摘要
研究了一类具有Logistic死亡且成年染病的SIS阶段结构模型的渐近形态,讨论了无病平衡点和地方病平衡点的存在性及局部和全局稳定性,得出了疾病消除和成为地方病的阈值.
In this paper,the asymptotic behavior of a structured SIS epidemic model with Logistic death rate is studied. Sufficient conditions for the existence and locally and globally asymptotic stability of the disease free equilibrium and endemic equilibrium are obtained.The threshold is found which the epidemic will become endemic or die out.
