Northern Nigeria’s struggle to keep millions of children in classrooms is facing a renewed threat from a vaccine-preventable disease, forcing state governments into a delicate balancing act between public health and learning continuity.
The dilemma is particularly acute in a region already carrying a disproportionate burden of Nigeria’s out-of-school children, where years of insecurity, poverty, and weak access to basic education have kept many away from school. Now, a diphtheria outbreak is creating a fresh layer of uncertainty, highlighted by rapid policy shifts at the subnational level.
Plateau State, which initially shut all public and private primary and secondary schools indefinitely on September 7 following a sharp rise in infections, has swiftly reversed course, announcing a September 14 reopening. Other heavily affected states, including Kano, Kaduna, Katsina, Taraba, and Gombe, opted to keep schools open from the start despite mounting infections.
The divergence exposes a deeper systemic gap in the country’s public health response: there is no uniform threshold for when an outbreak warrants disrupting education, nor is there sufficient state-level data to help parents assess the risk to their children.
Families face an impossible dilemma. Keeping children in school protects their education but could increase exposure to a highly contagious disease if vaccination and infection-control measures are inadequate. Closing schools, even temporarily, pushes children back into communities where supervision and learning are not guaranteed.
The consequences are not theoretical. Nigeria has recorded more than 10,000 confirmed diphtheria cases in 2026, according to figures from the Nigeria Centre for Disease Control and Prevention (NCDC). The agency reported that 68 percent of confirmed cases involve unvaccinated individuals, with eight northern states accounting for 98 percent of the burden. Recent weekly figures from late August showed 69 suspected cases, 48 confirmed cases, and four deaths in a single week.
Plateau’s Policy Pivot
Plateau provides the clearest illustration of the tension between managing a health emergency and preventing an education crisis. The state’s suspected diphtheria cases climbed to 303, with deaths rising to 27, prompting the government to order an indefinite shutdown. Joyce Ramnap, Plateau State commissioner for information and communication, had initially directed all schools to remain safely shut to contain the spread.
However, the rapid decision to reopen by September 14 underscores the severe socio-economic pressures of keeping children at home. Many families in the region depend on informal daily wages and cannot easily provide alternative learning arrangements or daytime supervision. Furthermore, prolonged closures risk widening existing education inequalities, as poorer children lose learning time while wealthier peers pivot to private tutoring or digital platforms. The economic effects also immediately impact teachers, transport operators, food vendors, and security guards whose daily incomes rely on school activity.
Kano chooses continuity
Kano, sitting at the epicenter of Nigeria’s diphtheria burden, chose a different path entirely. The state government ruled out closures from the onset, arguing the situation did not warrant keeping children out of classrooms.
Nabilus Kofar-Naisa, spokesperson for the Kano State Ministry of Health, confirmed schools would operate as scheduled despite Plateau’s initial decision. He urged parents to monitor children for symptoms, keep sick pupils at home, and promptly seek medical attention.
While this policy protects the academic calendar, it places a heavy burden on the health and education infrastructure. Operating schools safely during an outbreak requires active surveillance, trained teachers, rapid referral systems, and aggressive vaccination of eligible children. Without these safeguards, keeping schools open risks turning classrooms into transmission hubs.
Eight states carry 98% of the burden
The geographic concentration of the disease makes the education question even more urgent. NCDC data confirms that Kano, Kaduna, Katsina, Borno, Bauchi, Plateau, Sokoto, and Zamfara account for 98 percent of confirmed cases. These are the exact states responsible for educating some of the largest concentrations of vulnerable children in the country.
The underlying vulnerability remains the vaccination gap. With 68 percent of confirmed cases involving unvaccinated individuals, and another 28 percent possessing an unknown vaccination status, school closures are merely a temporary buffer. As students in Plateau return to their desks and schools in Kano remain open, classrooms will continue to carry severe risks until aggressive, localized vaccination campaigns close the region’s immunity gap.
Katsina faces a second infectious-disease concern
Katsina illustrates another dimension of the challenge. As schools reopened for the 2026/2027 academic session, the state Ministry of Basic and Secondary Education warned parents about an outbreak of conjunctivitis, commonly known as Apollo. The state is facing a double whammy of apollo while heavily intensifying diphtheria vaccinations in affected areas.
Sani Danjuma, public relations officer of the ministry, urged parents to keep children showing symptoms at home and obtain medical attention before returning them to school. The ministry did not disclose the number of cases or the specific areas affected.
Although conjunctivitis is different from diphtheria, the warning reinforces the vulnerability of schools to communicable diseases when thousands of pupils return simultaneously to classrooms, dormitories and other shared spaces. The lesson for education authorities is that school health cannot be treated as an issue to be addressed only when an outbreak becomes severe.
Benue adopts surveillance before confirmation
In Benue, authorities say there is no confirmed diphtheria outbreak but have intensified surveillance.
Asema Msuega, state epidemiologist, told BusinessDay that the Disease Surveillance and Notification Officers had increased monitoring across the state’s 23 local government areas and the state capital. He said suspected samples had been sent for laboratory diagnosis and that results were still being awaited.
Msuega said the Ministry of Health remained on alert and would communicate the findings once laboratory results were available. Benue’s approach demonstrates the importance of acting before an outbreak becomes widespread.
The absence of confirmed cases should not translate into the absence of preparedness.
The bigger casualty is learning outcomes
The immediate victims of the outbreak are those who become sick and those who lose their lives. But there is a second, less visible casualty – learning. Every week that a child misses school can compound existing learning deficits, particularly for pupils who are already behind their peers. This is why the debate should not be reduced to whether governments should close schools. The more important question is whether authorities have done enough to make it possible for schools to remain open safely.
A situation where schools remain open, governments must demonstrate that vaccination, surveillance and case-management systems are sufficiently strong to protect pupils and teachers.
The NCDC itself identifies inadequate vaccination as a major factor behind diphtheria outbreaks. The agency says diphtheria is primarily controlled through high population immunity achieved by high vaccination coverage. That makes vaccination the most important long-term intervention.
What needs to change
The first priority should be an aggressive vaccination catch-up campaign targeting children who missed routine immunisation, particularly in the eight states accounting for the overwhelming majority of confirmed cases. Rather than waiting for children to present at health facilities, vaccination teams should work with schools, primary healthcare centres, traditional institutions, religious leaders and community organisations to identify children who have missed doses.
Schools in high-burden areas need active disease surveillance. Teachers and school health personnel should know what symptoms to look for, where suspected cases should be referred and when pupils should be temporarily kept away from school. States need stronger laboratory and case-management capacity. Early diagnosis is critical because delays can allow transmission to continue while infected children move between homes, classrooms and communities.
Suspected cases should have rapid access to appropriate treatment, while close contacts are identified and managed according to public-health protocols. Similarly, governments need to publish clearer and more frequent data.
Parents should not have to rely on rumours or social media to determine whether an outbreak is spreading around their children’s schools. States should provide regular information on suspected and confirmed cases, affected local government areas, vaccination coverage, school interventions and the criteria being used to decide whether schools remain open.
In addition, school closure decisions should be risk-based rather than uniform. Where transmission is intense, temporary closure may be justified. But closures should be accompanied by vaccination drives, surveillance and a clear reopening plan. Otherwise, children may simply lose education time without the underlying risk being addressed.
Finally, northern states need to treat health as part of their education strategy rather than an issue belonging exclusively to the health ministries. A school cannot function effectively if children are repeatedly absent because of preventable diseases. Neither can an education recovery programme succeed if health emergencies continually interrupt the academic calendar.
A warning beyond diphtheria
The diphtheria outbreak is therefore more than a public-health emergency. It is a test of northern Nigeria’s ability to protect its fragile education gains. The region cannot afford a cycle in which insecurity keeps children away from school, disease closes classrooms, and poverty prevents them from returning. Nigeria has already seen how infectious diseases can expose weaknesses in vaccination, surveillance and primary healthcare. The current diphtheria outbreak offers an opportunity to fix those weaknesses before they become another permanent barrier to education.
The immediate objective should not simply be to decide whether children should be in school or at home.
It should be to create conditions in which they can safely remain in school. For a region with millions of children still outside the classroom, that distinction could determine whether the current outbreak becomes a temporary health emergency – or another setback in the long struggle to get northern Nigeria’s children educated.
