In early September 2026, Senegal launched a catch-up vaccination campaign following a diphtheria outbreak first detected on August 1. The outbreak resulted in 34 confirmed cases and six deaths, with the Kédougou region being the most heavily affected, accounting for 23 cases. Other cases were reported in Dakar, Thiès, Louga, Diourbel, and Kaolack.

Health authorities implemented a response strategy including the treatment of infected individuals, systematic investigations, contact tracing, and enhanced epidemiological surveillance. The vaccination campaign specifically targets children who have not received all recommended doses to strengthen collective immunity.
