The World Health Organization (WHO) has reported a suspected outbreak of the Marburg virus in Tanzania that has claimed the lives of at least eight individuals in the Kagera region. As of January 11, there have been nine suspected cases reported, leading health officials to anticipate further cases as surveillance measures are enhanced. WHO chief Tedros Adhanom Ghebreyesus stated, “We would expect further cases in the coming days as disease surveillance improves,” hinting at the potential for additional cases to emerge shortly.

The Marburg virus, which shares similarities with Ebola, can be highly fatal, with the capacity to result in a fatality rate as high as 88%. Symptoms typically include severe fever, diarrhea, vomiting, and in severe cases, bleeding from bodily orifices. The virus primarily spreads through contact with the bodily fluids of infected individuals or surfaces tainted with these fluids. This outbreak is a concerning development on the heels of a recent Marburg outbreak in Rwanda that was declared over just weeks prior, which involved 66 infections and 15 fatalities, primarily among healthcare workers.

The WHO has classified the risk assessment for the region as "high," especially given Kagera’s role as a transit hub with significant cross-border interactions, notably with neighboring Rwanda, Uganda, and Burundi. National health authorities in Tanzania have yet to officially confirm the outbreak details, but the WHO is closely monitoring the situation.

Despite the severe nature of the Marburg virus and its potential for rapid transmission within healthcare settings, WHO has assessed the global risk from this latest outbreak as low. The situation remains fluid as health teams continue their investigations, and contact tracing efforts intensify.

Historically, outbreaks of the Marburg virus have resulted in significant mortality, with the last notable outbreak in Tanzania recorded in March 2023, which resulted in six deaths. As the global health community remains vigilant, the prevention and control measures will be critical in mitigating the spread of this deadly virus in the region.
