In 2024, the first case of Marburg virus disease (MVD) occurred in Rwanda, which was reported to the World Health Organization on 28 September 2024.[2] A total of 66 people were infected during the outbreak, 15 of whom died, with the majority of cases occurring among healthcare workers, particularly those working in intensive care units.[2][3] Rwanda has had one of the lowest Marburg mortality rates on record – while in previous outbreaks as many as 88 percent of those infected died, in the Rwandan case it was about 23 percent.[3] The outbreak was officially declared over on December 20, 2024, after 42 days of no new cases.[2] Rwanda's swift and effective response included mass testing, contact tracing, and the launch of a clinical trial of a Marburg vaccine.[3] The risk to the European Union and the European Economic Area was considered low because transmission of the disease was limited to three clusters of cases – one familial and two caused in healthcare facilities without shared community transmission.[4]
