Marburg virus is a rare disease that can be spread between humans via contact with bodily fluids from another infected individual. The disease is severe and in 80% of cases fatal. The virus causes symptoms such as fever, headaches, muscle aches, rash, vomiting and more. 

The virus is most commonly found in sub-Saharan Africa. Multiple countries in this region have been affected in the past, with the most recent outbreak reported in Ethiopia. Ethiopia is a country located in the Horn of Africa, with the second-largest population on the continent.

The country has already battled multiple viruses, such as yellow fever, hepatitis, HIV and more. On November 12, 2025, a new outbreak of Marburg virus was detected in Ethiopia. This strain is reportedly the same strain that had broken out in other African countries. There are at least nine cases of Marburg virus in Ethiopia, with six confirmed deaths.

The Cause

The virus spreads to humans from infected Egyptian rousette bats. According to scientists, there is an increased risk of outbreaks as “climate [instability], as well as deforestation and urbanization, is steadily destroying the habitats of the fruit bats that harbor diseases like Marburg and Ebola…” Once the virus has infected humans, it can be transmitted to others through contact with infected bodily fluids.

To prevent transmission, experts recommended that those working in or visiting areas inhabited by bat colonies take protective measures, such as wearing gloves and masks. They also advised avoiding contact with individuals who are already infected.

Treatment

Treatments and vaccines for the virus currently do not exist. However, some vaccines are under investigation and early supportive care has also been shown to improve the survival rate of those infected. Nonetheless, multiple other countries, such as Rwanda, Tanzania and the Democratic Republic of the Congo, have experienced Marburg outbreaks but managed to control the virus in a short period through several effective methods.

This was achieved through community engagement and intervention practices, such as case management, reducing the risk of human-to-human and bat-to-human transmission (through isolation, masks and other measures), surveillance, contact tracing and more. These methods may be implemented to combat the virus in Ethiopia.

Responses

Multiple responses have been implemented to aid those who were infected, prevent transmission and eliminate the virus from the country. Various health organizations have carried out these measures:

• Ministry of Health: The Ethiopian Ministry of Health has taken multiple measures to fight Marburg virus in Ethiopia. This includes establishing a National Task Force to aid in decision-making and resource mobilization, along with a three-month response plan. It has also been informing the public about the outbreak and conducting surveillance and response activities.
• The World Health Organization: The WHO has also been supporting Ethiopia during this time. The organization has deployed a team of expert responders and provided the necessary medical supplies and equipment.
• Africa CDC: Ethiopia’s molecular diagnostic and genomic surveillance capacity was immediately put to use during the outbreak. Africa CDC supported these efforts by providing sequencing equipment, PCR detection kits with Marburg-specific assays, extensive training and other resources.
