摘要
In this paper, we consider a stochastic epidemic model with relapse, cure and a nonlinear incidence rate function. Firstly, we show the existence and uniqueness of a global positive solution. Then, in terms of a stochastic threshold R-s(0). we prove the extinction of the disease when R-s(0) < 1. We also establish the persistence in mean of the epidemic in the case of R-s(0) > 1. Furthermore, we prove the existence of a stationary distribution and its asymptotic stability. Finally, we present numerical simulations for the stochastic model to support the theoretical results.
