A report published on 1 May indicates that the Ebola virus can persist in seminal fluid of a person who recovered from Ebola virus disease for longer than previously known and can potentially lead to sexual transmission of Ebola virus.

ECDC comments on two studies published on 14 October 2015 in the New England Journal of Medicine provide insights into sexual transmission of Ebola virus and the duration of virus persistence in semen.

​The risk of infection for tourists, visitors and residents of the affected areas is considered very low if proper precautions are taken, concludes the ECDC Rapid Risk Assessment on the outbreak of Ebola virus disease (EVD) in West Africa. These measures include avoiding contact with symptomatic patients and/or their body fluids, or with deceased patients and/or their body fluids. Generic precautions for travelling to West African countries also apply to preventing infections with the Ebola virus.
