description | In this paper, we investigated a new heroin–cocaine epidemic model which incorporates spatial heterogeneity and nonlinear incidence rate. The main project of this paper is to explore the threshold dynamics in terms of the basic reproduction number [Formula: see text], which was defined by applying the next-generation operator. The threshold type results shown that if [Formula: see text], then the drug-free steady state is globally asymptotically stable. If [Formula: see text], then heroin–cocaine spread is uniformly persistent. Furthermore, the globally asymptotic stability of the drug-free steady state has been established for the critical case of [Formula: see text] by analysing the local asymptotic stability and global attractivity. |
