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'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.

The WHO said Tuesday that a suspected outbreak of the deadly Marburg virus in Tanzania had killed eight people, warning that the risk of further spread in the country and region was "high".

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

The World Health Organisation (WHO) has warned of a suspected new outbreak of the Ebola-like Marburg virus in north-west Tanzania, saying that at least eight people have already been killed by the disease.

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