In a development that has raised regional public health alarms, Kenya has officially recorded its first confirmed case of Ebola, marking the first cross-border transmission of the rare Bundibugyo strain from the ongoing deadly outbreak in the Democratic Republic of the Congo (DRC). The patient was a Kenyan national who had resided in the DRC for seven years prior to his journey to the East African nation.
According to Kenya’s Health Minister Aden Duale, the man began showing symptoms of the virus approximately one month ago, and sought care at multiple medical facilities across the DRC before beginning his trip to Nairobi. His journey to Kenya followed an overland route from eastern DRC to Uganda’s capital Kampala, where he boarded a commercial flight bound for Nairobi on Saturday. Upon arrival at Nairobi’s main international airport, the patient passed through routine public health screenings without raising immediate concern, before being transported to a local city hospital by a family member.
After being admitted to Nairobi Hospital, the patient was quickly moved to a specialized isolation facility originally constructed during the global COVID-19 pandemic. It was at this facility that he developed the full suite of classic Ebola symptoms: high fever, chills, extreme fatigue and muscle weakness, painful difficulty swallowing, widespread muscle pain, and subcutaneous bleeding. Based on these telltale symptoms and the patient’s documented travel history from an active Ebola outbreak zone, attending clinicians immediately suspected a viral hemorrhagic fever and collected clinical samples for confirmatory testing. Those tests returned a positive result for the Bundibugyo strain of Ebola, Duale confirmed.
The patient succumbed to the virus at 23:30 local time on Monday (20:30 GMT), just days after arriving in Nairobi. His burial is scheduled for Tuesday, conducted in strict adherence to international public health safety protocols designed to prevent further transmission of the highly contagious virus.
As of Tuesday, Kenyan public health officials have identified at least 28 close contacts of the patient, including family members who accompanied him and healthcare workers involved in his treatment and care. Contact tracers are additionally working to locate and monitor 23 passengers and four crew members who were on the same commercial flight from Kampala to Nairobi as the infected patient.
The current outbreak of Bundibugyo Ebola, which the DRC first declared in May 2024, is already the second deadliest Ebola outbreak ever recorded. By the time the first case emerged in Kenya, the WHO had logged 8,463 confirmed cases across the DRC, with 4,082 confirmed deaths. Shortly after the outbreak was declared in the DRC, Uganda detected two cases, both of which were fatal. However, the World Health Organization officially declared Uganda free of Ebola transmission in August, and no additional cases had been recorded outside the DRC until Kenya’s confirmation this week.
Unlike the more common Zaire strain of Ebola, which has multiple approved vaccines and targeted treatments, the Bundibugyo strain is exceptionally rare and currently has no licensed vaccines or specific antiviral therapies available to combat infection. A small number of candidate medical countermeasures have been evaluated in clinical trials, but none have yet received full regulatory approval for widespread use.
