Ebola Outbreak in Congo Spreads to Seventh Province as Cases Keep Climbing

As of Wednesday, 6,942 Ebola cases and 3,349 deaths have been reported in Congo, with displacement sites among the most precarious settings.

Sud-Ubangi became the seventh province affected, far from the eastern provinces where the outbreak had been concentrated.

Why does a single lab result in Sud-Ubangi matter so much?

Mimi

Because it's the first affected province in the west. Every earlier case was in the east, and Sud-Ubangi doesn't border any of those six provinces.

Worth noting how little we actually know. It's one sample from the Bulu health district, and the governor's statement gave no other details about the source of the infection.

Mark

What about the Kinshasa case in May?

Mimi

That was a person who had traveled from eastern Congo. The capital wasn't classified as an affected province, so Sud-Ubangi is counted as the first in the west.

Mark

And the overall numbers?

Mimi

6,942 cases and 3,349 deaths as of Wednesday, per government figures. WHO says it's out of control and on track to pass the West Africa outbreak, which killed more than 11,000.

Luke

That's a projection, not a result. "On track to surpass" is WHO's assessment, and the source doesn't say when that might happen.

Mark

Is any part of the picture improving?

Mimi

Ituri, the epicenter, has seen declines recently. But North Kivu and Haut-Uele have risen sharply, and the strike, insecurity and displacement all make the response harder.

And the vaccine picture is mixed. Ervebo was effective against Zaire, not Bundibugyo. Trials for a Bundibugyo vaccine are underway, so nothing is licensed yet.

  • A single laboratory sample has pushed Ebola into western Congo for the first time, unsettling a region that believed itself beyond the outbreak's reach.
  • The WHO calls the epidemic out of control and the fastest-growing Ebola outbreak on record, with cases and deaths still climbing in North Kivu and Haut-Uele.
  • Insecurity, displacement camps, a health workers' strike, and constant movement of people are making every containment effort harder to hold.
  • Vaccination of front-line workers has begun with Ervebo, and trials for a Bundibugyo-specific vaccine are underway, with Ituri set to start next week.
  • All eyes are now on Sud-Ubangi for further cases and on the Central African Republic border, where a crossing would widen the crisis.

Far to the northwest of the wounded east, a sample taken from the Bulu health district has carried the Bundibugyo strain of Ebola into Sud-Ubangi, a province that until now had stood outside the reach of this outbreak. It is a quiet turn in a sickness that has already consumed thousands, and it reminds us how a disease moves not by map but by the paths people take when they flee, trade, travel, or simply cannot find care. Congo now counts 6,942 cases and 3,349 deaths, and the question that hangs over the coming weeks is whether this single finding is an isolated thread or the first sign of a wider weaving across the border.

A statement from the governor of Sud-Ubangi, in northwestern Congo, brought news that health officials had long feared. Laboratory tests at the national research institute had found the Bundibugyo strain of Ebola in a sample from the Bulu health district. The source of the infection has not been identified, but the finding makes Sud-Ubangi the seventh province affected and the first in the west, a region that had watched the outbreak from a distance.

The epidemic has been growing for months. As of Wednesday, Congo had reported 6,942 cases and 3,349 deaths. The World Health Organization describes it as out of control and on track to surpass the 2014 to 2016 West Africa epidemic, the deadliest on record. Even as cases fall in Ituri, the epicenter, they are rising sharply in North Kivu and Haut-Uele. Insecurity, displacement, a strike by health workers, and constant movement of people all feed the spread, and displacement sites remain among the most vulnerable places of all.

The fight now runs on several fronts. Front-line workers have begun receiving Ervebo, a vaccine proven in earlier outbreaks of the more common Zaire strain, while trials search for a vaccine that works against Bundibugyo itself. Vaccinations in Ituri are due to begin next week. The WHO has warned the virus could reach the Central African Republic and South Sudan. For now, the people of Sud-Ubangi are waiting to learn whether that single sample was the only one, or the first of many.

A statement issued Thursday by the governor of Sud-Ubangi province, in northwestern Congo, carried news that health officials had been dreading. Governor Jean-Rene Galekwa Vundawe said laboratory tests by Congo's national research institute had found the Bundibugyo virus in a sample. Bundibugyo is the rare strain of Ebola behind the current outbreak. Local media reported the statement on Friday.

The sample came from the Bulu health district. The statement gave no other details about the source of the infection. Even so, the finding makes Sud-Ubangi the seventh province affected, and the first in western Congo. Until now the outbreak had been concentrated in the east.

The six provinces with previously confirmed cases are Ituri, North Kivu, South Kivu, Haut-Uele, Tshopo and Bas-Uele. Sud-Ubangi borders none of them. It does border the Central African Republic. A case was detected in Kinshasa in May, in a person who had traveled from eastern Congo, but the capital was never classified as an affected province.

The scale is already large. According to the latest government figures, as of Wednesday Congo had reported 6,942 cases and 3,349 deaths. The World Health Organization has described the outbreak as out of control and the fastest-growing Ebola outbreak on record. It says the outbreak is on track to surpass the 2014-2016 West Africa epidemic, the deadliest ever, which killed more than 11,000 people, mostly in Guinea, Liberia and Sierra Leone.

The pattern inside the country is shifting. In recent weeks, new cases and deaths have declined in Ituri, the epicenter, but they have risen sharply in neighboring North Kivu and in Haut-Uele. Conditions make the response harder: insecurity, displacement, a health workers' strike and intense movement of people are all feeding the spread. Displacement sites are of particular concern, since residents there already live in extremely precarious conditions.

The regional risk is also on the table. Last month WHO warned the virus could cross from Congo into the Central African Republic and South Sudan, both of which border affected provinces. Uganda, which reported 20 cases since May, declared itself free of Ebola in July.

On the medical front, Congo began vaccinating health and other front-line workers last month with Ervebo, a vaccine that worked in earlier outbreaks caused by the more common Zaire type of Ebola. Clinical trials are underway to find a licensed vaccine for Bundibugyo specifically. Placide Mbala Kingebeni, Africa CDC's director for research, clinical trials and innovation, said Thursday that the vaccination trials began in Tshopo, Haut-Uele and Bas-Uele. Vaccinations in Ituri are set to start next week.

What to watch now is whether more cases surface in Sud-Ubangi beyond the single sample, and whether the virus moves across the border into the Central African Republic.
