The authors study a SIS epidemic model with stage structure and time delay. Sufficient conditions are derived for the stability of a disease-free equilibrium and an endemic equilibrium. The study shows that the stage structure has no effect on the epidemic model while the Hopf bifurcation occurs as the time delay increases. Some interesting numerical simulations are presented to support the analytical analyses.
