Why Ebola Kills Some People, Others Survive

October 21, 2014 10:29 am | by Lauran Neergaard - AP Medical Writer - Associated Press | News | Comments

People who shared an apartment with the country's first Ebola patient are emerging from quarantine healthy. And while Thomas Eric Duncan died and two U.S. nurses were infected caring for him, there are successes, too: A nurse infected in Spain has recovered, as have four American aid workers infected in West Africa. Even there, not everyone dies.
