Ebola Arises Again and Again by 'The Editors' (Scientific American)

This analysis by University of Oxford researchers of previous outbreaks shows that the death rate has been greater than 33 percent and that there is often more than one cluster of infections, typically because of sick individuals seeking treatment or traveling. Experts worry that without vigorous, sweeping efforts to identify and suppress new outbreaks as soon as they emerge, the virus will become a permanent health risk, erupting unpredictably in Africa and around the world.
