Tanzania’s government announced that no confirmed cases of Marburg virus have been detected in the country, despite a World Health Organization (WHO) report suggesting at least eight suspected deaths in the northwest due to the deadly virus.
“As of January 15, 2025, laboratory tests for all suspected individuals were negative for the Marburg virus,” Health Minister Jenista Mhagama said in a statement issued late Wednesday.
The WHO had earlier reported receiving credible information about suspected Marburg cases in Kagera region on January 10. The affected individuals reportedly exhibited symptoms consistent with Marburg, including high fever, severe headaches, vomiting blood, diarrhea, and external bleeding.
Deadly Viral Disease
Marburg, a viral hemorrhagic fever related to Ebola, has a fatality rate of up to 88%. The virus is transmitted to humans from fruit bats and spreads through direct contact with bodily fluids, contaminated surfaces, or infected individuals.
In response to the suspected cases, Mhagama said the government immediately deployed experts to Kagera, conducted investigations, and collected samples for testing.
Tanzania previously experienced its first Marburg outbreak in 2023, recording nine cases, including six fatalities, in the same region.
Improved Preparedness
The health minister emphasized that the country has since “strengthened disease surveillance systems” to respond swiftly to potential outbreaks.
Tanzania faced international criticism during the COVID-19 pandemic for withholding data and failing to implement preventive measures. This time, Mhagama said the government is prioritizing transparency and preparedness to reassure the public and international health partners.
The WHO has yet to issue an updated assessment on the situation following Tanzania’s announcement.
