中文摘要：

建立了一类有人口迁移的传染病模型,得到了该模型的基本再生数R0,证明了当R0〈1时无疾病平衡点是全局渐近稳定的,当R0〉1时存在地方病平衡点且该平衡点是全局渐近稳定的。

英文摘要：

In this paper, the basic reproduction number is obtained from the SIS epidemic model with population dispersal which is previously established. It is proved that the disease-free equilibrium is globally asymptotically stable if R0〈1 and endemic equilibrium exists and is globally asymptotically stable if .R0〉1.
