KINSHASA, Democratic Republic of the Congo — The Democratic Republic of the Congo is confronting its most severe Ebola outbreak on record, with the death toll surpassing 2,500 as United Nations officials warn that the virus is spreading “exponentially” across an increasingly vast part of the country.
UN Ebola coordinator Julien Harneis said the epidemic is now advancing across an area larger than France, while emergency teams are struggling to keep pace with new infections, insecurity, shortages of funding and attacks on healthcare personnel.
The outbreak, officially declared in May 2026, is caused by the Bundibugyo species of Ebola virus, a strain for which there is currently no licensed vaccine or specifically approved treatment, although vaccine and treatment trials are underway.
Congo Records Its Largest Ebola Outbreak Ever
The scale of the crisis has escalated sharply in only a matter of weeks.
WHO reported that as of August 12, Congo had recorded 4,665 confirmed cases and 2,184 deaths, with cases detected in 54 health zones across six provinces — Ituri, North Kivu, South Kivu, Haut-Uélé, Tshopo and Bas-Uélé.
By August 19, official government figures cited by Reuters showed the number of confirmed cases had climbed beyond 5,000, with at least 2,378 deaths.
The latest UN assessment reported by Reuters on August 21 pushed the death toll beyond 2,500, underscoring how quickly the situation continues to deteriorate.
The current epidemic has already surpassed Congo’s previous largest outbreak, which occurred from 2018 to 2020 and recorded more than 3,300 cases.
Why Health Officials Are So Alarmed
The speed of transmission is one of the biggest concerns.
WHO said the outbreak is expanding faster than any previous Ebola outbreak recorded in Congo, with sustained transmission occurring across interconnected geographic clusters. During the week of August 3 to 9 alone, authorities recorded 579 new confirmed cases and 304 deaths, the highest weekly totals at that point in the outbreak.
AP reported that by August 21, figures had risen to approximately 5,290 confirmed cases and 2,516 deaths, while Africa CDC estimates suggested that only a fraction of infections may be detected in some affected communities.
Weak contact tracing presents another major challenge. In some areas affected by conflict and displacement, health authorities are struggling to identify everyone who may have been exposed, allowing hidden transmission chains to continue.
Healthcare Workers Are Becoming Victims
The outbreak is also taking a mounting toll on the people trying to stop it.
Harneis said roughly 160 healthcare workers had contracted Ebola and 43 had died.
At the same time, response teams face threats unrelated to the disease itself.
More than 260 attacks against healthcare workers have reportedly occurred over the previous six months, according to the UN coordinator, while ambulances and medical facilities have been attacked or damaged. Eight healthcare workers were reported killed in violence.
Misinformation and distrust have worsened the situation.
Some communities have reportedly encountered conspiracy theories claiming that Ebola is fabricated, while restrictions on traditional burial practices have also caused anger and resistance toward response teams.
WHO has repeatedly stressed that community cooperation is essential because fear and distrust can delay testing, contact tracing and treatment — allowing infected people to remain in their communities longer.
A Humanitarian Crisis Inside Another Crisis
The epidemic is unfolding in eastern Congo, a region already destabilized by decades of armed conflict, displacement and fragile public infrastructure.
WHO says insecurity, population movement and limited access to healthcare are making it significantly harder to identify cases, isolate infected patients and trace contacts.
The UN has also warned that funding is becoming dangerously tight.
Harneis said available emergency funds could be exhausted within weeks unless additional international support arrives. Aid reductions in recent years have already weakened the ability of humanitarian organizations to respond at the required scale.
Even paying frontline responders has become complicated. Restrictions affecting commercial flights have disrupted cash deliveries and banking operations in some affected areas, according to Reuters.
Vaccine Effort Offers Some Hope — But There Is a Catch
There is currently no licensed vaccine specifically approved against the Bundibugyo strain.
However, WHO and global health partners announced plans to provide 70,000 doses of the Ervebo Ebola vaccine to Congo.
Ervebo is approved for a different Ebola species, but laboratory and animal evidence suggests it could potentially offer some protection against Bundibugyo virus. Around 20,000 doses are expected to be used in clinical trials, while tens of thousands more are being allocated to frontline personnel.
WHO has also said clinical trials are underway to identify the first effective treatments specifically targeting Bundibugyo virus disease.
Could Ebola Spread Beyond Congo?
Imported cases have already demonstrated the outbreak’s ability to cross borders.
Cases linked to the Congo outbreak have been detected in Uganda, France and Germany, although WHO says there has been no sustained transmission outside the Democratic Republic of the Congo.
WHO currently assesses the overall risk as very high inside Congo, high for neighboring countries, particularly those sharing land borders with Congo, but low at the wider regional and global level.
That distinction is important: the outbreak is extremely serious, but available evidence does not currently indicate uncontrolled global transmission.
What Happens Next Could Determine How Large This Outbreak Becomes
The numbers alone make the 2026 epidemic historic for Congo.
But health officials say the decisive issue will be whether the response can begin expanding faster than the virus itself.
That means rapidly improving surveillance, identifying contacts, strengthening treatment facilities, protecting healthcare workers, rebuilding trust within communities and securing enough international funding to sustain operations.
Until those gaps are closed, the most troubling warning may not be that Ebola has already killed more than 2,500 people.
It is that the epidemic is still expanding.
