Marburg Virus Outbreak in Rwanda: A Public Health Crisis

The recent outbreak of Marburg virus in Rwanda has raised significant alarm, marking the first reported cases in the country. As of late September 2024, health officials confirmed 26 cases, including 12 fatalities, with over 80% of infections occurring among healthcare workers. The Marburg virus is one of the deadliest pathogens known, causing severe hemorrhagic fever with a case fatality rate ranging from 24% to 88%. Given Rwanda’s limited healthcare resources, this outbreak poses a substantial threat to the country’s already fragile health system.

Understanding Marburg Virus Disease (MVD)

Marburg virus disease (MVD) is a highly infectious illness caused by the Marburg virus, a member of the Filoviridae family, which includes the Ebola virus. Initial infections typically stem from contact with Rousettus bats, but human-to-human transmission can occur through direct contact with infected bodily fluids or contaminated surfaces. Symptoms usually appear 2 to 21 days after infection, beginning with fever, severe headaches, and muscle aches, often progressing to severe hemorrhagic symptoms.

Epidemiological Concerns

The Ministry of Health reported the confirmation of MVD in patients primarily from health facilities in Kigali. Contact tracing efforts are ongoing, with approximately 300 individuals being monitored. The outbreak is particularly concerning due to the high percentage of healthcare workers affected, raising the risk of further spread within the healthcare system and to the general population.

Public Health Response

The Rwandan government, in coordination with the World Health Organization (WHO), is implementing measures to combat the outbreak. These include early case detection, isolation of suspected cases, and enhancing infection prevention protocols in healthcare facilities. As a precaution, Rwanda is receiving experimental vaccines and treatments, including 700 doses of a candidate vaccine for healthcare workers. The WHO assesses the outbreak risk as very high at the national level, emphasizing the need for heightened surveillance and public awareness to reduce transmission.

Looking Ahead

The emergence of Marburg virus in Rwanda not only poses immediate health challenges but also underscores the need for stronger public health infrastructure in the region. With historical outbreaks of MVD reported in neighboring countries, regional collaboration and preparedness are crucial to prevent further spread and protect vulnerable populations. The situation continues to evolve, and further investigations are necessary to understand the full scope of the outbreak and implement effective control measures.

Current Situation

Since September 27, 2024, the Ministry of Health in Rwanda has reported multiple MVD cases across several provinces, predominantly affecting health facilities.

CDC’s Response

The CDC, which established an office in Rwanda in 2002, is deploying scientists to assist with the outbreak investigation. They will focus on contact tracing, laboratory testing, and infection prevention. The CDC is also providing guidance to healthcare providers and the public while collaborating with local and international partners to enhance disease monitoring and response capabilities.
