摘要：
A simple SIRS epidemic model with nonlinear incidence is studied. The basic reproductive number is defined and the threshold of existence of multiple endemic equilibria is determined. It is found that Hopf bifurcation may happen for this model. The stable or unstable periodic solution is shown by numerical simulation.
