What is diphtheria, the disease prompting Senegal to launch a vaccination campaign?

Diphtheria, an infectious disease caused by the bacterium Corynebacterium diphtheriae, was first confirmed in Senegal on August 1, 2026, with 34 cases reported, including six deaths. Symptoms include fever, sore throat, and respiratory difficulties, and the disease can be fatal without prompt treatment. In response to this resurgence, the Ministry of Health has launched a vaccination campaign to catch up on unvaccinated children and strengthen collective immunity.
