摘要: A heroin model with nonlinear incidence rate and age structure is investigated. The basic reproduction number determined whether or not a epidemic breaks out. By employing the Lyapunov functionals, drug-free equilibrium globally asymptotically stable if R0 ≤ 1; while drug spread also > 1. Our results imply that improving detected rates drawing up efficient prevention play more important role than increasing treatment for users.
