"As of today, we have seven confirmed cases, of whom we have one confirmed death," Dr Kyobe Henry Bbosa, Ebola Incident Commander at the Ugandan Ministry of Health, told a briefing.
The man who died had developed a high fever, diarrhea and abdominal pains, and was vomiting blood. After initially being treated for malaria, he was diagnosed as having contracted the Sudan strain of the Ebola virus.
"But also we have seven probable cases that died before the confirmation of the outbreak," Bbosa said.
Uganda last reported an outbreak of Ebola Sudan strain in 2012.
In 2019, the country experienced an outbreak of Ebola Zaire. The virus was imported from neighboring Democratic Republic of the Congo which was battling a large epidemic in its north-eastern region.
In August, a new case of Ebola virus was confirmed in the city of Beni in eastern DRC. An Ebola vaccination campaign was launched last month in the city of Beni last month.
