Key takeaways
- The US Centers for Disease Control and Prevention reported 9,637 confirmed cases and 4,646 deaths in the Democratic Republic of the Congo as of October 20, 2026, and called it the second-largest Ebola outbreak on record.
- The Associated Press reported on October 21, 2026 that the outbreak has spread beyond Congo to four other countries and has reached central, western and eastern Africa, farther than any previous Ebola outbreak.
- The Bundibugyo strain has no approved vaccine or specific treatment, according to the World Health Organization, so control relies on surveillance, contact tracing and isolation.
- The World Health Organization advises against travel or trade restrictions on the affected countries, while urging neighbours to keep high readiness and monitor entry points.
The DRC Ebola outbreak, caused by the Bundibugyo virus, has now reached Uganda, Kenya, Nigeria and France, and has spread farther across Africa than any earlier Ebola outbreak, according to the Associated Press. The US Centers for Disease Control and Prevention (CDC) said that as of October 20, 2026, the Democratic Republic of the Congo had 9,637 confirmed cases and 4,646 confirmed deaths. The strain has no approved vaccine or specific treatment, which raises the stakes for neighbouring states.
What is the DRC Ebola outbreak and how big is it?
Ebola disease caused by Bundibugyo virus is a haemorrhagic fever for which, according to the World Health Organization (WHO), no vaccine or specific treatment exists, although candidates are being tested. The outbreak was confirmed in the DRC and Uganda in May 2026.
The CDC said the outbreak is spreading substantially faster than earlier ones and is now the second-largest on record. The European Centre for Disease Prevention and Control (ECDC) reported 9,552 confirmed cases and 4,602 deaths as of October 19, 2026, with 937 patients in isolation and 2,550 recovered. The small gap between agency totals reflects different data cut-off dates.
WHO’s most recent Disease Outbreak News update, dated October 8, 2026, put the crude case fatality ratio at 48.2% across 64 health zones in seven of the country’s 26 provinces. It described national transmission as intense but uneven, with signs of slowing in some areas and growth in others.
Why has the outbreak spread beyond Congo?
The AP reported that a recurring problem has been weak surveillance, with most early cases in other countries confirmed long after symptoms began or after travel. WHO’s own account points to a difficult setting: a humanitarian crisis, insecurity and heavy population and trade movement.
Two imported cases surfaced this week. Nigeria confirmed its first case on October 20, 2026, a woman who arrived on an international flight from Uganda and was treated at a private hospital in Abuja. Nigeria’s Health Ministry identified 44 contacts. Details of her travel history differ: Ugandan officials said she had been in the DRC, while Nigeria’s government said she had spent about two and a half weeks holidaying in Uganda, the Globe and Mail reported.

In Kenya, Health Director-General Patrick Amoth said all nine infections belong to a single cluster with no evidence of transmission outside the group, Newsweek reported, citing Reuters. Kenyan officials traced and quarantined 134 of 135 identified contacts. Uganda has recorded 20 cases, 18 recoveries and two deaths, and none of its cases is active. France, the only non-African country affected, confirmed a case in June in a doctor returning from Congo.
What is the UN doing about the DRC Ebola outbreak?
WHO, a UN specialised agency, says it is scaling up support to governments with surveillance, contact tracing, clinical care, supplies and community engagement. On the WHO regional report for the week to October 11, 2026, Dakwa health zone in Bas-Uélé province became the latest affected area, bringing the total to 65 zones. Ituri remains the main focus, though its share of cumulative cases is falling.
The Security Council has linked the health emergency to the security picture. At a meeting on September 30, 2026, ambassadors discussed clashes between Government forces and M23 rebels, tensions between the DRC and Rwanda, and the Ebola outbreak, according to UN News. The same briefing noted that the mandate of the UN stabilisation mission, MONUSCO, comes up for renewal in December.
The Center for Strategic and International Studies, a Washington think tank, argued in an analysis that insecurity dominates the operating environment far more than in earlier outbreaks. It cited recurring airport closures as a logistical barrier.
What are the risks for travel and for other countries?
WHO urged countries in the region to sustain a high level of readiness, including heightened monitoring at points of entry, while continuing to advise against restrictions on travel or trade with affected countries. The CDC said the risk to the American public and travellers remains low and that no US cases have been confirmed. It maintains Level 4 (avoid all travel) notices for Ituri and North Kivu provinces.
The ECDC said 76.9% of identified case contacts in the affected provinces were under follow-up. Contact-tracing coverage is a key measure of whether the outbreak can be brought under control.
What to watch
- Nigeria’s 44 contacts: whether any develop symptoms, which would signal local transmission beyond a single imported case.
- Kenya’s cluster: whether the nine-case total grows beyond the known family and health-worker contacts.
- Weekly DRC figures: WHO’s next situation report and Disease Outbreak News update, to see whether weekly cases (487 in the most recent WHO national tally) rise or fall.
- Contact follow-up rates: the ECDC figure of 76.9% is the benchmark to track.
- December MONUSCO renewal: how the Security Council weighs the Ebola response alongside the conflict in eastern Congo.
- Medical countermeasures: any announcement on trial results for Bundibugyo vaccines or drugs.
Frequently asked questions
Which countries have reported cases in the DRC Ebola outbreak?
Besides the Democratic Republic of the Congo, cases have been reported in Uganda, Kenya, Nigeria and France, according to AP and CNN reporting on October 21, 2026. Cases remain active in Kenya and Nigeria, while Uganda's outbreak has ended and France's patient recovered.
Is there a vaccine for the Bundibugyo strain of Ebola?
No. The World Health Organization says no approved vaccine or specific treatment exists for the Bundibugyo species of Ebola, though work is under way to test promising candidates. Response efforts therefore centre on surveillance, contact tracing, isolation and supportive clinical care.
Should travellers avoid Africa because of the Ebola outbreak?
The WHO advises against restricting travel or trade with affected countries and asks neighbours to monitor entry points. The CDC rates risk to American travellers as low overall, but advises avoiding all travel to Ituri and North Kivu provinces in the DRC.
