Ethiopia Investigates Marburg Virus Disease Outbreak

The World Health Organization (WHO) is assisting Ethiopia with experts, supplies, and emergency funding as the country investigates eight suspected cases of viral hemorrhagic fever in the South Ethiopia region.

On November 12, health authorities in Ethiopia are intensifying investigations and emergency response efforts following the detection of eight suspected cases of viral hemorrhagic fever (VHF) in the South Ethiopia Region. As laboratory testing continues at the Ethiopia Public Health Institute, national officials have requested international support to accelerate containment and protect communities.1 According to the World Health Organization (WHO) as of November 20, 33 laboratory tests had been conducted, of which 6 confirmed cases of Marburg Virus Disease (MVD), including 3 deaths. The remaining 3 cases are currently being treated. In addition to the lab-confirmed cases, a further 3 epidemiologically linked cases could not be tested; all three are deceased and recorded as probable cases. A total of 206 contacts have been identified, and contacts are under active follow-up. The number of contacts will continue to change as the response evolves. The source of the infection has not yet been identified. This marks the first confirmed outbreak of MVD in Ethiopia.2

In response, WHO has deployed an initial team of 11 technical officers with extensive experience in managing VHF outbreaks. These specialists are assisting with enhanced disease surveillance, case investigation, laboratory diagnostics, infection prevention and control measures, clinical management, and overall outbreak coordination. Their involvement aims to reinforce the country’s preparedness and ensure a rapid, organized response while the source of the suspected infections is determined.1

What You Need to Know

Ethiopia is investigating eight suspected viral haemorrhagic fever cases while awaiting confirmatory laboratory results.

WHO has deployed experts, medical supplies, and US $300,000 in emergency funds to strengthen surveillance, diagnostics, and clinical response.

Rapid reporting and early containment are essential due to the severe and epidemic-prone nature of viral haemorrhagic fevers.

WHO is also delivering critical supplies, including personal protective equipment for frontline health workers, infection-prevention materials, and a deployable isolation tent to strengthen clinical care capacity. Additional technical support is being mobilized as the situation evolves. 1

To enable immediate action on the ground, WHO has released US $300,000 from its Contingency Fund for Emergencies, ensuring Ethiopia has the resources needed to scale up its response while laboratory results are pending.1

In a previous interview with Contagion, William A. Fischer II, MD, director of emerging pathogens at UNC’s Institute for Global Health and Infectious Diseases, and David Wohl, MD, professor of medicine in the Division of Infectious Diseases at UNC, discuss what is like to work in a hot zone where high-consequence infectious diseases such as MVD occur.

About Hemorrhagic Fevers

Viral hemorrhagic fevers—which include Ebola, Marburg, Lassa fever, and Crimean Congo hemorrhagic fever—are caused by several virus families and can spread rapidly. Early symptoms often include fever, fatigue, dizziness, muscle aches, and severe weakness. Health authorities stress that all suspected cases should be promptly reported, even before the exact viral cause is confirmed.1

Individuals can be infected in several ways:

  • Contact with urine, fecal matter, saliva or other body excretions from infected rodents.
  • Contact with the bodies of dead infected animals.
  • Being bitten by infected mosquitoes or ticks.
  • Contact with animals that have been bitten by infected mosquitoes or ticks.
  • Close contact with infected people or their body fluids. Ebola, Marburg, Lassa fever, New World hemorrhagic fever, and Crimean-Congo hemorrhagic fever viruses can be spread from person-to-person. People can also be infected by touching objects such as syringes and needles that have been contaminated with infected body fluids.3

Hemorrhagic fevers are rare in the US, and are typically found in travelers who come back to the country from areas were these fevers are endemic or found more commonly.
