Asymptotical Stability of an SIQS Epidemic Model with Age Dependence and Generally Nonlinear Contact Rate

Article Preview

Abstract:

In this paper, an SIQS epidemic model with infection age and generally nonlinear contract rate is formulated. The existence and asymptotic stability of equilibrium are respectively discussed, and a general condition is obtained under which the endemic equilibrium is exponentially asymptotically stable.
