Background: Diphtheria is a re-emerging bacterial disease in developing countries with low vaccination coverage. Objectives: This is a descriptive cross-sectional study of diphtheria cases reported to the DRSP/Zinder from March 14, 2022 through June 26, 2023. Methods: It includes cases reported through epidemiological surveillance and data on patients hospitalized in the infectious and tropical diseases department of the Zinder National Hospital (SMIT). Results: A total of 32 patients were included in this study. The median age was 12 years [4-22 years]. Key symptoms included dysphagia and odynophagia (100 %), false membranes (84.4 %), fever (46.9 %), thrombocytopenia (39.3 %), cervical lymphadenopathy (37 %), respiratory distress (15.6 %), epistaxis (12.5 %), gingival bleeding (9.4 %), agitation (6.2 %) and paresis (3.1 %). Renal function was altered in 74 % of cases. Diagnostic confirmation was procured through culture on oropharyngeal swabs. Corynebacterium diphtheriae was isolated in 26.31 % (5/19) of cases. Patients were treated with macrolides and diphtheria antitoxin. The case fatality rate was 31.2 %. Poor prognostic factors included gingival bleeding (p = 0.0262), respiratory distress (p = 0.0374), and thrombocytopenia below 50,000 platelets/mm3 (p = 0.0020). Conclusion: Diphtheria is a deadly re-emerging disease. The fight against this condition necessitates improved vaccination coverage.
