具有交叉感染的2种菌株对逼近模型分析
Analysis of pair approximation model of two strains with the cross infection
摘要
Abstract
To study the dynamics of pair approximation SIS model with general comtact rate and treatment.The pair approximation SIS model with a cross infection two strains are established in this paper in view of the two strains could live independently.We got a 12d system using the node status correlation coefficient based on the binomial distribution.In addition,we concluded that the local stability of the disease-free equilibrium by calauating the model of the basic reproductive number,and then,the unstable threshold of disease-free equilibrium is found.Finally,model of the disease-free equilibrium existenced unconditionally and it namely is not stable through theoretical analysis and numerical simulation.The conditions of two strains exist independently and the common survival are studied in this paper,and then,we concluded that two strains can live independently,and also be infected with each other.The high dimensionality (12) system is studied.The approximation model not only simulate the spread of disease mechanism but also capture the spread of disease in populations of network structure.So it has a certain value that applying the approximation model to many strains of the spread of disease.关键词
