Kenya has discharged its last patient being treated for Ebola and released the final 11 monitored contacts from quarantine, marking a milestone in its response to an outbreak that began with an imported case in October.
The patient and the contacts went home on 11 November 2026. The first day of a 42-day countdown is 12 November. As of 11 November, Kenya had not been declared free of the disease: that declaration would depend on the period passing without another confirmed case.
The period is expected to end on or around 23 December if no new case is recorded. The 42 days are twice the maximum incubation period for the disease, meaning twice the longest usual interval between infection and the appearance of symptoms.
From a traced cluster to the last discharge
Kenya confirmed its first case of Bundibugyo virus disease, a form of Ebola disease, on 6 October. The person had returned from the Democratic Republic of the Congo through Uganda. Eight further cases were identified among four family members and four health workers who had cared for the first patient before Ebola was suspected.
All eight were already in quarantine as known contacts when they developed symptoms. As of 3 November, there was no evidence of transmission outside that cluster. The absence of evidence at that point was not a guarantee that a new case could not be found.
Nine cases had been confirmed in Kenya by 11 November. Two people had died and seven had recovered. Five patients were discharged on 3 November, a sixth went home on 6 November and the last patient was discharged on 11 November. The last new case had been confirmed on 19 October.
Health teams identified 135 contacts in connection with the initial case. That total includes eight people who later became confirmed cases and nine who had left Kenya, with the relevant authorities notified. Of the remaining 118, 52 were still being monitored as of 3 November. The final 11 completed their monitoring in good health on 11 November.
What the countdown means
Contact monitoring and the national countdown serve different purposes. Contacts are followed for up to 21 days to see whether they develop symptoms after a possible exposure. A person being monitored is not necessarily infected. The subsequent 42-day period is intended to provide additional time for any otherwise undetected chain of transmission to become apparent before the outbreak is declared over.
The date of 23 December is therefore a conditional target, not a declaration already made. Rapid response teams are expected to remain on alert across the country and alerts will be investigated. Follow-up care and support for survivors are also planned.
In early November, response measures included testing at five designated laboratories, two of them mobile facilities at the Ugandan border, and coordination with neighbouring countries on surveillance.
Understanding Bundibugyo virus disease
Bundibugyo virus disease can spread through direct contact with the blood or other body fluids of a person who is sick or has died, or with contaminated materials. Symptoms can include fever, tiredness and muscle pain, followed in some patients by vomiting and diarrhoea. These early symptoms are not unique to Ebola, so laboratory testing is important for diagnosis.
As of 6 November, there was no approved vaccine or specific treatment for Bundibugyo virus disease, although candidates were being studied. Early supportive care, including rehydration and treatment of symptoms, can improve a patient’s chances of survival. Alongside care, the response relies on identifying cases, tracing contacts and preventing infections in health facilities.
