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.

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

Tanzania’s president says one sample from a remote northern part of the country has tested positive for Marburg disease, a highly infectious virus which can be fatal in more than 88% of cases without

Dr. Tedros highlighted the collaborative effort, stating, “WHO is committed to supporting Tanzania in bringing this outbreak under control while working toward a healthier and safer future for all.”

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.
