Abstract: A SIRS infectious disease model with immigration,birth and death,vertical transmission,and isolation,is studied.According to the global asymptotical stability conditions of the disease-free equilibrium,the integrated strategy for controlling the disease—first isolating the infected individuals,then limiting the liquidity of the susceptible and controlling the vertical transmission,and at last making a tradeoff between annihilating the disease with no terms and the underlying expenses before taki...
