In this paper, we study a heroin epidemic model with distributed time delays. The basic reproduction number R 0 for the model is identified and the threshold property of R 0 is established. It is shown that drug-free equilibrium is globally asymptotically stable if R 0 < 1. When R 0 > 1, there is a
## Abstract We study the stability of a delay susceptibleβinfectiveβrecovered epidemic model with time delay. The model is formulated under the assumption that all individuals are susceptible, and we analyse the global stability __via__ two methodsβby Lyapunov functionals, andβin terms of the varia
