Abstract

In this paper, we investigate the dynamics of a SIRVS epidemic model with pulse vaccination strategy and saturation incidence. We show that the disease is eradicated when the basic reproduction number is less than unity, and the disease is permanent when the basic reproduction number is greater than unity. Finally, by means of numerical simulation, we obtain the parameters reach some critical value, and the disease will go to extinction.
