In March 2023, Tanzania experienced its first outbreak of Marburg virus disease, a rare and deadly hemorrhagic fever similar to Ebola. That outbreak also occurred in the Kagera region, which borders Uganda and Rwanda.

NAIROBI (Reuters) - A suspected outbreak of the Marburg virus in northwest Tanzania has infected nine people, killing eight of them, the World Health Organization has said, weeks after an outbreak of the disease was declared over in neighbouring Rwanda.

Tanzania's President Samia Suluhu Hassan confirmed on Monday that there was a new outbreak of the deadly Marburg virus in the East African country.

Tanzania's president has announced an outbreak of Marburg virus, an Ebola-like virus, just a week after her health minister denied that there were any cases in the country. President Samia Suluhu Hassan said at a press conference on Monday that health authorities had confirmed one case of Marburg in the north-western region of Kagera.

Officials previously questioned whether the deadly disease was indeed present in the African country, which had seen 8 suspected Marburg deaths.

Tanzania’s president said Monday that one sample from a remote part of northern Tanzania tested positive for Marburg disease, a highly infectious virus which can be fatal in up to 88% of cases without treatment.
