Nine cases of the deadly disease have been reported in the Kagera region of Tanzania so far. But officials expect that number to rise.

Tanzania has pushed back against a report from the World Health Organization warning of a new Marburg virus outbreak in the country.

Tanzania's government said no-one in the country had tested positive for the Marburg virus after the World Health Organization (WHO) said at least eight people in the northwest were believed to have died from it.

In March 2023, Tanzania reported its first Marburg virus outbreak, which also occurred in Kagera region. The outbreak was declared over in June 2023, with nine infections reported, six of them fatal. The WHO said zoonotic reservoirs of the virus, such as fruit bats, remain in the area.

Marburg virus disease, caused by a virus from the same family as Ebola, has a fatality rate of up to 88% without treatment.
