摘要
媒体报道对传染病的感染率有着重要的影响,为探究这种影响建立了一类受媒体报道影响的SEIS模型。定义了模型的基本再生数R_0。当R_0> 1时,得到了地方疾病平衡点是全局渐近稳定的条件。最后得出结论:媒体报道对传染病的影响决定于报道信息的有效传播率。
Media has an important influence on the incidence rate of infectious disease.A SEIS epidemic model is formulated and analyzed to describe the saturated media/psychology impact.And the basic reproductive number is defined in the paper.Conditions of global asymptotic stability of the positive equilibrium are obtained when R 0>1.In the end,the conclusion that media/psychological impact depends on information′s effective transmission rates is drawn.
