Crisis Deepens: Diphtheria Outbreak Grips Nigerian Regions

Nigeria is grappling with widespread diphtheria outbreaks across several states, particularly Plateau, Katsina, and Kano, where authorities are struggling to contain the highly infectious disease that has claimed numerous lives and sickened many. The outbreaks highlight critical challenges in public health response, including shortages of essential medical supplies and late patient presentations.

In Plateau State, Jos North Local Government Area alone has recorded at least 23 deaths and 143 suspected cases. The state Commissioner for Health, Dr. Nicholas Baamlong, disclosed that most casualties occurred in the last three weeks, with nine patients currently receiving treatment at isolation centers in Jos University Teaching Hospital (JUTH) and Plateau Specialist Hospital. Major obstacles include the scarcity of diphtheria antitoxin and specialized containers for sample collection and transportation, hindering accurate diagnosis. The Nigeria Centre for Disease Control and Prevention (NCDC) has been informed and support is expected. Awareness campaigns, leveraging traditional rulers, are underway to educate communities on symptoms, transmission, and prevention.

Katsina State faces a severe outbreak, with diphtheria spreading to 30 of its 34 Local Government Areas. While the state government reported 31 confirmed cases since a recent surge three weeks prior, officials at the Federal Teaching Hospital Katsina (FTHKT) noted approximately 150 admissions and 29 deaths within the same period, indicating a discrepancy in reported figures. The state has established three additional isolation centers in Daura, Funtua, and Katsina, and procured vaccines and medical supplies in collaboration with partners. Despite claims of declining cases since 2023, there has been an increase in admissions in 2026, with 1,837 suspected cases recorded this year. A nine-year-old girl, Hafsat, recently discharged, returned to FTHKT with severe complications, highlighting the disease's long-term effects. This underscores the urgency of early medical attention to prevent complications affecting vital organs like the heart and kidneys.

Kano State has received 650,000 doses of diphtheria vaccines from the Federal Government, but the state's Director General of the KNCDC, Prof. Muhammad Adamu Abbas, emphasized that nine million doses are needed for effective containment across all 44 LGAs. Abbas has engaged traditional leaders to mobilize communities for vaccination and containment efforts. Active case searches are being conducted in affected areas, particularly Rano LGA, to strengthen surveillance and improve reporting. There has been controversy over casualty figures, with the KNCDC dismissing unverified claims of over 50 child deaths in Rano, clarifying that only two deaths were recorded there in 2026, with a cumulative 29 deaths statewide since July 2023. A Special Committee on Diphtheria Outbreak Response has been inaugurated to coordinate interventions and ensure transparency.

Nationally, the NCDC has recorded over 10,000 confirmed diphtheria cases this year. While the proportion of confirmed cases resulting in death has declined compared to last year, gaps in vaccination coverage, particularly among children, remain a major concern. Insecurity, hard-to-reach communities, displacement, and population movement further complicate efforts to reach all eligible children with vaccinations. Dr. Jide Idris, NCDC Director General, reiterated that diphtheria is vaccine-preventable and urged parents to ensure children are fully vaccinated, emphasizing that vaccines are available free of charge. Healthcare workers are advised to maintain a high index of suspicion and promptly report and manage suspected cases.

Diphtheria is a serious, vaccine-preventable bacterial infection caused by toxin-producing strains of Corynebacterium diphtheriae, as explained by Dr. Aminu Mato Jitandutse of AKTH. It primarily affects the nose and throat, spreading through respiratory droplets and close contact. The bacterial toxin can damage the heart, nerves, and other organs, leading to complications like myocarditis, nerve damage, kidney problems, or even death. Common symptoms include sore throat, painful swallowing, low-grade fever, swollen neck glands (bull neck in severe cases), and a thick grey or whitish membrane over the tonsils or throat. Professor Sabo Ahmed of the University of Jos also highlighted the respiratory system's involvement and emphasized that early diagnosis and immediate treatment are crucial to prevent complications and deaths. Prevention relies on routine childhood vaccination, booster doses, prompt medical evaluation of suspected cases, isolation of confirmed cases, preventive antibiotics for close contacts, and basic hygiene practices like handwashing and avoiding sharing personal items. Diphtheria is a medical emergency, and urgent assessment at a health facility is advised for anyone presenting with a sore throat accompanied by a grey throat membrane, neck swelling, or breathing difficulty.
