Scientists have discovered Marburg virus in fruit bats in Sierra Leone. This is the first time the deadly virus has been found in West Africa. Five Egyptian rousette fruit bats tested positive for active Marburg virus infection. Scientists caught the bats separately in three health districts: Moyamba, Koinadugu and Kono.
The virus was found in advance of any reported cases of illness in people in Sierra Leone, and there remain no reported cases of Marburg in humans there. However, the virus’s presence in bats means people who live nearby could be at risk for becoming infected with Marburg virus, a cousin to Ebola virus that causes similar disease in people.
