Marburg Virus Origin: What Do We Know?
The Marburg virus is a highly infectious pathogen responsible for Marburg virus disease (MVD), a severe form of hemorrhagic fever. First discovered in 1967 during outbreaks in laboratories in Marburg and Frankfurt, Germany, and Belgrade, Serbia, the virus was linked to African green monkeys imported from Uganda.
The natural reservoir of the Marburg virus is the Egyptian fruit bat (Rousettus aegyptiacus), which carries the virus without showing symptoms. Human infections occur through exposure to infected animals or direct contact with bodily fluids from infected individuals. The virus primarily impacts sub-Saharan Africa, with outbreaks exhibiting high fatality rates depending on the quality of medical interventions.
Marburg Virus Disease Outbreak: Latest News
In 2024, Rwanda reported its first outbreak of Marburg virus disease on September 27. With 62 confirmed cases as of October, it is the third-largest recorded outbreak, primarily affecting healthcare workers. The government, supported by the World Health Organization (WHO), has launched rigorous containment measures, including infection prevention training, PPE distribution, and public awareness campaigns.
WHO highlighted that the outbreak poses a very high risk nationally and a high risk regionally, although the global threat is considered low. Ongoing efforts include active case surveillance, the setup of treatment centers, and clinical trials for experimental therapeutics.

Marburg Virus Symptoms
Symptoms of Marburg virus typically manifest 2 to 21 days after exposure and progress in three stages:
- Early Stage:
- Sudden onset of fever
- Severe headaches
- Muscle pain
- Progressive Symptoms:
- Nausea and vomiting
- Severe diarrhea, often bloody
- Abdominal cramps
- Severe Symptoms:
- Hemorrhaging from gums, nose, and other sites
- Organ failure and shock
Given the overlap of Marburg disease symptoms with other illnesses like malaria, accurate laboratory testing is critical during outbreaks.
Marburg Virus Treatment: Is There a Cure?
There is no definitive cure for the Marburg virus or antiviral treatment. Supportive care remains the primary method of managing the disease, focusing on:
- Rehydration therapy
- Blood transfusions to manage hemorrhaging
- Treating secondary infections
In response to the Rwandan outbreak, WHO and other partners have initiated clinical trials for experimental therapeutics, marking a significant step forward in combating Marburg virus disease.
Marburg Virus: What Does WHO Say?
The World Health Organization classifies the Marburg virus as a Risk Group 4 pathogen due to its high mortality rate and lack of licensed treatment. WHO emphasizes the importance of preventive measures such as:
- Avoiding contact with bats and primates in endemic regions.
- Enhancing infection control in healthcare settings.
- Conducting community awareness campaigns to encourage early reporting of symptoms.
WHO also provides technical support for surveillance, case management, and the implementation of treatment protocols. For WHO’s official guidance, visit their Marburg virus fact page.
