Abstract:In this paper, a discrete SIS epidemic model with saturation incidence rate is investigated;the basic reproduction number of the model is derived.By means of linearization and LaSalle-Lyapunov theory,it is proved that if the basic reproduction number R0 is less than unity, the disease-free equilibrium is globally asymptotically stable;through iteration scheme,it is derived if the basic reproduction number R0 is greater than unity,the endemic equilibrium is globally asymptotically stable.
Keywords:, discrete epidemic model,saturation incidence rate,the basic reproduction number,iteration
