Tracking virus carrying bats in Ugandapublished at 12:11 Greenwich Mean Time 18 December 2018
The Marburg virus is one of the world's most deadly viruses; it can kill humans within a week. Scientists know that the virus is carried by bats but no one really knows where they go at night.
They say that if they knew then perhaps they would be able to work out how the virus is carried.
A group of experts are researching this by glueing tiny GPS trackers on bats in Uganda.
Dr Jonathan Towner, a virologist from the US Centers for Disease Control and Prevention, is the man in charge of the project.
He spoke to the BBC's Newsday's presenter Shaimaa Khalil.
