The World Health Organisation (WHO) has warned that the Bundibugyo strain of Ebola virus detected in Nigeria has no licensed vaccine or approved specific treatment, heightening the importance of early detection and strict containment measures.
The warning follows Nigeria’s confirmation of an imported case of Bundibugyo Ebola virus disease in the Federal Capital Territory, Abuja, prompting intensified surveillance and contact-tracing efforts by health authorities.
The infected woman reportedly arrived in Nigeria from Uganda on October 3, 2026, and developed symptoms four days later. She sought medical attention at a private hospital in Abuja on October 11 before laboratory tests confirmed the infection on October 20.
Health officials said the patient had been transferred to an isolation facility for medical care, while investigations continued to establish how she contracted the virus.
No Approved Vaccine for the Bundibugyo Strain
According to the WHO, the Bundibugyo strain differs from the Ebola virus species targeted by the currently licensed Ebola vaccine.
Consequently, existing licensed Ebola vaccines cannot be assumed to provide protection against this particular strain. There is also no approved treatment specifically targeting Bundibugyo Ebola virus disease.
However, the absence of a strain-specific vaccine or treatment does not mean patients cannot receive medical care. Early diagnosis, isolation and supportive treatment remain essential in managing the disease and reducing the risk of further transmission.
Contact Tracing Underway in Abuja
The Federal Government, through the Nigeria Centre for Disease Control and Prevention (NCDC), has activated its emergency response system and commenced contact tracing.
Authorities initially identified 44 contacts linked to the infected patient, including healthcare workers, caregivers, other patients and individuals associated with her movements.
Public health teams are monitoring those identified and strengthening infection prevention measures at the healthcare facility where the patient initially received treatment.
The WHO is supporting Nigerian authorities with investigations, laboratory testing, contact tracing and measures to protect healthcare workers and communities.
Uganda Requests Patient’s Records
Meanwhile, Ugandan authorities have reportedly requested detailed travel and clinical records concerning the infected woman as investigations continue into the source of the infection.
Uganda has questioned whether the patient contracted the virus within its territory, maintaining that it had been declared Ebola-free following an earlier outbreak.
The request is expected to assist efforts to reconstruct the patient’s movements and exposure history before she arrived in Nigeria.
What Nigerians Should Know
Ebola spreads primarily through direct contact with the blood or bodily fluids of an infected person who is symptomatic, or through contaminated materials. It is not an airborne disease in the usual sense.
Early symptoms can include fever, fatigue, headache, muscle pain, sore throat, vomiting and diarrhoea.
