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

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.

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.
