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