During the days of AIDS there was a small group of Kenyan prostitutes who just never contracted AIDS.
AIDS, now ebola. There always seems to be some nasty pandemic on the horizon, doesn't there?
Yeah, shipped in straight from Africa.
I don't think it's necessarily a question of gangbuster immune systems here. The fact is, as bad as this outbreak has been, only a tiny, tiny percentage of the population of Guinea (where this kid had travelled) has been infected. Guinea has a population of approximately 11.75 million people. There have been 1,535 cases reported in Guinea - that's 0.01% of the population. Obviously the "reported" cases is an undercount, but even if the number of actual cases is 10 times the number of reported cases, it's still 0.1% of the population. When you account for the fact that Ebola is most commonly spread to caregivers (family members of patients, doctors, nurses, etc.), the odds of any random person in Guinea contracting Ebola are still remarkably low.
