Global Analysis of an SEIR Epidemic with Nonlinear Incidence rate

摘要：

An SEIR epidemic model with nonlinear incidence rate βSψ(I) was established,and it was obtained that the basic reproduction number determining whether the disease becomes endemic disease,then the global stability of the disease-free and endemic equilibria was proved by Lassalles Invariant Principle.
