Considering the effect of isolation and vaccination on control of disease,a SEIQR epidemic modelwith saturated incidence and time delay is established. Then,the existence condition of the disease-free equilibriumand endemic equilibrium and the permanence of model are obtained. The global stability of the disease-freeequilibrium and endemic equilibrium are proved by constructing an appropriate Liapunov function,numericalsimulations are presented to verify the properties of the models dynamics.
