"A handful of ecologists knew for years that West Africa was at risk for an Ebola outbreak. Now they're figuring out where else in the world the virus could be hiding. Many signs point to Asia."

"A few years ago, disease ecologist David Hayman made the discovery of a lifetime.

He was a graduate student at the University of Cambridge. But he spent a lot of that time hiking through the rain forest of Ghana, catching hundreds of fruit bats. ...

Bats carry a huge number of viruses in their blood. When Hayman took the blood samples back to the lab, he found a foreboding sign: A high level of antibodies against Ebola Zaire."
