摘要
考虑媒体信息对HBV传染病的影响,构建了信息干预下的HBV传染病模型,研究了无病平衡点和地方病平衡点的存在性和稳定性,得到了无病平衡点和地方病平衡点的全局稳定性条件.根据相关结果发现适当地增加信息干预强度会减少HBV感染者数量,进而加快控制疾病的传播.
Abstract
Considering the influence of media information on HBV infectious disease,a model of HBV infectious disease under information intervention is constructed,the existence and stability of the disease-free equilibrium point and the endemic equilibrium point are further investigated,and the global stability conditions for the disease-free equilibrium and the endemic equilibrium are obtained.According to the relevant results,it is found that appropriately increasing the intensi-ty of information intervention reduces the number of HBV-infected people,which in turn accelerates the control of the spread of the disease.
