Open publisher page 1 citations

Abstract

Assuming that latent and infected individuals have infectivity and infected individuals have lifelong immunity after recovery of the disease.An infectious disease models was built with a class of nonlinear infectious rate(γaE/(1+bEn)+λaI/(1+bIn)),the basic reproduction number was got that if the disease will become endemic diseases,as well as discussion on the global stability of the disease-free equilibrium and the endemic equilibrium.
