In the northwest of the Democratic Republic of Congo, a laboratory result from the Sud-Ubangi province has added a new and troubling chapter to a sickness that has already scarred the country's east. The Bundibugyo strain of Ebola, rarer than the variety that drove earlier epidemics, has now crossed into a region far from where it first gathered, bordering the Central African Republic. Against a backdrop of insecurity, displacement, and a health workers' strike, the outbreak has reached more than seven thousand recorded cases and over three thousand deaths, a reminder of how quickly a disease
Ebola Spreads to Congo's Seventh Province as Bundibugyo Outbreak Reaches Western Congo
At least 3,349 people have died and 6,942 cases have been reported, with the outbreak worsened by displacement, insecurity, and a health workers' strike.
The outbreak has jumped well beyond the east
Mark
Why does Sud-Ubangi matter more than just being number seven?
Mimi
Because of where it sits. It doesn't border any of the six eastern provinces already affected, and it's the first in western Congo. That suggests the virus moved across long distances, not just to a neighbor.
Luke
Careful, though. The source says it's not adjacent. It doesn't say how the virus got there. The governor's statement gave no information on the source of infection.
Mark
So we know a sample tested positive, and little else.
Luke
Right. One sample from the Bulu health district, confirmed by the national research institute. How many cases there are, we don't know from this reporting.
Mimi
There's the Kinshasa case in May too, a traveler from the east. The capital wasn't counted as an affected province, so travel clearly carried the virus west before.
Mark
What about the numbers, 6,942 cases and 3,349 deaths?
Luke
Those are government figures as of Wednesday. And the claim that it will surpass West Africa is WHO's projection, not a fact yet.
Mimi
The conditions matter: insecurity, displacement, a health workers' strike. Displacement sites worry officials most.
Mark
And the vaccine?
Luke
Ervebo targets the Zaire type. Nothing here says it protects against Bundibugyo; trials for a licensed vaccine are still going.
Le Pouls
- Bundibugyo Ebola has reached Sud-Ubangi, Congo's seventh affected province and the first in the west, bordering the Central African Republic.
- The outbreak is already the fastest-growing on record, with 6,942 cases and 3,349 deaths reported, and WHO says it is out of control.
- Cases are falling in Ituri but surging in North Kivu and Haut-Uele, while displacement sites and a health workers' strike strain every response.
- Vaccine trials for Bundibugyo have begun in Tshopo, Haut-Uele and Bas-Uele, with Ituri next, while the older Ervebo vaccine is being used for front-line staff.
- Health officials are watching for spread into the Central African Republic and South Sudan, and whether the Sud-Ubangi case becomes a chain of transmission.
In the northwest of the Democratic Republic of Congo, a laboratory result from the Sud-Ubangi province has added a new and troubling chapter to a sickness that has already scarred the country's east. The Bundibugyo strain of Ebola, rarer than the variety that drove earlier epidemics, has now crossed into a region far from where it first gathered, bordering the Central African Republic. Against a backdrop of insecurity, displacement, and a health workers' strike, the outbreak has reached more than seven thousand recorded cases and over three thousand deaths, a reminder of how quickly a disease moves where people move. What remains unknown is whether this single detection marks the beginning of a wider western chain or a limited episode that can still be contained.
On Thursday, the governor of Sud-Ubangi province in northwestern Congo, Jean-Rene Galekwa Vundawe, announced that laboratory tests from his province had found the Bundibugyo virus. The sample came from the Bulu health district, and the finding was run by Congo's national research institute. It makes Sud-Ubangi the seventh Congolese province touched by an outbreak that is already the fastest-growing of its kind on record.
What makes the news weighty is geography. Sud-Ubangi borders the Central African Republic and none of the six eastern provinces where the outbreak had been concentrated. It is the first affected province in the west, a sign that the disease has moved well beyond its original zone. Official figures as of Wednesday count 6,942 cases and 3,349 deaths, and the World Health Organization says the outbreak is out of control and on track to surpass the 2014-2016 West Africa epidemic.
The picture inside the affected zone is uneven. Cases have eased in Ituri, the epicenter, but climbed sharply in North Kivu and Haut-Uele. Insecurity, displacement, a health workers' strike, and heavy movement of people make the response harder, and displacement sites, where residents already live in precarious conditions, are of particular concern. WHO has warned the virus could reach the Central African Republic and South Sudan.
On the medical front, front-line workers began receiving the Ervebo vaccine last month, though it was proven against the more common Zaire strain rather than Bundibugyo. Trials for a Bundibugyo vaccine have started in several provinces, with vaccinations in Ituri expected next week. The coming weeks will show whether the Sud-Ubangi case stays isolated or becomes a chain of transmission in the west.
On Thursday, the governor of Sud-Ubangi province in northwestern Congo, Jean-Rene Galekwa Vundawe, issued a statement saying that laboratory tests had found the Bundibugyo virus in a sample from his province. Local media reported it on Friday. The finding makes Sud-Ubangi the seventh Congolese province touched by an outbreak that is already the fastest-growing of its kind on record.
The tests were run by Congo's national research institute. The sample came from the Bulu health district, according to the governor's statement, which gave no further details about the source of the infection. Bundibugyo is a rare form of Ebola, and it is the one driving the current outbreak.
The location is what makes the news significant. Sud-Ubangi borders the Central African Republic, and it does not border any of the six eastern provinces where confirmed cases had already been found: Ituri, North Kivu, South Kivu, Haut-Uele, Tshopo and Bas-Uele. It is the first affected province in western Congo, so the outbreak has now jumped well beyond the east where it had been concentrated. In May, a case was detected in Kinshasa in a person who had traveled from eastern Congo, but the capital was not classified as an affected province.
The latest government figures, as of Wednesday, count 6,942 cases and 3,349 deaths. The World Health Organization has said the outbreak remains out of control and is on track to surpass the 2014-2016 West Africa epidemic, the deadliest Ebola outbreak on record, which killed more than 11,000 people, mainly in Guinea, Liberia and Sierra Leone.
The pattern inside the affected zone is shifting. In recent weeks, new cases and deaths have declined in Ituri, the epicenter, but have risen sharply in neighboring North Kivu and Haut-Uele. The spread is happening under hard conditions: insecurity, displacement, a strike by health workers, and intense movement of people. Displacement sites are of particular concern, since residents there already live in extremely precarious circumstances.
The wider region is watching. Last month WHO warned that the outbreak could spread from Congo into the Central African Republic and South Sudan, both of which border affected provinces. Uganda, by contrast, reported 20 cases since May and declared itself free of Ebola in July.
On the medical front, Congo began vaccinating health workers and other front-line staff last month with Ervebo. That vaccine worked in past outbreaks caused by the more common Zaire type of Ebola, not Bundibugyo. Clinical trials are under way to find a licensed vaccine for Bundibugyo itself. Placide Mbala Kingebeni, Africa CDC's director for research, clinical trials and innovation, said Thursday that the vaccination trials started in Tshopo, Haut-Uele and Bas-Uele provinces. Vaccinations in Ituri are set to begin next week.
What to watch now is whether the Bulu finding stays an isolated detection or becomes a chain of transmission in the west, and whether cases cross the border into the Central African Republic or South Sudan.
