Kenyan health authorities are tracing 57 people who may have had contact with the country’s first confirmed Ebola patient after the infected traveller passed through the Democratic Republic of Congo and Uganda before arriving in Nairobi.
The patient, a Kenyan citizen who had lived in Congo for seven years, was infected with the Bundibugyo species of the Ebola virus. Kenyan officials said he became ill while in Congo and received treatment there before travelling through several areas affected by the ongoing outbreak.
He travelled by road from the eastern Congolese city of Beni to Kampala, Uganda, despite restrictions at the Congo–Uganda border, and later boarded a flight to Nairobi on October 3. Officials are investigating how he crossed the border and passed health-screening procedures at airports in Entebbe and Nairobi.
The man was taken to Nairobi Hospital after arriving in Kenya, isolated and tested for Ebola. The Ministry of Health said he died on October 6.
Health Minister Aden Duale said the contact list had risen to 57 people, with 10 placed in quarantine. Authorities are attempting to locate the remaining contacts and are reviewing the flight manifest, airport surveillance recordings and health-declaration information.
The tracing operation includes passengers and crew members from the Kampala–Nairobi flight, employees who cleaned the aircraft, and immigration and customs officials who may have interacted with the patient. Authorities are also examining whether the aircraft was used for subsequent journeys.
Kenya’s government has stressed that the confirmed infection is an imported incident rather than evidence of an outbreak inside the country. No secondary infection linked to the patient had been officially confirmed at the latest update.
The case has nevertheless raised questions about regional disease surveillance. The traveller reportedly had symptoms before reaching Nairobi but registered a normal temperature during screening in Entebbe. Kenyan officials have said medication may have temporarily lowered his temperature before he was screened at Jomo Kenyatta International Airport.
Early Ebola symptoms can resemble those of other illnesses, while medication can make fever-based airport checks less reliable. Screening also depends on travellers accurately declaring their recent movements, symptoms and possible exposure.
Kenya has introduced a dedicated airport gate for passengers arriving from countries connected to the outbreak and is strengthening surveillance at land crossings and other entry points. Authorities have designated five health facilities with 241 isolation beds and are working to expand available capacity.
The World Health Organization said Kenya had screened more than 652,000 incoming travellers, tested 267 suspected samples and trained almost 5,000 health workers in prevention and case management by October 6. WHO and Africa CDC are assisting Kenya, Congo and Uganda with surveillance and contact tracing.
The imported case originated during Congo’s most severe Ebola emergency in years. Data compiled through October 4 recorded more than 8,600 confirmed infections and over 4,100 deaths in the country. The outbreak involves the Bundibugyo virus species and has spread beyond its initial centre in northeastern Congo.
Ebola spreads through direct contact with the blood or other bodily fluids of an infected person, contaminated materials or the body of someone who has died from the disease. It is not transmitted through ordinary casual contact with someone who has no symptoms.
Kenya’s immediate risk will depend on whether officials identify and monitor every person exposed during the patient’s journey. Until those investigations are complete, reporting should distinguish the single confirmed imported case from any suggestion of sustained transmission inside Kenya.
