一类带有非线性传染率的SIRS传染病模型
摘要
建立了一类带有非线性传染率的SIRS传染病模型
得到了地方病平衡点存在的阈值.当该阈值不大于1时
无病平衡点是全局渐近稳定的.当该阈值大于1时
无病平衡点是不稳定的
地方病平衡点是全局渐近稳定的.
Abstract
A SIRS epidemic model with a nonlinear incidence rate is established. The threshold of existence of endemic equilibrium is found. The disease-free equilibrium is globally asymptotically stable when the threshold is not greater than one; the disease-free equilibrium is unstable
and the endemic equilibrium is globally asymptotically stable when the threshold is not greater than one.
