This is the ninth ebola outbreak in Congo since 1976, when the deadly disease was first identified.

Congo’s Health Minister on Thursday announced the first death since a new ebola outbreak was declared in the country, as well as nine other cases of people sickened by a hemorrhagic fever that is suspected as ebola.

Minister Oly Ilunga said seven people with a hemorrhagic fever, including two confirmed cases of ebola, were hospitalised in Bikoro as of Thursday. The death happened overnight at a hospital in nearby Ikoko Impenge hospital that also reported four new suspected cases of ebola.

Mr. Ilunga told The Associated Press that the patient who died was a nurse. Three other nurses also were being treated for a hemorrhagic fever, he said.

The Minister clarified that testing still must be done in nine cases, and equipment to conduct rapid testing on the patients had been dispatched.

“This situation worries us and requires a very immediate and energetic response,” he said at a news conference.

The two ebola cases were confirmed as the Zaire strain after officials in the capital, Kinshasa, were alerted early this month to the deaths of 17 people from a hemorrhagic fever and traveled to the Bikoro area to perform tests.

The deaths occurred over a period of time and ebola, which is not the only virus responsible for hemorrhagic fevers, has not been confirmed as the cause in any of the 17 cases, Mr. Ilunga said.

Bikoro Hospital director Dr. Serge Ngalebato told The Associated Press earlier Thursday that nurses at the hospital were among the five suspected ebola cases there.

“We have isolated the patients,” Dr. Ngalebato said. “There are no deaths yet, but all of the sick are presenting signs of fever, diarrhea, vomiting, abdominal pain and intense fatigue.”

Ninth ebola outbreak since 1976

This is the ninth ebola outbreak in Congo since 1976, when the deadly disease was first identified.

Ebola occasionally jumps to humans from animals, including bats and monkeys.

There is no specific treatment for ebola, which is spread through the bodily fluids of people exhibiting symptoms. Without preventive measures, the virus can spread quickly between people and is fatal in up to 90 per cent of cases.

The director of the National Institute of Biological and Bacterial Research, Dr. Jean Jacques Muyembe, said Wednesday that health experts should be able to quickly contain this outbreak because the area is so remote.

The cases could be linked to a policeman in the Bikoro health zone who presented symptoms of hemorrhagic fever and died in December, Muyembe said. His mother and 10 others then showed similar symptoms.

None of the ebola outbreaks in Congo have been connected to the massive outbreak in Guinea, Liberia and Sierra Leone in West Africa that began in 2014 and left more than 11,300 dead.
