| Abstract: | According to the propagation of the epidemic,a SEIRS epidemic system with time delays and nonlinear incidence rate was established. The existence and global attractivity of the infection-free periodic solution were proved.In the end,the sufficient conditions for which the system is persist were obtained. |

| Keywords: | time delay global attractive impulsive differential system permanence |
