A Delayed Epidemic Model with Pulse Vaccination

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 re...
