ABUJA — Nigeria has raised its public-health readiness to a higher level following the worsening outbreak of Bundibugyo Ebola virus disease in the Democratic Republic of Congo (DRC), with the Nigeria Centre for Disease Control and Prevention (NCDC) placing the country on high alert over the risk of importation.
But there is an important distinction: Nigeria has not reported a confirmed case from the current outbreak.
The immediate concern is therefore not an outbreak already spreading across Nigeria, but whether the country can detect and contain an imported case quickly enough if one occurs.
The question is increasingly important as the DRC outbreak continues to expand.
The World Health Organisation (WHO), in its latest detailed situation report, said that as of September 7, the DRC had recorded 6,757 confirmed cases and 3,267 deaths, representing a crude case-fatality ratio of 48.3 per cent.
The outbreak had spread across 61 health zones in six provinces, with evidence of continued transmission and geographical expansion. WHO has assessed the risk as very high inside the DRC, high for countries sharing land borders with the DRC, and low for the rest of Africa and globally.
Nigeria does not share a border with the DRC.
Yet its extensive international travel connections, major airports and seaports, population movement and informal border routes have made preparedness a national priority.
THE WARNING FROM NCDC
In its national public-health advisory issued in May, the NCDC assessed Nigeria’s overall risk of Ebola importation as HIGH.
The agency attributed the assessment to continuing regional transmission, international travel, population movement, major airports and seaports, porous land borders, informal crossings and trade routes.
The agency also warned that early Ebola symptoms can resemble common illnesses such as malaria and Lassa fever, creating a potential challenge for early recognition.
NCDC has activated the national Emergency Operations Centre in alert mode and directed states to strengthen their preparedness systems.
The agency’s warning is significant because the most important period in an Ebola response may be before the first confirmed case.
TEN STATES AND THE FCT UNDER HIGH-RISK WATCH
NCDC has divided the country into three preparedness categories.
The high-risk group consists of:
Lagos, FCT, Rivers, Kano, Enugu, Borno, Akwa Ibom, Cross River, Taraba and Adamawa.
NCDC says these states have characteristics including international airports or seaports, major travel and trade routes, porous borders or significant population movement.
A second group — including Ogun, Nasarawa, Kaduna, Plateau, Kogi, Niger, Jigawa, Katsina, Bauchi, Ebonyi, Abia and Bayelsa — has been classified as moderate risk.
All other states remain under baseline preparedness.
But NCDC makes clear that baseline does not mean no preparedness.
Every state is expected to be capable of identifying a suspected case, isolating the patient safely, notifying the appropriate authorities and supporting contact tracing.
THE VACCINE QUESTION
Perhaps one of the most important differences between the present outbreak and the Ebola crisis Nigerians remember from 2014 is the virus involved.
The current outbreak is caused by Bundibugyo virus, a different Ebola virus species from the Zaire ebolavirus responsible for the major 2014 West African epidemic.
NCDC says there are currently no approved vaccines or specific treatments for Bundibugyo Ebola.
WHO says the licensed Ervebo vaccine, which targets Zaire ebolavirus, is being studied for possible use against Bundibugyo virus, but current evidence is insufficient to support routine preventive use. WHO recommends its use against Bundibugyo only within a research protocol.
That makes early detection, isolation, infection prevention and supportive medical care particularly important.
WHAT HAPPENS IF A SUSPECTED CASE APPEARS?
NCDC’s preparedness plan requires states to identify at least one functional holding or isolation facility for suspected cases.
They are also expected to establish clear referral arrangements, strengthen infection-prevention measures, ensure appropriate protective equipment for frontline workers, prepare for safe sample transportation and improve contact-tracing capacity.
The agency has asked state health authorities to provide readiness updates and immediately report suspected cases, high-risk exposures, unusual clusters of fever or significant preparedness gaps.
That raises a question that deserves more public attention:
How many states can demonstrate that these requirements are actually operational rather than simply documented in preparedness plans?
That is where the next phase of Nigeria’s Ebola preparedness will be tested.
AIRPORTS: THE FIRST LINE OF DEFENCE?
Nigeria’s international airports are particularly important because international travellers can potentially introduce infectious diseases into the country.
The NCDC has now tightened its health-declaration arrangements for travellers arriving from countries with active or relevant Ebola transmission.
Recent reports also indicate intensified surveillance and public-health sensitisation at the Nnamdi Azikiwe International Airport in Abuja.
But airport surveillance alone cannot provide a complete shield.
WHO has noted that formal border screening can be undermined by movement through informal crossing points.
Nigeria’s extensive land borders therefore remain part of the preparedness equation.
THE ONDO QUESTION
For Ondo State, the national warning deserves attention even though the state is not among the ten states classified by NCDC as high-risk.
Ondo shares important transport and commercial connections with neighbouring states and has a large network of public and private healthcare facilities.
The key issue is therefore not whether Ondo has been labelled a high-risk state.
It is whether the state can answer a more practical question:
If a patient with a recent international travel history arrives at a hospital in Akure, Owo, Ondo, Ikare or another community with fever and other compatible symptoms, will the health system recognise the possibility quickly enough — and know exactly what to do next?
That question extends beyond government hospitals.
Private hospitals, primary healthcare centres, laboratories, ambulance services and frontline health workers all form part of the chain of detection and response.
EBOLA IS NOT AN AIRBORNE DISEASE
The renewed alert should not become a source of unnecessary panic.
According to NCDC, Ebola is not transmitted through the air.
Transmission occurs principally through direct contact with blood or body fluids of a symptomatic or deceased infected person, contaminated materials or infected animals.
The incubation period can range from two to 21 days, making recent travel and exposure history important when assessing a suspected case.
NCDC says early symptoms may include fever, fatigue, muscle pain, headache, sore throat, vomiting, diarrhoea, abdominal pain and rash, among others.
The agency specifically warns health workers not to wait until bleeding occurs before considering Ebola in a patient with compatible symptoms and relevant travel or exposure history.
THE LESSON FROM 2014
Nigeria’s experience during the 2014 Ebola crisis demonstrated the value of rapid recognition, contact tracing, coordinated response and public-health leadership.
That experience is now being tested in a different environment and against a different Ebola virus.
The present outbreak also comes at a time when Nigeria’s health system is dealing with several other infectious-disease pressures.
The danger, therefore, is not simply the arrival of Ebola.
It is the possibility that a rare disease could initially be mistaken for something more familiar.
THE PIVOT INVESTIGATES
The most important questions now are not whether Nigerians should panic.
They should not.
The questions are whether Nigeria’s preparedness measures exist on the ground, whether isolation facilities are functional, whether frontline workers are adequately protected, whether laboratories and sample-transport systems can respond rapidly, and whether states can begin contact tracing immediately after a suspected case is identified.
For Ondo State specifically, The Pivot Online will be looking beyond official assurances to the practical readiness of the state’s health system.
Where is the designated holding facility?
How quickly can a suspected case be safely transferred?
Are frontline health workers trained and protected?
What happens to a suspected patient before laboratory confirmation?
These are not questions that should wait for Nigeria’s first case.
The window for preparedness is now.
And as the NCDC itself put it in its advisory, the critical period for action is before the first suspected case is reported.
The Pivot Online will continue to follow the Ebola situation, separating confirmed facts from rumours and examining Nigeria’s preparedness as the outbreak evolves.
