Senegal is currently facing a resurgence of diphtheria, with 114 confirmed cases and 11 deaths reported as of September 20, 2026, according to the Ministry of Health.
The outbreak began in late July 2026 in Kédougou, eastern Senegal, where several children under five died showing symptoms consistent with respiratory diphtheria. The Institut Pasteur in Dakar confirmed the diagnosis on August 1.
The epidemic has spread rapidly, affecting 31 health districts across 12 of the country’s 14 regions, including Kédougou, Louga, Dakar, Diourbel, and Thiès. The Ministry of Health’s response coordination team reported a lethality rate of approximately 10%, meaning one death per ten infected individuals.
Diphtheria is caused by the bacterium Corynebacterium diphtheriae, which produces a toxin that damages throat tissues and can affect the heart and nerves. Early symptoms resemble a common sore throat but can quickly worsen, forming a characteristic membrane in the throat that can obstruct breathing.
Despite the availability of effective vaccines and treatments, the disease remains dangerous, especially to young children. This outbreak echoes similar epidemics in neighboring Guinea since 2023, underscoring the need for vigilant public health measures and vaccination campaigns in West Africa.
