The Nigeria Centre for Disease Control and Prevention (NCDC) says Nigeria has recorded no new case of Ebola Virus Disease, with 28 contacts linked to the confirmed imported case still under surveillance.

The Director-General of the agency, Dr Jide Idris, disclosed this in a national health security update, explaining that 34 of the 62 contacts identified had completed their mandatory 21-day monitoring period as of November 9.

He said the remaining 28 contacts were still being monitored as part of efforts to prevent further transmission of the disease.

Nigeria confirmed its first imported case of Bundibugyo Virus Disease on October 20, involving a traveller from Uganda.

Idris clarified that being identified as a contact does not mean an individual has contracted the virus, stressing that the monitoring exercise is aimed at ensuring early detection and prompt medical intervention.

He said the NCDC, in collaboration with the Federal Ministry of Health and Social Welfare, state governments and development partners, had intensified surveillance, contact tracing, laboratory testing and monitoring at points of entry.

The agency urged healthcare workers to remain vigilant, obtain patients’ travel and exposure histories, observe infection prevention measures and promptly report suspected cases.

It also advised Nigerians who develop symptoms after possible exposure to Ebola to avoid contact with others and contact the NCDC through its toll-free line, 6232, for guidance.

Meanwhile, the agency raised concerns over other infectious diseases, including dengue fever, chikungunya, diphtheria, cerebrospinal meningitis and Lassa fever.

It confirmed dengue cases in Sokoto and Zamfara states, as well as chikungunya infections in Sokoto State.

The NCDC said response teams had been deployed to support affected states through disease surveillance, laboratory investigations, community engagement and mosquito control.

It called on Nigerians to remain alert and adopt preventive health practices, emphasising that early detection and timely reporting are essential to containing disease outbreaks.
