The headline has been refined to include relevant search terms such as Ebola outbreak update, NCDC and Ebola surveillance in Nigeria, while preserving the central development in the original report.
The Nigeria Centre for Disease Control and Prevention (NCDC) has confirmed that 28 people linked to Nigeria’s imported Ebola case remain under public health surveillance, while 34 others have completed their individual 21-day monitoring period.
The latest figures were disclosed by the agency’s Director-General, Dr Jide Idris, in a national health security update released on Tuesday, November 10, 2026. The update provides an important assessment of Nigeria’s response to the Bundibugyo virus disease case confirmed in October.
According to Idris, health authorities have identified 62 contacts associated with the confirmed infection. Of this number, 34 have completed the required monitoring period, leaving 28 individuals under continued observation.
The NCDC stressed that no additional confirmed Ebola cases had been recorded as of November 9, despite continued investigations into suspected cases and alerts reported across the country.
The development represents progress in the country’s contact-tracing exercise, although the remaining individuals must complete their respective monitoring periods before health authorities can conclude their follow-up.
Idris explained that the surveillance process is designed to identify possible symptoms early and ensure that anyone who develops signs of infection receives appropriate medical attention.
He also cautioned Nigerians against assuming that everyone identified as an Ebola contact has contracted the virus. Contact identification is a public health precaution that allows health officials to monitor individuals who may have been exposed to an infected person.
The agency said its response remains active, with surveillance, laboratory investigations and other preventive measures continuing in collaboration with federal and state health authorities.
The latest figures are particularly important because Nigeria is dealing with an imported case of Bundibugyo virus disease, a form of Ebola caused by a distinct virus species. The infection was confirmed in a traveller who arrived in Nigeria from Uganda.
Although the absence of additional confirmed infections is encouraging, the NCDC has maintained that the country must continue monitoring contacts and investigating reported alerts.
According to the agency’s official outbreak dashboard, Nigeria had one confirmed case, no recorded deaths, 62 identified contacts, 28 people still under follow-up and 34 who had completed monitoring as of November 10, 2026. NCDC Outbreak Updates+2
How Nigeria’s Ebola outbreak started
Nigeria’s current Ebola surveillance response followed the confirmation of an imported Bundibugyo virus disease infection in October 2026.
The index patient was a 42-year-old woman who travelled to Nigeria from Uganda through Addis Ababa. According to information contained in the NCDC’s situation report, she arrived in Abuja on October 3, 2026.
She reportedly developed symptoms on October 7 and was admitted to a private healthcare facility on October 11. Health authorities were notified on October 19, prompting an investigation and the collection of samples for laboratory testing.
The National Reference Laboratory confirmed the infection on October 20.
The confirmation triggered an emergency public health response involving the NCDC, the Federal Ministry of Health and Social Welfare, the Federal Capital Territory Administration and other relevant partners.
Health officials immediately began identifying people who might have had contact with the infected traveller during the relevant exposure period.
The patient was subsequently evacuated to Switzerland for further treatment, according to previous reports on the outbreak.
The identification of 62 contacts formed an important part of the response because Ebola can spread through direct contact with the blood and other bodily fluids of an infected person, particularly when symptoms are present.
Contact tracing helps health authorities identify people who may have been exposed, establish their risk levels and monitor their health during the incubation period.
The NCDC’s response has therefore focused on ensuring that potential infections are detected before they can lead to further transmission.
The agency has also maintained surveillance at international airports and land borders to identify travellers who may develop symptoms after arriving in Nigeria. Nigeria Centre for Disease Control+2
Why 28 contacts are still being monitored
One of the most important aspects of the NCDC’s announcement is the distinction between the 21 days since the first confirmed infection and the individual monitoring period assigned to each contact.
The incubation period for Ebola is generally between two and 21 days. This means symptoms may develop within that period following exposure to the virus.
However, the monitoring period is calculated individually because people may have had contact with an infected person at different times.
Consequently, the completion of 21 days since Nigeria confirmed its first case does not automatically mean that every identified contact has completed surveillance.
Idris explained that the remaining 28 contacts would not necessarily complete their monitoring simultaneously because their individual follow-up periods depend on their respective exposure timelines.
He also warned that Nigeria should not be declared Ebola-free simply because 34 people have completed monitoring and no additional infections have been confirmed.
The NCDC chief said the World Health Organization would have to be involved in determining when the country could officially be declared free of the outbreak.
His clarification is important because premature declarations could create a false sense of security while some individuals remain under observation.
The agency has therefore maintained its monitoring activities while awaiting the completion of the outstanding follow-up periods. Punch Newspapers+2
NCDC strengthens Ebola surveillance across Nigeria
Beyond monitoring the 28 remaining contacts, the NCDC has continued implementing several measures to prevent further transmission.
These include contact tracing, investigation of reported alerts, laboratory testing, infection prevention and control, safe clinical care and surveillance at points of entry.
The agency is working with the Federal Ministry of Health and Social Welfare, the Federal Capital Territory Administration, state governments and development partners to coordinate the response.
Surveillance at airports and land borders remains particularly important because the confirmed infection was imported by a traveller arriving from Uganda.
The NCDC has also been investigating suspected cases reported in different parts of the country.
According to Idris, alerts received from Adamawa, Rivers and Borno states were investigated, with the suspected cases testing negative.
The agency has encouraged healthcare facilities to maintain vigilance and promptly report individuals presenting symptoms that could indicate Ebola, particularly where there is a relevant travel or exposure history.
Healthcare workers have also been advised to maintain appropriate infection prevention and control procedures when handling suspected cases.
These measures are important because early identification and proper isolation of suspected infections can reduce opportunities for further transmission.
Nigeria’s outbreak response dashboard also provides regular information about confirmed cases, contacts under monitoring, laboratory findings and screening activities at points of entry.
As of November 10, the NCDC reported that 659,429 travellers had been screened through its health declaration and entry surveillance arrangements since June 5, 2026. The agency also reported screening 5,907 people on November 9 alone. NCDC Outbreak Updates+1
What Nigerians should know about Ebola symptoms and transmission
The NCDC has continued urging Nigerians to understand how Ebola spreads and recognise symptoms that may require medical attention.
Ebola is a severe viral disease that can cause serious illness and death. It is transmitted through direct contact with the blood or other bodily fluids of an infected person who is showing symptoms.
Transmission can also occur through contaminated objects, including clothing, bedding, medical equipment and needles.
Unsafe burial practices involving the body of someone who died from Ebola can also expose other people to the virus.
Common symptoms include fever, severe headache, muscle pain, weakness, vomiting and diarrhoea. Some patients may also experience unexplained bleeding.
However, these symptoms can occur in other illnesses, meaning that experiencing a fever or body pain does not automatically indicate Ebola infection.
People who develop symptoms after possible exposure should avoid contact with others and seek guidance from public health authorities immediately.
The NCDC has advised individuals who suspect possible exposure or develop concerning symptoms to contact its toll-free emergency line on 6232 for guidance.
The agency has also emphasised that Ebola does not spread through casual contact with people who are not showing symptoms.
This distinction is important in preventing unnecessary panic, discrimination and the stigmatisation of people identified during contact-tracing exercises.
The public is encouraged to follow information from recognised health authorities rather than rely on unverified social media messages or rumours about suspected infections. NCDC Outbreak Updates+1
Nigeria remains on alert despite the absence of new cases
Although Nigeria has not confirmed another Ebola infection since the October 20 diagnosis, the NCDC has maintained that the public health response is not yet complete.
The 28 contacts still under monitoring remain part of the surveillance exercise, and the agency must continue investigating reported alerts to determine whether they represent genuine infections.
The development also highlights the importance of maintaining a strong public health system capable of responding to imported infectious diseases.
Nigeria’s international travel connections make border surveillance, laboratory capacity and rapid communication between healthcare facilities particularly important.
The Ebola response has also placed renewed attention on the need for healthcare workers to recognise unusual symptoms, establish patients’ travel histories and follow appropriate infection prevention procedures.
For members of the public, the immediate priority is to remain informed without creating unnecessary fear.
The completion of monitoring by 34 contacts is a positive development in the ongoing response, but it should not be confused with an official declaration that Nigeria is Ebola-free.
The NCDC says surveillance will continue until the remaining contacts have completed their individual follow-up periods and the relevant public health authorities have assessed the situation.
Nigerians can follow verified updates through the Nigeria Centre for Disease Control and Prevention and its official Ebola outbreak dashboard.
For now, the agency’s message remains clear: there are no additional confirmed cases as of November 9, 2026, but continued vigilance, early reporting and cooperation with health authorities remain essential to preventing further transmission.
