Ebola (Bundibugyo virus) 2026: situation update and managing a suspected case

A large Ebola outbreak caused by Bundibugyo virus has been under way in the Democratic Republic of the Congo since May 2026. By 7 October 2026, 8,728 confirmed cases and 4,205 deaths had been reported ([1]). WHO declared a Public Health Emergency of International Concern on 17 May 2026 ([1]). ECDC rates the likelihood of infection for people living in the EU/EEA as very low ([1]). For clinicians, one fact stands out: unlike Zaire ebolavirus, Bundibugyo virus has no licensed vaccine and no specific treatment ([1], [3]).

As of October 2026. The situation is changing quickly; check ECDC and your national public health institute for the latest guidance.

Situation at a glance (ECDC, week 41/2026)

• DR Congo: 8,728 confirmed cases including 4,205 deaths (data to 6 October), across seven provinces. Ituri (6,513 cases) and North Kivu (1,785) are the most affected ([1]).
• Uganda: 20 confirmed cases in May–June 2026. WHO declared the outbreak there over on 27 August ([1]).
• Kenya: first imported case, announced on 6 October 2026 ([1]).
• Europe: several medically evacuated patients have been treated in high-level isolation units, including in Berlin (Germany) and Leiden (Netherlands) ([1]).
• ECDC considers it likely that the outbreak is larger than reported, because contact follow-up is incomplete ([1]).

Virus and clinical picture

• Transmission: direct contact with sick or deceased people, especially their body fluids. No airborne spread ([3]).
• Incubation period: 2–21 days, with symptoms usually after 8–9 days. Patients are considered infectious from symptom onset ([2]).
• Early symptoms are non-specific: fever, chills, severe malaise, headache, myalgia, arthralgia, sore throat, diarrhoea, vomiting, abdominal pain, conjunctival injection and a truncal maculopapular rash. Haemorrhage, jaundice, multi-organ failure and shock can follow ([2]).
• Case fatality in the 2007 and 2012 Bundibugyo outbreaks was 30–40% ([3]).
• Vaccines and therapeutics: candidate vaccines are in pre-clinical or early clinical development. WHO proposes using the Zaire vaccine rVSV-ZEBOV (Ervebo) in Bundibugyo outbreaks mainly within research protocols ([1]).

Suspected case: a structured approach (based on the RKI flowchart, 18 Sep 2026)

This section follows the German RKI flowchart ([2]). Procedures in other countries differ, so follow your national pathway.

When to suspect it: new symptoms within 21 days of a possible exposure, such as:

• direct contact with Ebola patients, deceased people or their body fluids without adequate PPE,
• direct contact with people who have Ebola-like symptoms,
• visiting or working in healthcare facilities or laboratories in the outbreak area,
• less often: contact with bats, sick primates or raw bushmeat ([2]).

First steps ([2]):

1. Isolate the patient on site in a separate room and keep a distance of 1.5 m.
2. PPE for direct contact: FFP3 respirator, goggles or face shield, disposable gown, double gloves and foot protection. Use hand disinfectant that is at least limited-virucidal.
3. Call the local public health authority. In Germany it consults the STAKOB competence centre and decides on transfer to a high-level isolation unit ([4]).
4. Diagnostics: blood, CSF if there are neurological symptoms, and urine or a nasopharyngeal swab if indicated. If the test is negative, repeat it once more than 72 hours have passed since symptom onset ([2]).

Common differential diagnoses, especially malaria, remain important in febrile returning travellers. Work them up in agreement with the public health authority.

Bottom line

The risk to the general population in Europe is very low. For anyone returning from the outbreak area, including humanitarian healthcare workers, the travel and exposure history of the last 21 days is what matters. If you suspect Ebola: isolate, protect yourself, call public health.
