摘要
讨论了具有双时滞的SIS传染病模型.研究了一个边界平衡点的全局稳定性和正平衡点的局部稳定性,得到了传染病最终消失和成为地方病的阈值.
This paper considered a SIS epidemic model that incorporates delay.The local stability of positive equilibrium and global stability of border equilibrium are proved.The endemic threshold is found which the epidemic will endemic or die out.
