Abstract EN
A delayed SEIRS epidemic model with pulse vaccination and nonlinear incidence rate is proposed.
We analyze the dynamical behaviors of this model and point out that there exists an infection-free periodic solution which is globally attractive if R1<1, R2>1, and the disease is permanent.
Our results indicate that a short period of pulse or a large pulse vaccination rate is the sufficient condition for the eradication of the disease.
The main feature of this paper is to introduce time delay and impulse into SEIRS model and give pulse vaccination strategies.
