Containing new Ebola: The fault lines

17

In 2014, Nigeria was wracked with a devastating Ebola epidemic. The index case stole into Lagos on July 20, 2014. A Liberian man, Patrick Sawyer, had arrived in Lagos that day already infected with Ebola. He had travelled from Liberia, where an Ebola outbreak was already underway.

However, within just three months, the nightmare was over. Nigeria stunned the doubting world that had expected and even predicted the worst. It was incredulous. Our health experts rose stoutly to the occasion and within just three months, the epidemic was effectively contained.

The World Health Organization (WHO) officially declared Nigeria Ebola-free on October 20, the same year. A total of 20 cases and eight deaths, including that of brave frontline health worker, Dr. Ameyo Adadevoh, had, however, been recorded before the epidemic was wrestled down.

Now, exactly 12 years after, a fresh case has stealthily crept in, stirring another round of hysteria. And the fear is if the nation has the capacity to repeat the 2014 feat should the index case ravel out into an epidemic, going by the current realities in our fragile health sector. That is precisely the present danger.

The Federal Government through the Minister of Health and Social Welfare, Prof. Muhammad Ali Pate, officially announced the fresh case in Abuja last Tuesday, following laboratory confirmation of the infection.

According to the minister, the patient is a woman who recently arrived in Nigeria on an international flight from Uganda and was admitted to a private hospital in the FCT, where she received treatment for several days before the disease was confirmed.

He said: “A woman, who recently arrived in Nigeria on an international flight from Uganda, was admitted to a private hospital in the FCT, where she received treatment for several days before the diagnosis was confirmed.”

According to the Nigeria Centre for Disease Control and Prevention (NCDC), the woman presented with fever, diarrhoea, generalised body aches and sore throat. But no bleeding was reported.

The woman is currently in isolation and receiving medical care.

The Federal Ministry of Health and Social Welfare, NCDC and the FCT Health Services Secretariat are said to be working with other relevant authorities to contain the infection and prevent further transmission.

The number of identified contacts now being traced by public health workers has risen from 44 to 53. Contacts are still being widened to locate and monitor other potentially exposed persons, including healthcare workers, patients, caregivers and individuals who may have travelled with the patient.

The manner Nigeria successfully contained the 2014 Ebola outbreak is regarded as one of the most important public health achievements in Africa during the epidemic. Despite the virus entering Lagos, one of Africa’s most densely populated cities, the nation dealt it a lethal blow within approximately three months, preventing it from developing into a much larger national epidemic.

How was the feat achieved? The success resulted from rapid government action, effective contact tracing, isolation of infected patients, public education and the mobilisation of existing public health resources.

First, the blood sample of the index case, Patrick Sawyer, a Liberian, was promptly sent to the Lagos University Teaching Hospital (LUTH) for testing while he was being treated for what was suspected to be malaria at a private hospital in Lagos. His condition and travel history had raised concerns about Ebola. The infection was eventually confirmed. He died on July 25, 2014.

Second, one of the most canny decisions made by the government then was the rapid establishment of an Ebola Incident Management Centre. On July 23, 2014, the Federal Ministry of Health and Lagos State government activated the centre to coordinate the response.

Rather than allowing different agencies to operate independently, the centre brought together government officials, epidemiologists, medical personnel and international partners.

It coordinated activities such as identifying and monitoring exposed individuals; managing suspected and confirmed cases; organizing laboratory testing; deploying health workers and contact tracers; communicating with the public and coordinating assistance from international organisations.

The emergency centre built on systems and expertise developed through Nigeria’s existing polio eradication programme. This proved particularly valuable because the country already had personnel experienced in disease surveillance, field investigations and emergency coordination.

Third, contact tracing was arguably the most important operational measure in containing Ebola in 2014. Ebola is an insidious evil. It spreads primarily through direct contact with the blood or other bodily fluids of an infected person who is symptomatic, or with contaminated materials. Identifying exposed individuals before they spread the infection further is therefore essential.

Nigeria’s health experts identified people who had contact with Sawyer and subsequently with other infected persons.

The health authorities mobilised trained epidemiologists and more than 150 contact tracers in Lagos. They monitored identified contacts for symptoms, including fever, vomiting and diarrhoea and escalated suspected cases for medical assessment.

This intensive monitoring helped health authorities detect new cases and identify additional people who might have been exposed. By identifying and monitoring contacts systematically, the nation was able to interrupt chains of transmission before they expanded uncontrollably.

Fourth, another crucial measure was the prompt isolation of people suspected of having Ebola. Once a person was identified as a possible case, medical teams assessed the individual, arranged laboratory testing and isolated suspected cases to reduce the risk of transmission.

Dedicated Ebola treatment facilities were established, including facilities in Lagos and subsequently Port Harcourt, where another chain of transmission emerged.

Healthcare workers also implemented infection prevention and control procedures to reduce exposure while caring for patients.

The country also developed its capacity to diagnose Ebola locally. This helped authorities to confirm infections and rule out suspected cases, allowing them to concentrate resources on people who actually needed Ebola-specific care.

Fifth, people who had been exposed to Ebola were monitored for the virus’s incubation period, which can extend to 21 days. During this period, health workers checked contacts for symptoms and advised them on precautions to minimise the possibility of exposing others.

Most contacts were monitored at home, with instructions to avoid situations that could expose large numbers of people if symptoms developed. For some people whose exposure presented a particularly high risk, authorities used supervised quarantine arrangements.

Seventh, because the first case arrived by international air travel, authorities also strengthened surveillance at the ports of entry. Nigeria’s Port Health Services worked with airport authorities and airlines to identify potentially exposed passengers, investigate travel-related risks and communicate information to public health officials.

Screening measures were introduced at entry and exit points, including checks for symptoms and possible exposure to Ebola.

Authorities also used international health notification systems to alert relevant partners about potential exposure risks.

Eighth, public cooperation was another important component of Nigeria’s response. Health authorities conducted public education campaigns to explain Ebola transmission, symptoms and preventive measures.

Traditional and religious leaders as well as community representatives helped communicate health messages and encourage people to cooperate with surveillance teams. Public education was particularly important because fear, misinformation and rumours could have discouraged people from reporting symptoms or cooperating with contact tracers.

The government and its partners worked to ensure that the public understood the seriousness of the disease and the importance of early medical attention. WHO specifically recognised community engagement and public awareness as important contributors to Nigeria’s success.

Nineth, although Nigeria led the response, international assistance strengthened its effectiveness. Key partners included WHO, which provided technical expertise and supported outbreak investigation and coordination and Centers for Disease Control and Prevention (CDC),which supported epidemiological investigations, contact tracing, infection control and emergency response coordination.

Others were Médecins Sans Frontières (MSF), which contributed expertise and support for outbreak response and UNICEF, which sponsored public communication and community engagement.

The nation was able to combine this external assistance with its own public health personnel and existing disease-surveillance infrastructure. This partnership particularly strengthened the country’s capacity to respond quickly and systematically.

On October 20, 2014, WHO declared Nigeria free of Ebola transmission after the country completed the required 42-day period without new cases. This period represented two consecutive 21-day incubation periods.

Now, the big poser: Is it still possible for the nation to repeat the 2014 feat this time should the outbreak eventually develop into an epidemic, in view of the Nigeria’s parlous state of health? Of course, the health authorities have assured that the nation’s Ebola epidemic containment infrastructure remains intact and that they are battle-ready. 

The health minister specifically assured that the country possesses the experience and public health infrastructure needed to respond to the latest case, stressing that public cooperation would be critical to preventing further transmission.

The NCDC Director-General, Dr Jide Idris, like Pate, also assured Nigerians yesterday that the government, through the Federal Ministry of Health and Social Welfare, the NCDC, Federal Capital Territory health authorities and partners, is committed to containing the outbreak.

“I recognise the concern that the confirmation of Ebola may have caused among Nigerians. Ebola is a serious disease, and we are handling this situation with the urgency it deserves…

“We have a clear response plan, experienced personnel and established public health systems that we are deploying to prevent further transmission,” the NCDC boss enthused at a press briefing yesterday.

In spite of these assurances, however, public anxiety yet lingers because a lot has happened to Nigeria’s health sector during the intervening hiatus in between the last outbreak in 2014 and now. One of the main fault lines is the acute dearth of health workers and limited laboratory capacity in Nigeria. The situation is simply scary.

Even in 2014, Ebola response was slowed by a critical shortage of trained health workers willing to man isolation wards, driven by fear and inadequate infection prevention and control (IPC) training.

Nigeria’s bothersome health workforce crisis has further deteriorated 22 years after. The migration of medical professionals from Nigeria, locally dubbed the “Japa” phenomenon, has surged to unprecedented levels, with a staggering 43,221 health workers across all cadres relocating abroad between 2023 and 2024 alone.

This marks a shocking 200% increase in external migration compared to prior years, throwing Nigeria’s fragile healthcare ecosystem into its most severe workforce crisis in decades.

According to the official Nigeria Health Statistics Report released by the Federal Ministry of Health and Social Welfare, the mass relocation spans multiple core specialties.

About 4,193 medical practitioners left Nigeria in 2024 alone. This accelerates a long-term trend, pushing the total number of doctors who emigrated over the last few years past 16,000.

The nurses and midwives cadre is the hardest-hit, with more than 23,000 nurses migrating up to 2024. Over 11,300 laboratory scientists left the shores of Nigeria, with the vast majority migrating to Canada and the UAE. Pharmacists have also migrated in historically high volumes, seeking greener pastures in destinations like Canada, the UK and Australia.

Besides, the current outbreak, which started on May 16, this year, in the Democratic Republic of Congo(DRC) and the neighbouring Uganda, is caused by the Bundibugyo strain, for which no licensed vaccine currently exists. However, health authorities are still investigating to isolate the particular strain that has crept into Nigeria this time. This makes the current outbreak potentially dangerous and distinguishes it from the 2014–2016 West Africa crisis.

Then, only a few laboratories in Nigeria currently have the capacity to test for Ebola due to the high cost of setting up and maintaining such facilities. These laboratories include the National Reference Laboratory in Abuja, LUTH, the Nigerian Institute of Medical Research (NIMR), and some private laboratories.

Possible paucity of funds is another potential threat to containing the fresh outbreak. In 2014, slow flow of funds into the Emergency Operations Centre (EOC) initially threatened containment efforts, which were sustained largely by Lagos State and international partners.

In 2026, the fiscal environment is considerably more constrained. The suspension of the United States for International Development (USAID)  programme under the US foreign aid freeze, the drawdowns on the President’s Emergency Plan for AIDS Relief (PEPFAR) and Global Fund restructuring have collectively reduced Nigeria’s external health financing buffer.

Nigeria’s primary domestic health financing mechanism, the Basic Health Care Provision Fund (BHCPF), remains chronically underfunded. There is no dedicated emergency public health reserve. 

These are some of the extraneous hurdles that will come to play and which were hardly serious factors in 2014, as Nigerian health authorities— Federal Ministry of Health, the Presidential Task Force on Ebola, NDDC, FCT Health Services — supported by international partners like WHO and UNICEF, coalesce to frontally battle the fresh Ebola outbreak.

According to some health experts, it is a necessity for health authorities directly involved in the containment efforts to have an uninterrupted access to funds. The EOC must, therefore, be adequately funded and staffed as a continuous function, not as a reactive safehold.

This includes what they call a dedicated operating budget, pre-positioned supplies at state-level coordinators in all 21 identified high-risk states, and a clear command structure that bypasses political hierarchy in favour of technical leadership, as was effectively the case in 2014.

The Federal Government is also admonished to establish a dedicated Infectious Disease Emergency Reserve Fund, seeded through the Consolidated Revenue Fund. This should be supplemented by international commitments from WHO, the African Union’s Africa CDC, and the World Bank’s Pandemic Fund, to which Nigeria has access as a lower-middle-income country.

The government should also expand Ebola laboratory diagnostic capacity to such states as Kano, Borno, Adamawa, Taraba among others explicitly classified as high-risk. At a minimum, specimen referral networks with cold-chain transport protocols, experts recommend, should be established in these states.

What are the symptoms of Ebola? Its symptoms are said develop between two and 21 days after exposure to the virus.

Common symptoms include fever, vomiting, headache, diarrhoea, weakness and fatigue, pain, sore throat and bleeding in some cases.

Key advisory measures health authorities have devised to prevent infection include:

•Hand hygiene: Wash hands frequently with soap under clean running water, or use an alcohol-based hand sanitizer.

•Safe food and water: Drink only safe, treated or boiled water and ensure food is cooked thoroughly. Cover food storage properly to prevent contamination.

•Environmental cleanness: Keep surroundings clean, clear drainage, dispose of refuse properly and avoid open defecation.

•Vector and pest control: Prevent mosquito bites using insecticide-treated nets and control rodent exposure by sealing food items.

•Personal protection and isolation: Stay home when sick, avoid close contact with infected individuals and cover your mouth and nose when coughing or sneezing.
