✦ Synopsis

a b s t r a c t

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.

A SIS epidemic model incorporating media coverage is presented in this paper. The dynamics of this disease model under constant and pulse vaccination are analyzed. First, stability analysis of the model with constant vaccination shows that the disease free equilibrium is globally asymptotically stab
