摘要

In this paper,an SEIR model with nonlinear incidence rates are studied.The basic reproduction number R₀ characterizes the disease transmission dynamics: if R₀≤ 1,the disease-free equilibrium is globally asymptotically stable and the disease always dies out,if R₀> 1 then there is a unique endemic equilibrium which is globally asymptotically stable and the disease persists.
