended up being not a carer but a patient, too; might need a little more detail, but that part is pretty well covered;
* resolution must be positive (not necesarily for the hero who may die, but for the world): we have a known process to adress Ebola (with Western-grade medecine) and still the story not over (the 'and had many children' part, obviously 90% of the story, one where being a hero but not part of the narrow frame that makes a hero): we still need to eradicate the desease.
I would say his experience fits squarely within the heroic framework.
