An international study, conducted by researchers from the Institute for Development Research (IRD), Inserm and Institut Pasteur and their Guinean partners (Donka University Hospital, Macenta Hospital, National Institute of Public Health, and University of Conakry, confirms that Ebola virus persists in the semen of survivors of the epidemic in Guinea, for up to 9 months after their recovery. These results, which recall the importance of monitoring survivors in order to prevent the risks of new epidemic outbreaks, are published in the Journal of Infectious Diseases on 3 May 2016.
