Résumé

The work presented an age-structured deterministic model of a system of ordinary differential equations of diphtheria infection transmission dynamics. Optimal control theory was used to study the impact of personal protection, vaccination and treatment as effective control measures against the epidemics and established necessary conditions for the optimal control of the system. The application of time-dependent controls can reduce the total number of infected (symptomatic and asymptomatic) individuals in the population To determine the most influential parameters of the model that greatly influence the prevalence of diphtheria, sensitivity analysis was carried out on �
