Considering the infection of the nonlinear contact rate and latent period,a class of SEIR epidemicmodel is studied. Using the theory of Lasalle and autonomous convergence theorem,the global stability of the disease一free equilibrium and the endemic equilibriumare proved.talne(1,and the accuracy of the model’s conclusionproved byThe sufficient conditions of bifurcation are ob-numerical simulation.
