The diphtheria outbreak in Nigeria has expanded to include Zamfara State, where health authorities have reported 39 deaths and 261 suspected cases across 10 Local Government Areas. Gusau has recorded the highest burden with 191 cases. Officials attribute the spread in Zamfara to missed vaccinations and immunization hesitancy, particularly among young children. In Plateau State, the outbreak—first noted in early August primarily in densely populated areas of Jos North—has reached 23 deaths and 148 suspected cases, though some local reports suggest the death toll may be as high as 27. In response to the spread in Jos North, Wase, Jos South, and Bassa Local Government Areas, the Plateau State Government has ordered the indefinite closure of all public and private primary and secondary schools, effective September 7, 2026. Health Commissioner Dr. Nicholas Baamlong expressed concern regarding the “national unavailability of diphtheria antitoxin,” noting that the federal government is working to procure the necessary treatment. Patients are currently receiving treatment at the Jos University Teaching Hospital and the Plateau Specialist Hospital, where isolation centers have been established. The state has alerted the Nigeria Centre for Disease Control and Prevention (NCDC) to assist with laboratory confirmation and sample transportation. In Katsina State, the outbreak spans 29 Local Government Areas, with Funtua recording the highest burden. Health officials attribute the spread to low vaccination rates and porous borders with the Niger Republic. In Kano State, authorities have confirmed two diphtheria-related deaths. The Nigerian Federal Government continues to manage the crisis through an emergency multi-agency task force focusing on intensified surveillance and immunization efforts. In Lagos State, Health Commissioner Prof. Akin Abayomi has denied reports of a widespread outbreak, stating that while the state has recorded 53 suspected cases and six laboratory-confirmed cases, all confirmed cases were appropriately managed.
