In the Kagera region of northwest Tanzania, there has been a suspected outbreak of the Marburg virus, with nine cases and eight deaths reported by the World Health Organization (WHO). This incident occurs shortly after Rwanda declared control over its own outbreak of the deadly virus, raising concerns about public health in the area.
The Marburg virus, a highly infectious and severe form of hemorrhagic fever with a fatality rate of up to 88%, is closely related to the Ebola virus. Both viruses are endemic to East Africa, primarily transmitted to humans through fruit bats. The recent cases in Tanzania, emerging in a region bordering Rwanda, heighten the risk of cross-border transmission.
On January 10, the WHO received information about the suspected cases, with affected individuals showing severe symptoms such as intense headaches, high fever, extreme muscle weakness, back pain, vomiting blood, and significant external bleeding, pointing to a serious hemorrhagic condition. Samples from two patients are currently being tested at Tanzania’s national laboratory to confirm the presence of the Marburg virus. Public health officials are also tracing and monitoring all contacts, especially healthcare workers who may be at higher risk.
Rwanda’s recent outbreak, which ended on December 20, saw 66 cases and 15 deaths. The proximity of Rwanda to Tanzania’s Kagera region raises serious concerns about potential transmission between the two countries, emphasizing the need for active health surveillance. The Marburg virus spreads through direct contact with bodily fluids of infected individuals or contaminated items, highlighting the urgency of swift containment measures.
Tanzania has previously encountered the Marburg virus, with a prior outbreak in March 2023 in the same Kagera region resulting in six deaths over nearly two months. The recurrence of cases in this area underscores the ongoing threat to public health.
The successful containment of Rwanda’s recent outbreak underscores the importance of coordinated public health responses across borders. Both Rwanda and Tanzania face continuous challenges in managing infectious diseases, particularly in regions with limited and overburdened healthcare infrastructure.
To address the current outbreak, the WHO is working closely with Tanzanian authorities to determine the nature and scope of the outbreak and implement effective containment strategies. Regional cooperation is critical in addressing the emerging threat of the Marburg virus, with ongoing monitoring, public awareness campaigns, and prompt response measures essential to mitigate this alarming public health emergency.
