On Dynamic Analysis of a Viral Infection Model with Nonlinear Effective Contact rate
-
摘要: 构建并分析了一类具有非线性有效接触率的病毒感染模型的全局动力学性态,结果发现:当病毒基本再生数小于1时,病毒绝灭平衡点全局渐近稳定;反之,模型的正平衡点全局渐近稳定。Abstract: In this paper ,a viral infection model with nonlinear effective contact rate has been proposed and its global dynamic behavior analyzed .The results show that the virus‐free equilibrium is globally asymp‐totically stable if the basic reproduction number of virus is less than one .Otherwise ,the positive equilibri‐um is globally asymptotically stable .
