Current situation
In Rwanda
- On Sept. 27, 2024, the Rwanda Ministry of Health reported cases of Marburg in the country, including cases among healthcare workers. Illnesses have been associated with hospitals in Kigali.
- As of November 29, 2024, Rwanda has recorded 66 illnesses and 15 deaths from Marburg. CDC is working with international partners to obtain the latest case counts and will update this page if new cases arise. The Rwanda Ministry of Health maintains a webpage with case counts for this outbreak.A
- Approximately 75 percent of patients with Marburg have recovered. No new cases of Marburg have been identified since October 30, 2024.
- Marburg outbreaks are declared over if no new infections arise during the 42 days after the last recovered patient has tested negative twice by PCR separated by 48 hours. The Rwanda Ministry of Health has begun this 42-day countdown. If no new cases occur during the 42-day countdown, WHO and Rwandan health authorities could declare the outbreak officially over on December 22, 2024.
- Contact tracing and testing efforts continue. In addition, trials with an investigational vaccine are underway in Rwanda via the Ministry of Health, with a focus on healthcare workers.
- Most of the people infected have been health workers, particularly those who worked in intensive care units. CDC continues to work closely with in-country partners to help enhance infection prevention and control in healthcare facilities.

What CDC is doing
- CDC has had a presence in Rwanda since 2002, when CDC established an office there. CDC is providing technical support to the Rwanda Ministry of Health during the Marburg outbreak, while continuing to address other global public health priorities.
- CDC has deployed several scientists to assist Rwanda with its investigation and response to Marburg. CDC staff are applying their experience from responding to outbreaks of Marburg and similar diseases in other countries to help strengthen surveillance in healthcare facilities, provide technical assistance for monitoring and supporting recovered patients, improve infection prevention and control in healthcare settings, strengthen laboratory biosafety and biosecurity, develop areas of technical support in ecology studies and laboratory efforts.
- CDC is raising awareness of the outbreak with healthcare providers in the United States, including the latest guidance for them to be aware of the potential for imported cases and what to do if a patient is suspected of having Marburg.
- CDC has information and recommendations for members of the public, including people living in Rwanda.
- In Rwanda and across the region, CDC continues to engage with its domestic and international public health partners and with other U.S. government agencies to support Rwanda's response, share information, and help ensure partner countries are ready to respond if Marburg spreads across international borders.
CDC and its partners across Africa work together to monitor disease, ensure local laboratories can test for various diseases, train local laboratory and public health staff, investigate illnesses, and advise on treatment practices and how health workers can protect themselves while treating patients.
