SEI EPIDEMIC MODELS WITH NON-LINEAR INCIDENCE RATE AND UNIFORM REPRODUCTION
2010
In this paper, a general SEI epidemic model is considered with nonlinear incidence rate and uniform reproduction rate more general than those in the literature. Disease-free and endemic points are discussed with their stabilities. Hopf bifurcation and periodic solution are studied. Numerical discussion is given to show the effects of changing parameters of the system.
