Hopf bifurcation of nonlinear incidence rates SIR epidemiological models with stage structure
Here, the authors consider a nonlinear incidence rates SIR epidemiological model with stage structure. Different to bilinear rate models, there exist two positive equilibria and whether or not the disease will eventually die out may depend upon the initial values. Periodic solutions may appear by Hopf bifurcation.
