摘要
考虑疾病在传播过程中病毒产生变异的影响,建立了具有病毒变异情况的SEIR传染病模型,借助Liapunov函数,分析了无病平衡点和地方病平衡点的全局稳定性.并通过数值模拟分析了模型中的参数对疾病传播的影响.
In this paper, we consider the disease viruses mutate in the process of transmission, and the virus mutate situation of SEIR epidemic model is established. stability of equilibrium and the disease-free equilibrium. parameters for disease transmission of influence. With the help of function Liapunov, we analysise the global Numerical simulations are carried out to illustrate the main parameters for disease transmission of influence.
