Abstract:The global stability of SIQR epidemiological model with continuous vaccinal immunity and bilinear incidence rates is discussed.The reproduction number for the model is found,which determines the existence of the infective disease.By means of linearization and Liapunov-Lasalle invaicant set theorem,the stable results of various equilibriums are obtained.The joint influences of quarantine period,infected period,and vaccinal immunity on the disease are exposed.
Keywords:epidemical model  basic reproduction number  equilibrium  global stability
