Congo Ebola Deaths Pass 4,018 Without a Licensed Vaccine

Congo’s health ministry has recorded 4,018 Ebola deaths among 8,300 confirmed cases, the fastest-growing outbreak of the disease on record. The figures, released by the ministry and repeated in a 1 October presidential task-force report, put the death rate at 48.4%. More than 2,000 patients have recovered.

The virus is Bundibugyo, a species that still has no licensed vaccine and no approved drug, even as shots and antibodies for a different Ebola species sit in stockpiles built after 2018.

Why This Ebola Outbreak Has No Vaccine

Ervebo, the only licensed Ebola shot, carries a Zaire glycoprotein. Inmazeb and Ebanga, the licensed antibody drugs, were built for the same species. Bundibugyo is a different virus, and WHO says outbreak control still rests on finding cases, isolating the sick, tracing contacts and burying the dead safely, because there are no approved vaccines or specific treatments for Bundibugyo virus disease.

That gap is not a surprise that arrived in May. Bundibugyo was identified in 2007 in western Uganda and caused a second cluster in Congo in 2012. Together those events produced fewer than 200 cases. Drugmakers had little commercial reason to run the huge trials a new species requires, so the products licensed after West Africa and after North Kivu were never labelled for this virus.

The 17th Ebola outbreak in the Democratic Republic of the Congo was declared on 15 May 2026 in Ituri province. WHO determined a public health emergency of international concern two days later. Four and a half months on, the caseload has already passed the 3,470 cases and 2,287 deaths recorded in the 2018-2020 North Kivu and Ituri epidemic, which was caused by Zaire virus and fought with ring vaccination and monoclonal antibodies.

Congo Passed 1,000 Cases in 40 Days

CDC says the 2026 outbreak reached 1,000 confirmed cases within 40 days of response activation. The 2018 epidemic in the same eastern provinces took about 235 days to cross that line. A CDC field comparison of five epidemics found 5,458 confirmed cases in the first 100 days after detection on 14 May, with 2,606 deaths, and said no earlier Ebola outbreak had produced more than 800 cases in that window.

Those 5,458 cases were seven times the 759 counted in the first 100 days of the 2014 West Africa epidemic, still the largest on record at 28,610 cases and 11,308 deaths, and 16 times the 333 confirmed and probable cases logged in the first 103 days of the 2018 Congo outbreak. CDC now ranks the Bundibugyo epidemic as the second-largest Ebola outbreak worldwide.

FIVE EBOLA OUTBREAKS COMPARED

The West Africa first-100-day count includes suspected, probable and confirmed cases, and the 2018 Congo figure spans 103 days, so the multiples are a speed test rather than a perfect like-for-like ledger. The direction is not in dispute. This epidemic was already larger at detection than the others in the comparison, with 246 suspected cases and eight laboratory-confirmed infections on the day it was declared, a sign that several chains were moving before anyone named the virus.

Bundibugyo Was a Footnote for 19 Years

Until this year the species had a reputation as the milder cousin. CDC records 42 deaths among 131 cases in Bundibugyo district in 2007, a 32% death rate, and 34 deaths among 62 cases around Isiro in 2012, a 55% rate. Both outbreaks stayed inside one district or one health zone and ended within six months. WHO cites historical death rates of about 30% and 50% for those two events. The 2026 crude rate of 48.4% sits in that band, which is still below the 66% recorded in 2018-2020, and still high enough to empty households.

Incubation runs from two to 21 days. People are not infectious until symptoms start, and the first days look like malaria: fever, fatigue, muscle pain, headache, sore throat, then gut illness and, in some patients, bleeding. Without a PCR test, clinics in Ituri and North Kivu cannot tell the two apart. Fruit bats are the suspected reservoir, as with other ebolaviruses, but that does not help a nurse in Bunia tonight.

HOW A RARE VIRUS BECAME A NATIONAL EPIDEMIC

1. 15 May 2026: Congo’s health ministry declares the 17th Ebola outbreak, in Ituri.
2. 17 May 2026: WHO determines a public health emergency of international concern for Bundibugyo virus disease in Congo and Uganda.
3. 21 June 2026: Uganda confirms its last related case, after 21 confirmed and probable infections and three deaths, with limited spread mainly among health workers.
4. 21 August 2026: The first 100 days close at 5,458 confirmed cases and 2,606 deaths across 57 of Congo’s 519 health zones.
5. 23 September 2026: WHO counts 7,890 confirmed cases in 63 health zones across seven of 26 provinces, with Ituri still the centre at 6,032 cases.
6. 1 October 2026: The presidential task force reports 8,300 confirmed cases and 4,018 deaths, and 76 new infections on 30 September.

One travel-related case was treated in France. CDC said on 10 September that it had found no community spread outside Congo. Uganda’s last confirmed case remains 21 June. South Kivu has reported no confirmed case since 29 May.

Unpaid Trackers, Then a Killing in Butembo

The people who produce the 8,300 figure are some of the same people who have not been paid. In Bunia, the Ituri capital and the heart of the outbreak, surveillance staff who find contacts of infected patients gathered to demand wages, then were dispersed. Their placards read “No money, no data!” and “No payment for months.” Front-line crews have walked off the job several times since May, which cuts the very lists the response depends on.

Surveillance Crews Walked Off the Job

Micheline Kayimpa, a mother of four working in an Ebola isolation ward in eastern Congo, told interviewers she had not received a government paycheck since she started in June, and that her name was misspelled on payroll files. She stopped work for three days, then went back.

I’ve been working here since June, but I haven’t received a single penny in wages.

Africa CDC has said newly confirmed cases are falling in some hotspots, and has also said that dip could be insecurity and communities that will not cooperate, not a true retreat of the virus. A task-force line for 30 September cuts against any victory lap: 76 new confirmed cases that day, up from 53 the day before, a 43% rise, with no new health zone added. Ituri logged 43 of those infections and North Kivu 31, or 97% of the day’s total. The fire is still in the same two provinces.

A Radio Appeal, Then a House Fire

On 27 September in Butembo, a North Kivu hotspot, a group attacked Marie-Célestin Karondwa at his home after he had gone on local radio to defend government measures and to urge distance and handwashing. Karondwa was a local official of the ruling Union for Democracy and Social Progress. His house was looted and set on fire. He died of his injuries in hospital. Mourners buried him in Butembo on 1 October.

His granddaughter, Sagesse Kavira, said the attackers beat him and then set the house on fire. The party called him an innocent victim for having defended its position “on the existence of the Ebola virus disease” and the threat it poses. That phrasing is the point of friction. Some residents still treat Ebola as a hoax, a hangover from how earlier outbreaks were handled and from years of graft, and a village-centred push launched in September is running into that wall.

More than 50 health workers have died after catching the virus. Médecins Sans Frontières said one of its staff members tested positive for Bundibugyo while working on the response and was flown to the Netherlands under a medical protocol. Leiden University Medical Center said the patient arrived late on 1 October and was moved into a high-level isolation unit. The Dutch health ministry described the patient as an MSF doctor. Identity and nationality were withheld.

The human cost of this crisis is unprecedented in the DRC, with communities facing the largest Ebola disease outbreak ever recorded in the country.

MSF said training and protective gear cannot drive the risk of exposure to zero. For Congolese staff who cannot board a private aircraft to Leiden, that sentence is the job description.

WHERE THE RESPONSE IS BREAKING

• Pay: Surveillance teams in Bunia have struck over wages unpaid for months, and at least one isolation nurse in the east had not been paid since June.
• Contacts: Follow-up sat at 80.6% in the 1 October task-force report, against a 95% target.
• Beds: Only half of suspected cases were being moved to treatment centres.
• Shots: A temporary Ervebo stockout halted vaccination in Ituri, the epicentre.
• Trust: A ruling-party official was beaten to death in Butembo after defending the response on the radio.

Each of those failures feeds the next. Unpaid trackers miss contacts, missed contacts never reach a bed, and a community that has watched a politician’s house burn is slower to report a fever.

Ervebo Goes Into a Trial, Then Runs Short

WHO’s Strategic Advisory Group of Experts on Immunization reviewed animal and antibody data and found hints of cross-protection, then said the evidence is still too thin to know whether Ervebo gives people meaningful protection against Bundibugyo. Updated emergency guidance on 31 August said the shot should be used only within research protocols, with a ring randomized trial to generate efficacy data and with clear public talk about what is unknown.

Doses still moved. WHO allocated Ervebo for a Phase 3 ring trial in Ituri and for front-line staff, and health workers in Bunia received the first shots in mid-September. Maj. Gen. Gaby Kasongo Mulumba, the military governor of Ituri, said those workers were vaccinated first because they are the most exposed. The design copies the Guinea ring study that showed Ervebo works against Zaire: contacts of a case are enrolled, some get the shot, others do not, and infection rates are compared.

That is not the 2018 playbook. In North Kivu, Ervebo was a public-health tool used at scale around every confirmed case. Here it is an experiment, and the experiment has already hit logistics. The 1 October task-force report said a temporary break in Ervebo supply suspended vaccination in Ituri. WHO experts have also named experimental antibodies and antivirals, including MBP134, maftivimab and remdesivir, plus the oral drug obeldesivir for people who have been exposed, as candidates for trials. That is not a licensed treatment for this virus today.

North Kivu’s Death Rate Runs Ahead of the Country

WHO’s 23 September snapshot, the last full geographic breakdown published in its Disease Outbreak News, counted 7,890 confirmed cases and 3,799 deaths in 63 health zones. Forty-eight zones in six provinces had reported at least one case in the previous 21 days. Ituri, with cases in 28 of 36 health zones, remained the centre. North Kivu was second, with 1,480 confirmed cases, including 567 in those 21 days, and the highest provincial death rate at 59.7%. WHO said it was still trying to learn why so many North Kivu patients die.

THE 23 SEPTEMBER MAP

• Ituri: 6,032 confirmed cases, still the epicentre, with a slow decline from a mid-August peak.
• North Kivu: 1,480 cases and a 59.7% death rate, with incidence up through mid-September.
• Spread: Tshopo, Haut-Uélé, Bas-Uélé, South Kivu and Sud Ubangi make seven provinces in all, after a case in Bulu, Sud Ubangi, on 10 September and cases in Dungu, Haut-Uélé, on the South Sudan border.
• South Kivu: No new confirmed case since 29 May.

Community deaths remain high, which WHO reads as late detection and weak access to care. Patients who die at home infect the people who wash and bury them. The 8,300 and 4,018 totals from 1 October sit on top of that map; they do not redraw it. Sud Ubangi’s single-zone foothold still matters because it sits on the north-west border with the Central African Republic, a different frontier from the eastern cluster.

Contact Lists Cover Only a Fraction of Exposures

Jean Kaseya, director-general of Africa CDC, said a caseload then above 7,000 should have produced about 420,000 contacts. WHO, as of 23 September, recorded 32,342 contacts requiring follow-up. That is not a rounding error. It is the difference between a ring you can close and a community outbreak you chase. Kaseya said that when the outbreak is at community level, control is not a word that applies.

The 1 October task force put contact follow-up at 80.6%, short of the 95% target, and said only half of suspected cases were reaching treatment centres. WHO risk language, last updated in August, still rates the danger as very high inside Congo, high for countries that share a land border, and low for the rest of Africa and the world. It advises against travel and trade bans.

A one-day jump to 76 confirmed cases with no new health zone is the pattern of a virus that has room to move inside places it already holds. Unpaid trackers, a burned house in Butembo, and a licensed vaccine used as a trial and then paused in Ituri are now part of that pattern, not side stories around it.
