Tanzania has firmly denied a new Marburg virus outbreak in its north-western Kagera region, refuting reports by the World Health Organization (WHO). The Marburg virus, known for its deadly and highly infectious nature, has raised alarms after WHO suggested possible cases. However, Tanzanian authorities confirmed all suspected cases tested negative, emphasizing the country’s preparedness in monitoring and controlling diseases.
WHO Raises Alarm
The WHO reported nine suspected cases of Marburg in Kagera over five days, including eight deaths. This raised fears of a resurgence following Tanzania’s first outbreak in March 2023, which claimed six lives. On Wednesday, WHO Director-General Tedros Adhanom Ghebreyesus warned of potential further cases as surveillance improves in the region.
Tanzania Responds with Assurance
Tanzania’s Health Minister, Jenista Mhagama, countered these concerns, stating that laboratory analyses ruled out Marburg virus infections. She reaffirmed the government’s commitment to transparent communication and emphasized strengthened surveillance systems to address potential health risks effectively.
“We assure international organizations, including WHO, that we will keep them updated on any developments,” Mhagama said, highlighting the country’s readiness to handle health emergencies.

Understanding the Marburg Virus
The Marburg virus, similar to Ebola, causes severe illness with symptoms like fever, muscle pain, vomiting, diarrhea, and, in some cases, death due to extreme blood loss. On average, the virus has a fatality rate of 50%, according to WHO data. Transmission occurs through contact with fruit bats or bodily fluids of infected individuals. Currently, there are no specific treatments or vaccines, although clinical trials are ongoing.
Regional Risk of Spread
Kagera, a significant transit hub bordering Uganda, Rwanda, Burundi, and the Democratic Republic of the Congo, poses a high risk for disease spread. However, WHO assessed the global risk as low, stating there was no need for travel or trade restrictions with Tanzania.
Despite the denial of an outbreak, WHO emphasized the importance of vigilance, noting that healthcare workers and other patients were under observation in the region. Rapid response teams were deployed to investigate suspected cases and contain any possible spread.
Tanzania’s Previous Experience
Tanzania’s first encounter with Marburg in 2023 lasted nearly two months. The outbreak, concentrated in Bukoba district, led to swift containment measures that prevented further escalation. This experience has bolstered the country’s health response capacity and reinforced its readiness to manage future health threats.
Broader Context
The recent reports come amid heightened sensitivity to regional health risks, with neighboring Rwanda declaring its Marburg outbreak over in December. That outbreak infected 66 people and claimed 15 lives.
Moving Forward
Tanzania’s proactive denial of a Marburg outbreak reflects its focus on maintaining public confidence and international cooperation. The government’s emphasis on disease surveillance, coupled with WHO’s regional engagement, highlights the ongoing efforts to safeguard public health.
As health authorities remain vigilant, collaboration between governments, international organizations, and local communities will play a crucial role in addressing potential health emergencies and ensuring regional stability.
