Virus-Infected bats May Be to Blame for Ebola Outbreak


The Ebola epidemic in West Africa may have started with virus-infected bats, a new study says.

Ebola epidemics are “zoonotic” in origin, spreading to humans through contact with bats or larger wildlife, according to the researchers in Germany.

But their investigation ruled out larger wildlife as the source of the 2014 outbreak, which began in the Guinean village of Meliandou.

“We monitored the large mammal populations close to the index village Meliandou in southeastern Guinea and found no evidence for a concurrent outbreak,” said the study’s leader, Fabian Leendertz, from the Robert Koch Institute in Berlin, in an institute news release.

Bats, however, do have contact with humans in Meliandou. And one type of bat in particular — free-tailed insectivorous bats — may be a plausible source of transmission, the researchers determined.

So far the Ebola virus has killed about 7,700 people and sickened 20,000, mostly in the West African countries of Sierra Leone, Guinea and Liberia.

The study, published Dec. 30 in EMBO Molecular Medicine, was conducted by a multidisciplinary team of researchers. Over a four-week field mission in Guinea last April, the researchers examined human exposure to bats. They also surveyed local wildlife and collected sample bats in Meliandou and nearby forests.
