Abstract：In this paper， adult infected individuals are divided into two stages： mild infected individuals and severe infected individuals， and a saturated form of input function is considered to establish a type of epidemic disease model with stage structure. The existence and stability of the equilibrium point of the system are analyzed by Hurwitz criterion and constructing Lyapunov function. It is found that when certain conditions are satisfied， Hopf bifurcation will occur in the system.
