Unidentified disease kills 15 in Tanzania

At least fifteen people died and more than 50 others were hospitalized in southern Tanzania due to an unidentified infection that caused many to experience nausea and vomit blood, health officials said on Feb. 7.

Felista Kisandu, the chief medical officer in the remote Chunya district of Mbeya city, said a team of medical experts have been deployed to clinically assess the patients and investigate the cause of the outbreak.

"This problem has not been widespread, it has happened in just a single administrative ward of Ifumbo where people vomit blood and die when they get to the hospital late," she said.

The cause of their illness has not been identified yet, but Tanzania's Health Ministry has ruled out an outbreak.


Initial clinical examination revealed the patients, mostly men, experienced stomach ulcers and liver disease, Kisandu said.

"We have advised them to avoid drinking illicit brew, smoking cigarettes and other hard drinks," she said.

Kisandu said various samples of water and patients' blood have been sent to chief government chemist for verification to establish if there's traces of mercury contamination.

According to records at Mbeya's Chief Medical Office, a similar disease plagued the region in 2018, when several people were confirmed to be suffering from high fever, stomach upset and vomiting blood.

Doroth Gwajima, Tanzania's health minister, has deployed a team of experts to assess the situation and instructed them to submit a written report establishing the cause of the disease for further actions, a statement issued by the ministry said.

The minister called on the people to remain calm while officials are making a follow-up on what had happened.​​​​​​​
