October 23, 2026 â Health officials are investigating whether Ebola patients from Nigeria and Kenya crossed paths at Uganda’s Entebbe International Airport on October 3, raising concerns about cross-border transmission as a major outbreak continues in the Democratic Republic of the Congo (DRC).
The Africa Centres for Disease Control and Prevention (Africa CDC) is examining whether the patients shared airport facilities, equipment or another possible source of exposure. Officials stress that no direct contact or transmission link has been confirmed.
Kenya has reported nine infections and one death, while Nigeria has confirmed its first Ebola case in more than a decade.
Uganda Airport Investigation Focuses on October 3
The Kenyan patient travelled from the DRC through Uganda to Nairobi. The Nigerian patient, a 42-year-old Ugandan-born woman living in Abuja, returned from Uganda through Ethiopia. Both passed through Entebbe airport on October 3.
Dr Wessam Mankoula, Africa CDC’s emergency preparedness and response chief, said investigators were examining possible interaction between the cases.
Authorities are also considering whether the infections could have originated from another common source. Sharing an airport does not establish Ebola exposure.
The investigation highlights the importance of tracing international travel during infectious disease outbreaks. A separate measles outbreak in Canada involving flight exposure alerts illustrates how authorities identify potentially exposed travellers. Unlike measles, Ebola does not spread through ordinary airborne transmission.
Nigeria Ebola Patient: Travel History and Health Update
Nigeria’s patient is married to a Swiss diplomat and spent approximately two and a half weeks in Uganda before returning to Abuja on October 3.
Her journey included a two-hour stopover in Addis Ababa, Ethiopia. She developed symptoms on October 7 and received care at two private healthcare facilities before testing positive for Bundibugyo Ebola on October 20.
The woman remains isolated and is reportedly improving. Her husband, who accompanied her during the trip, is also isolated but has not developed symptoms.
Authorities initially identified 44 possible contacts, mainly healthcare workers and relatives. Additional contacts are being investigated.
Nigeria is prioritising genomic sequencing to help determine the infection’s origin.
Ugandan officials previously suggested the woman visited eastern Congo, but WHO and Africa CDC have not verified that claim.
Kenya Confirms Nine Ebola Cases and One Death
Kenya’s first patient arrived in Nairobi on October 3 after travelling from Congo through Uganda. He subsequently died, becoming the country’s first Ebola fatality during the current outbreak.
Eight additional infections were identified among people connected to the original patient.
Kenyan health officials say the surviving patients remain isolated and are responding to treatment. No wider community transmission has been identified.
The first quarantined contacts are expected to complete their 21-day monitoring period beginning October 25, provided they remain symptom-free.

Congo Ebola Outbreak Claims Thousands of Lives
The outbreak began in May 2026 in the DRC and involves the Bundibugyo virus.
Figures reported through October 20 indicate more than 9,600 confirmed infections and 4,600 deaths across eight provinces.
Conflict, population displacement and limited healthcare access have complicated containment efforts, particularly in eastern Congo.
There is currently no licensed vaccine or specific approved antiviral treatment for Bundibugyo Ebola. Early supportive medical care remains essential.
Uganda Tightens Screening as International Concerns Grow
Uganda says it has no active confirmed Ebola cases and has strengthened surveillance at airports and border crossings.
Authorities have warned that travellers concealing symptoms or violating public-health requirements could face legal consequences.
The United States has tightened travel precautions linked to affected areas, while regional health agencies are strengthening contact tracing and laboratory surveillance.
The World Health Organization’s Nigeria Ebola update provides official information about the confirmed infection and public-health response.
Ebola Symptoms and Precautions for Travellers
Ebola spreads through direct contact with infected blood, bodily fluids or contaminated objects. It does not spread through the air like influenza.
Symptoms can develop between two and 21 days after exposure and include fever, weakness, headache, vomiting and diarrhoea.
People who develop symptoms after travelling through affected areas should seek medical guidance promptly and disclose their travel history.
Identifying possible exposure is also important in other public-health investigations. A separate E. coli outbreak investigation at a Calgary water park illustrates how authorities identify exposure periods and advise people to monitor symptoms. The diseases have different transmission routes.
Investigators are reconstructing both patients’ movements and examining genetic evidence. Until those findings are available, the suspected airport connection remains unconfirmed.
