Tanzania has confirmed a new case of Marburg virus disease in the northwestern Kagera region, following 25 negative tests. Dozens of individuals remain under observation as the government works to contain the outbreak.

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 says one sample from a remote northern part of the country has tested positive for Marburg disease.

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.

Tanzanian President Samia Sululu Hassan confirmed an outbreak of Marburg virus after its health ministry had previously denied the spread.

A case of the bleeding virus Marburg has been confirmed in Tanzania, a week after authorities denied there was an outbreak. The deadly illness similar to Ebola is highly infectious, and can kill up to 88% of people without treatment.
