Congo Ebola outbreak passes 7,200 cases as North Kivu surge delays hopes that epidemic has peaked

The Democratic Republic of the Congo’s Ebola epidemic remains severe and geographically uneven despite early signs that transmission is declining in some of the worst-affected areas, United Nations officials said on September 15. Reuters reported more than 7,200 confirmed cases and 3,510 deaths across seven provinces in the latest operational figures, making the outbreak the second-deadliest Ebola epidemic recorded globally after the 2014-2016 West Africa crisis. Daily case counts have fallen from around 120 at their mid-August peak to roughly 80, but health officials said the decline is not yet broad or sustained enough to conclude that the epidemic has passed its overall peak.

World Health Organization data from September 10 showed how rapidly the epidemic had expanded even before the newest figures. At that point, the Democratic Republic of the Congo had recorded 7,022 confirmed cases and 3,398 confirmed deaths, while WHO reported a case-fatality ratio of approximately 48%. Earlier in the outbreak, confirmed cases were concentrated primarily in Ituri, but the virus has progressively expanded across health zones in North Kivu, Haut-Uélé, Tshopo and other provinces.

How large is the 2026 Ebola outbreak in the Democratic Republic of the Congo?

The outbreak has grown from hundreds of cases in May and June to several thousand by September, making it the largest Ebola epidemic ever recorded inside the Democratic Republic of the Congo. WHO reported 6,757 confirmed Congolese cases by September 7, up by 963 cases in less than two weeks, with 61 health zones across six provinces affected at that stage. Updated UN figures cited by Reuters on September 15 placed the epidemic above 7,200 confirmed cases and suggested its geographic footprint had expanded further.

The exceptionally high death toll is another defining feature. WHO’s September data showed mortality close to half of confirmed cases, although fatality rates can vary according to how quickly patients are identified and receive supportive treatment. Delayed detection remains particularly dangerous because patients arriving late at treatment centres are harder to save and have more time to expose family members, caregivers and health workers before isolation.

Is the Ebola outbreak finally beginning to slow down?

There are meaningful signs of progress, but they are not uniform. Reuters reported that around ten of the 62 affected health zones had gone more than 22 days without a newly detected case, while transmission in parts of Ituri appeared to be moving under greater control. Daily case counts have also declined substantially from their August high, suggesting that vaccination, isolation, contact tracing and community engagement are reducing spread in some locations.

The problem is that North Kivu is moving in the opposite direction. UN officials described conditions there as alarming, with 555 new cases recorded during the previous 21 days according to Reuters. A national epidemic can therefore appear to improve numerically while still expanding aggressively in specific provinces, making declarations that Ebola has peaked premature until new hotspots also begin declining.

Why is North Kivu becoming the most concerning Ebola hotspot?

North Kivu combines several conditions that make infectious-disease control unusually difficult. Communities experience high population mobility, displacement associated with armed conflict and insecurity that can obstruct access for health teams. Some residents also move through informal border routes or between mining and trading communities, reducing the effectiveness of surveillance concentrated at official crossings.

Health workers cannot conduct routine contact tracing efficiently when roads are insecure or communities are repeatedly displaced. WHO has also documented attacks on healthcare during the outbreak, further weakening trust and discouraging patients from seeking early treatment. The epidemiological problem is therefore inseparable from the security environment, because controlling Ebola requires responders to find cases quickly and repeatedly return to communities for monitoring and vaccination.

How does the Bundibugyo strain differ from Ebola outbreaks involving the Zaire virus?

The 2026 epidemic is caused by Bundibugyo ebolavirus rather than the Zaire ebolavirus responsible for several previous high-profile outbreaks. Both can cause severe haemorrhagic fever and spread through direct contact with infected bodily fluids, but available vaccines and therapeutic evidence differ between virus species. WHO and partner agencies consequently have to adapt vaccination and treatment strategies to the specific virus involved rather than assuming every Ebola outbreak can be managed identically.

The outbreak was declared a Public Health Emergency of International Concern in May, reflecting both its rapid expansion and the possibility of international spread. Cases linked to the Democratic Republic of the Congo were previously identified in Uganda, France and Germany, although Uganda and France subsequently completed enhanced monitoring periods without sustained transmission. The continuing epidemic inside Congo means neighbouring countries still require surveillance even where imported cases have been contained.

Why is Ebola killing such a high proportion of confirmed patients in this outbreak?

WHO has linked the high case-fatality ratio to delays in detection and difficulties obtaining timely, adequate clinical care. Ebola patients benefit from early fluid replacement, management of complications and treatment in specialised facilities, but delayed presentation can substantially reduce the chances of survival. A health system operating amid conflict and displacement cannot always provide those services rapidly enough.

Children have been especially affected. UNICEF reported in August that more than 300 children had already died and that mortality among confirmed children under five exceeded 60%, substantially above the rate among adults in its available data. Ebola has also disrupted routine healthcare, with families avoiding facilities and medical resources being redirected toward the epidemic, creating indirect health consequences beyond the virus itself.

Could the epidemic spread much further across Central Africa?

The risk remains real but is not inevitable. WHO says formal border screening, surveillance and preparedness continue at airports, ports and land crossings, while previous imported cases outside the Democratic Republic of the Congo have not produced sustained international outbreaks. Informal travel routes and high population mobility nevertheless create vulnerabilities that cannot be eliminated through official border controls alone.

Regional spread would become more likely if transmission accelerates in health zones close to international borders or if surveillance capacity weakens because of funding shortages or insecurity. The most effective strategy remains reducing transmission at the source rather than relying on border screening after infected people begin travelling. That is why improvement in Ituri offers encouraging evidence but the deterioration in North Kivu remains such an important warning.

What are the most important signs to watch as Congo tries to turn the Ebola outbreak around?

The daily case trajectory needs to decline across several provinces simultaneously rather than only in the original epicentre. Health officials will also watch how many affected health zones go through full transmission periods without new cases, whether death rates begin falling and whether responders can reach North Kivu communities consistently. A sustained reduction in those indicators would provide much stronger evidence that the epidemic has peaked nationally.

For now, the situation contains genuine progress alongside substantial danger. Calling the outbreak uncontrolled everywhere would ignore improvements in parts of Ituri, while declaring victory would ignore thousands of deaths and active expansion elsewhere. The September picture is therefore best understood as an epidemic beginning to yield to public-health intervention in some areas while continuing to threaten large populations in others.
