On 14 November 2025, Ethiopia confirmed its first outbreak of Marburg virus disease (MVD) in the South Omo Zone, Southern Ethiopia. This outbreak represents a significant epidemiological shift: Ethiopia has never previously reported MVD. Genetic sequencing suggests the strain is closely related to East African lineages, pointing to a regional reservoir. Laboratory testing identified Marburg virus in samples from a cluster of suspected haemorrhagic fever cases. To date, 10 cases have been reported, including five fatalities (CFR 50%), two among healthcare workers, highlighting the risk of nosocomial transmission. A total of 57 suspected cases have been investigated, including four in the past 24 hours.
