Nigeria has intensified surveillance and preparedness measures against the possible importation of Ebola Virus Disease following the continued spread of the Bundibugyo virus in the Democratic Republic of the Congo, with the Nigeria Centre for Disease Control and Prevention placing the country on high alert.
The latest measures include enhanced monitoring of travellers arriving from countries with active or relevant Ebola transmission, strengthened follow-up arrangements and the use of Nigeria’s Health Declaration Form for travellers from affected countries. The NCDC has also urged Nigerians to remain vigilant and to seek medical attention promptly if symptoms consistent with Ebola develop, particularly where there is a relevant travel or exposure history.
The heightened response comes as the outbreak in the Democratic Republic of the Congo continues to expand. The World Health Organization’s latest detailed disease-outbreak update available before the NCDC’s September advisory reported thousands of confirmed Bundibugyo virus cases and deaths across multiple provinces, while WHO continues to classify the outbreak as a Public Health Emergency of International Concern.
Nigerian authorities have stressed that the current alert is a preparedness and surveillance response to a regional outbreak, rather than an announcement of an Ebola outbreak inside Nigeria.
No Confirmed Nigerian Case Reported
The NCDC has continued to state that Nigeria has no confirmed case of Ebola associated with the current regional outbreak. The agency previously warned that the risk of importation was high because of continuing regional transmission, international travel, population movement, major airports, seaports, land borders and informal crossing routes.
That distinction is important for public understanding of the current situation.
Nigeria’s high-alert status does not mean that an outbreak has been confirmed in the country. Instead, it reflects the measures being taken by public-health authorities to identify a potential imported infection quickly and prevent onward transmission if a suspected case is detected.
The NCDC’s current approach follows the same broad principle used in infectious-disease preparedness: strengthen surveillance before an imported case is detected, maintain the ability to investigate suspected cases and ensure that health workers and response institutions are prepared to act rapidly if necessary.
The Federal Ministry of Health and Social Welfare has also previously confirmed that Nigeria was strengthening preparedness through surveillance, screening at points of entry, laboratory readiness, infection-prevention measures and coordination with state health authorities.
Why Nigeria Is Watching the DRC Outbreak Closely
The current concern is linked to the scale and geographic spread of the Bundibugyo virus outbreak in the Democratic Republic of the Congo.
In its September 10 Disease Outbreak News update, WHO reported that the outbreak had expanded to 61 health zones across six provinces of the DRC. As of September 7, the country had reported 6,757 confirmed cases and 3,267 deaths, giving a crude case-fatality ratio of 48.3 per cent among confirmed cases.
WHO also reported that the outbreak was not confined to a single location. Ituri remained the most affected province, while cases had also been recorded in North Kivu, Haut-Uélé, Tshopo, Bas-Uélé and South Kivu.
The geographic expansion has increased concern about cross-border transmission.
WHO said surveillance and screening activities were continuing at airports, ports and official land border crossings, while informal crossings remained a challenge because people and goods can move through routes that are not subject to the same level of health monitoring. The organisation therefore stressed the importance of strengthened cross-border coordination and sustained surveillance and preparedness.
Nigeria is geographically distant from the principal affected areas in eastern and northeastern DRC, but it is connected to the wider African region through extensive air travel, commerce, migration and other forms of movement.
For public-health authorities, that makes preparedness relevant even when there is no direct border with an affected country.
The Virus Involved
The current outbreak involves Bundibugyo virus, a species of Ebola virus.
This is significant because Bundibugyo virus is distinct from the Zaire ebolavirus associated with several previous major Ebola outbreaks. WHO says there is currently no licensed vaccine specifically approved for prevention of Bundibugyo virus disease and no specific licensed treatment for the disease, although research into vaccines and treatments is under way.
WHO reported that the licensed Ebola vaccine Ervebo was being considered within research and outbreak-response contexts, but available evidence did not establish its effectiveness against Bundibugyo virus disease for routine preventive use. WHO’s August assessment therefore recommended that Ervebo be used for Bundibugyo virus disease only within a research protocol at that stage.
The absence of a licensed vaccine specifically for Bundibugyo virus places additional importance on the basic tools of outbreak control.
Those tools include early detection, laboratory confirmation, isolation and clinical management of suspected and confirmed cases, infection prevention and control in health facilities, contact tracing, safe and dignified management of deaths, community engagement and accurate public communication.
Nigeria’s Health Declaration Measures
One of the measures highlighted by the NCDC is the use of the Health Declaration Form for travellers arriving from countries with active or relevant Ebola transmission.
The NCDC’s health declaration system collects information including personal details, travel history, countries visited, transit locations, destination information and recent symptoms. The form also asks about possible contact with people who have been unwell and whether the traveller was ill before boarding or during the journey.
The system provides health authorities with information that can assist disease surveillance and follow-up after arrival.
The current NCDC Ebola advisory specifically directs travellers arriving from countries with active or relevant EVD transmission to complete the Health Declaration Form as part of enhanced surveillance and follow-up measures. The agency said passengers from other countries were exempt from completing the Ebola-specific requirement at the time of the advisory.
The health declaration process is therefore being used as part of a broader surveillance system rather than as a diagnosis tool.
Completing a form does not mean that a traveller has Ebola. It allows health authorities to identify relevant travel and health information that may be important if symptoms develop or if an exposure is subsequently identified.
What Travellers Should Understand
The NCDC’s current guidance places particular importance on travel history and symptoms.
The Nigeria Health Declaration Form asks travellers about symptoms experienced during the previous 21 days. These include fever, cough, general weakness or feeling unwell, rash, difficulty breathing, jaundice, nose or ear bleeding, headache, body aches, sore throat, difficulty swallowing, abdominal pain, vomiting, diarrhoea, lethargy, loss of appetite and hiccups.
The form also asks about possible contact with people who were unwell and whether the traveller became ill before boarding or during the journey.
Such questions are designed to help public-health officials identify people who may require additional assessment.
They do not mean that any one of these symptoms automatically indicates Ebola.
Fever, headache, weakness, body aches, vomiting and diarrhoea can occur with numerous infectious and non-infectious conditions, including diseases that are common in Nigeria. The NCDC has previously cautioned Nigerians against assuming that every fever-related illness is Ebola and stressed the importance of clinical assessment, exposure history and laboratory testing.
Ebola Symptoms Can Overlap With Other Diseases
One of the difficulties in responding to Ebola is that some early symptoms can resemble those of other illnesses.
The NCDC has previously identified fever, weakness, headache, muscle pain, sore throat, vomiting and diarrhoea among symptoms that may occur with Ebola, while severe disease can involve bleeding.
In Nigeria, however, several other illnesses can produce similar early symptoms.
Malaria is widespread, while Lassa fever and other infectious diseases can also cause fever and systemic symptoms. That means diagnosis cannot be based simply on the presence of fever or another individual symptom.
The NCDC has therefore emphasised the importance of travel history, exposure history, case definitions and laboratory investigation when Ebola is suspected.
For members of the public, the practical message is straightforward: people who become seriously ill, particularly after relevant travel or possible exposure, should seek medical attention promptly and provide healthcare workers with accurate information.
How Ebola Spreads
Ebola is primarily transmitted through direct contact with the blood or other bodily fluids of an infected person or someone who has died from the disease. Transmission can also occur through contaminated materials.
This is different from diseases that spread efficiently through the air over long distances.
The distinction matters because public-health measures are designed around the known routes of transmission.
Infection prevention and control practices in healthcare settings are particularly important. Health workers caring for suspected or confirmed patients can face exposure to infectious bodily fluids if appropriate protective procedures are not followed.
WHO has repeatedly highlighted the importance of infection prevention and control, early recognition and rapid isolation in limiting Ebola transmission within households and healthcare facilities.
The NCDC has similarly emphasised the need for healthcare workers in Nigeria to maintain preparedness, recognise suspected cases and apply infection-prevention measures.
The Importance of Frontline Health Workers
A potential imported Ebola case would present a particular challenge for healthcare facilities because the first symptoms can resemble other diseases.
A patient with fever, weakness, vomiting or diarrhoea may initially present at a general hospital or primary healthcare centre rather than an infectious-disease treatment facility.
If a relevant travel or exposure history is not identified quickly, healthcare workers could be exposed before the possibility of Ebola is recognised.
This is one reason preparedness measures extend beyond airports.
Nigeria’s earlier public-health planning has included guidance for viral haemorrhagic fevers, Ebola surveillance, case definitions, infection prevention and control and procedures for contact tracing. The NCDC maintains a collection of guidelines and protocols covering Ebola preparedness and response.
The agency’s May 2026 preparedness advisory also stressed the need for every state and the Federal Capital Territory to be able to detect, contain and respond quickly to suspected cases while protecting health workers and maintaining essential health services.
That approach reflects an important principle in epidemic response: national preparedness is only effective if local facilities can recognise and report unusual illness quickly.
Nigeria’s Experience With Ebola
Nigeria’s current preparedness measures also draw on the country’s experience during the 2014 Ebola outbreak.
Nigeria detected Ebola after an infected traveller from Liberia arrived in Lagos in July 2014. The country subsequently used contact tracing, isolation, surveillance and coordinated public-health measures to contain the outbreak.
The experience has remained an important reference point for Nigeria’s public-health preparedness.
The NCDC’s current Director-General, Jide Idris, previously led the Lagos State response team during the 2014 Ebola outbreak. The NCDC’s official biography notes his role in the rapid containment of that outbreak and his subsequent involvement in strengthening pandemic-response capacity.
The 2014 response also demonstrated why rapid identification of contacts and clear communication can be important during a high-consequence infectious-disease event.
Nigeria’s authorities are now attempting to maintain those capabilities before an imported case occurs rather than waiting until transmission has already begun.
Why Preparedness Begins Before a Case
Public-health preparedness can appear excessive when no case has been confirmed.
However, the objective is to prevent a suspected imported infection from becoming a chain of transmission.
If a traveller arrives while incubating an infectious disease, symptoms may not be present at the point of entry. This means that airport screening alone cannot identify every possible case.
That is why the NCDC’s current approach combines point-of-entry surveillance with follow-up and public-health monitoring.
The Health Declaration Form contains information that can be used for follow-up, while the system asks travellers to acknowledge a 21-day post-arrival monitoring process.
The monitoring period is linked to the need to observe people who may have had relevant exposure and to encourage prompt reporting if symptoms emerge.
The broader strategy is therefore based on several layers rather than one single screening measure.
Surveillance at Airports, Seaports and Land Borders
Nigeria’s international connectivity means that surveillance at points of entry remains a major component of disease preparedness.
Earlier federal health measures included enhanced screening at airports, seaports and land borders, strengthened surveillance and monitoring, laboratory readiness and the mobilisation of rapid-response structures.
The current Ebola alert builds on those systems.
Nigeria’s borders include major international airports as well as seaports and numerous formal and informal land routes. Public-health authorities have previously identified population movement, trade routes and informal crossings as factors that complicate the monitoring of infectious diseases.
The challenge is not simply stopping people from travelling.
Rather, effective disease surveillance requires identifying relevant travel histories, recognising symptoms, ensuring that suspected cases can be assessed safely and maintaining communication between national, state and local health authorities.
The Situation in the Democratic Republic of the Congo
The scale of the outbreak in the DRC explains why regional preparedness remains a priority.
WHO’s September 10 report recorded 6,757 confirmed cases and 3,267 deaths in the DRC as of September 7. Cases had been identified across 61 health zones in six provinces.
WHO said 51 of those health zones had reported at least one case during the preceding 21 days, indicating that transmission remained active across a substantial portion of the affected areas.
Ituri remained the epicentre, accounting for 5,406 confirmed cases in the WHO report.
The organisation also noted that insecurity, displacement, overcrowding and limited access to healthcare and sanitation were complicating the response in some affected communities.
These factors can delay the identification of cases and make contact tracing and infection-control measures more difficult.
WHO has also warned that continued transmission and population movement increase the possibility of cross-border spread.
Uganda and Wider Regional Movement
The current outbreak has not been confined to the DRC.
Earlier WHO updates documented cases in Uganda linked to the wider outbreak. By the end of August, WHO reported that Uganda had completed the required enhanced monitoring period after its most recent case, while continuing to monitor developments in the region.
The movement of people between countries is a normal feature of economic and social life across Africa, but it can complicate outbreak control when an infectious disease is circulating.
For Nigeria, the lesson is not that every traveller from another African country represents a threat. Rather, public-health agencies use travel information to determine where enhanced surveillance may be appropriate.
This is why the NCDC has linked its current measures to countries with active or relevant Ebola transmission rather than applying the same Ebola-specific requirements to every traveller regardless of travel history.
Public Communication Remains Critical
The NCDC has also emphasised the importance of reliable information.
Public-health emergencies can generate misinformation, particularly when people encounter alarming reports on social media before official agencies have completed verification.
Earlier this year, the NCDC warned Nigerians against misinformation about Ebola and clarified that Nigeria had not recorded a confirmed case associated with the current regional outbreak.
The agency also explained that Ebola and other diseases such as Hantavirus are distinct illnesses with different transmission patterns, while cautioning against unverified claims about supposed home remedies or treatments.
Accurate communication matters for two reasons.
First, unnecessary panic can place pressure on health facilities and make it more difficult for authorities to distinguish genuine alerts from rumours.
Second, false reassurance can be equally dangerous if people with genuine symptoms or relevant exposure delay seeking care.
The public-health objective is therefore neither panic nor complacency, but informed vigilance.
What Nigerians Can Do
The NCDC’s advice includes maintaining good hand hygiene, avoiding direct contact with the bodily fluids of sick people and promptly reporting unusual illness.
People who become ill after relevant travel should tell healthcare workers where they have travelled and whether they may have had contact with an infected or unwell person.
Accurate information can help clinicians determine whether a patient needs additional assessment for a viral haemorrhagic fever.
Members of the public should also avoid spreading unverified claims about suspected Ebola cases.
A report circulating online is not equivalent to laboratory confirmation.
The appropriate response to a suspected case is notification through established health channels, investigation and testing by the relevant authorities.
What Healthcare Facilities Are Expected to Do
Healthcare workers are an important part of the country's early-warning system.
The NCDC has previously advised healthcare personnel to maintain a high level of awareness, apply appropriate infection-prevention and control procedures and promptly report suspected cases through established public-health channels.
Health facilities must also protect staff while evaluating patients.
If Ebola is suspected, infection-control measures become particularly important because transmission can occur through direct exposure to bodily fluids.
Early recognition can allow a patient to be referred or isolated appropriately while health authorities investigate contacts and arrange laboratory testing.
These measures are not unique to Ebola. They form part of the wider system for dealing with viral haemorrhagic fevers and other high-consequence infectious diseases.
Why Laboratory Capacity Matters
Symptoms alone cannot establish an Ebola diagnosis.
Laboratory testing is necessary to confirm or exclude the disease.
That makes laboratory preparedness an important part of Nigeria’s response architecture. The Federal Ministry of Health has previously identified strengthened laboratory and diagnostic capacity as one of the measures activated in response to the regional Ebola threat.
Laboratory systems must operate alongside surveillance and clinical systems.
A test is useful only when suspected cases are identified, samples are collected safely, transported appropriately and results are returned quickly enough to guide public-health action.
This is why the NCDC has described preparedness as a combination of surveillance, laboratory readiness, emergency response, infection prevention and public communication.
What Happens If a Suspected Case Is Detected?
If a suspected Ebola case were identified in Nigeria, the response would involve several stages.
First, the patient would require appropriate clinical assessment and infection-control precautions.
Health authorities would investigate the patient's symptoms, travel history and possible exposure.
A sample would then be tested through the appropriate laboratory network.
Depending on the findings, public-health teams could begin identifying and monitoring people who had relevant contact with the patient.
The response would also involve risk communication to affected communities and healthcare facilities.
The exact operational response would depend on the circumstances of the suspected case and the results of laboratory investigation.
It would therefore be inappropriate to assume that every person flagged by screening would have Ebola or that every traveller with a fever would require the same response.
Preparedness Measures Are Subject to Review
The NCDC has indicated that its measures will be reviewed as the epidemiological situation changes.
That is a standard feature of outbreak response.
If transmission in affected countries increases or decreases, or if new countries report cases, the risk assessment may change. Travel requirements, surveillance arrangements and other measures can therefore be adjusted according to available evidence.
The NCDC said the current measures followed a dynamic risk assessment conducted in consultation with public-health experts and the Federal Ministry of Health and Social Welfare.
The agency has also emphasised evidence-based surveillance and preparedness rather than relying on rumours or unverified reports.
No Reason to Confuse Alert With Outbreak
The distinction between an alert and an outbreak remains central to understanding the latest development.
Nigeria is on high alert because authorities assess that there is a significant enough regional risk to justify enhanced preparedness.
That does not establish that Ebola is circulating in Nigerian communities.
As of the latest NCDC public communications reviewed for this report, the agency continues to state that Nigeria has no confirmed case associated with the current regional outbreak.
At the same time, the absence of a confirmed Nigerian case does not mean that preparedness measures are unnecessary.
Infectious diseases can cross borders through travel and population movement, and public-health agencies therefore seek to identify risks before local transmission begins.
What Happens Next
The immediate next step is continued surveillance.
The NCDC is expected to monitor developments in the DRC and other affected areas, assess travel-related risks and adjust preparedness measures as necessary.
Point-of-entry surveillance will remain important, particularly for travellers arriving from countries with active or relevant Ebola transmission.
Healthcare facilities will also need to maintain awareness of viral haemorrhagic fevers and continue following infection-prevention procedures.
Public communication will remain part of the response, particularly if new information emerges about the outbreak or travel-related risks.
WHO, meanwhile, continues to support response activities in the DRC, including surveillance, contact tracing, clinical preparedness, infection prevention and control, community engagement and research into medical countermeasures.
The Broader Public-Health Lesson
The current situation illustrates how disease surveillance operates across national borders.
A disease outbreak does not need to occur inside Nigeria before Nigerian authorities begin preparing for it.
Monitoring international outbreaks, strengthening laboratories, maintaining trained response teams, improving border surveillance and communicating accurate information are all part of preventive public health.
Nigeria’s experience in 2014 remains relevant because the country previously demonstrated the importance of rapid response after an imported Ebola case.
The current response is taking place under different circumstances, with a different Ebola species and a much larger outbreak in the DRC, but the basic public-health principle remains similar: early recognition and rapid action can reduce opportunities for transmission.
Public Vigilance Without Panic
For Nigerians, the latest health alert means that people should remain informed and attentive without assuming that every fever or illness is Ebola.
The NCDC has advised people to seek medical attention promptly when symptoms consistent with Ebola occur, particularly where there is a relevant travel or exposure history.
Travellers affected by the current Health Declaration requirements should provide accurate information about recent travel and health status.
Healthcare workers should continue to apply infection-prevention measures and report suspected cases through the established surveillance system.
And the public should rely on verified information from the NCDC, Federal Ministry of Health, WHO and other recognised health authorities when assessing developments.
Nigeria Watches the Regional Outbreak
The latest warning from the NCDC comes as the Bundibugyo Ebola outbreak in the DRC continues to pose a significant regional public-health challenge.
WHO’s latest detailed update before this report showed that the outbreak had reached 61 health zones across six provinces, with 6,757 confirmed cases and 3,267 deaths reported in the DRC as of September 7.
Nigeria has responded by strengthening surveillance and preparedness, including targeted use of the Health Declaration Form for travellers arriving from countries with active or relevant Ebola transmission.
The NCDC continues to state that Nigeria has no confirmed case associated with the current regional outbreak.
The immediate task for health authorities is therefore preparedness: detecting any potential imported case quickly, protecting healthcare workers, maintaining laboratory capacity, monitoring travellers and keeping the public informed.
For the public, the guidance remains centred on accurate information, prompt medical attention for concerning illness and appropriate hygiene practices.
The situation will continue to be monitored as the outbreak in Central Africa evolves.
For now, Nigeria’s high-alert posture represents an intensified preparedness response to a regional Ebola threat, not confirmation of an Ebola outbreak inside the country.
