| Abstract: | In this paper, an SIS epidemic model with logistic dynamics that consists immature and mature stage is studied. If the system has no positive equilibrium, the boundary equilibrium is asymptotically global stable; If the system has positive equilibrium, it is asymptotically global stable. Therefore, the threshold is found. |

| Keywords: | stage structure asymptotically stable SIS model threshold |
