| Abstract: | In this paper, an epidemic model with constant contact rate is considered. Eigenspace method and Liap-nuov functional method are used to discuss the stabilities of positive constant stable soulation. A sufficient condition for the system to have a positive globally asymptotically stable solution is obtained. |
