The Nigeria Centre for Disease Control and Prevention (NCDC) says it is monitoring 62 contacts linked to the country's confirmed Ebola case, with the exercise expected to be completed by November 13, 2026.

The latest development comes as Nigeria continues to strengthen its disease surveillance and response measures following the confirmation of an imported case of Ebola Virus Disease (EVD) on October 20.

According to the agency's latest Ebola Disease Situation Report, the 62 contacts identified are expected to complete their mandatory monitoring at different dates between October 31 and November 13.

The NCDC said contact tracing and monitoring remain ongoing, with additional contact tracers mapped and trained to strengthen surveillance and ensure that identified contacts complete the required follow-up period.

The agency also disclosed that 18 samples had been tested since the confirmation of the case, with one returning positive and 17 testing negative. The positive result was from the index patient, while the negative results included 15 samples collected from her contacts and two from other suspected cases.

Meanwhile, two additional suspected Ebola cases identified in northeastern Nigeria have also tested negative following laboratory investigations, according to the NCDC.

Nigeria's confirmed case involves a woman who recently travelled from Uganda to the country. She reportedly developed symptoms on October 7 and was subsequently diagnosed with the Bundibugyo strain of the Ebola virus.

The patient and her husband, who was identified as a close contact, were evacuated to Switzerland on October 26 for further medical care and monitoring.

As part of its response, the NCDC has activated the National Incident Management System, strengthened laboratory testing capacity and engaged the University of Abuja Teaching Hospital to improve its readiness as an isolation and treatment centre.

The agency is also reviewing its contact-tracing procedures, expanding surveillance and preparing to extend laboratory testing capacity to Lagos.

While the monitoring exercise is expected to end on November 13, the agency says surveillance and other response activities will continue.

The NCDC has urged continued vigilance as Nigeria works to prevent further transmission of the virus.
