建立了一类具有媒体报道的双斑块迁移SIRS传染病模型
研究媒体报道作用下易感者与感染者迁移速率的改变对斑块内疾病状态的影响.首先
定义无迁移下的斑块基本再生数R1
R2
并推导系统的基本再生数R0
得到当R1<1且R2<1时
系统的无病平衡点是全局渐近稳定的
当R0> 1时
疾病是一致持续的.最后
通过数值模拟验证结果的有效性.
A type of two-patch dispersing SIRS epidemic model with media coverage is proposed to study the impact of induced migration rate of susceptible and infected persons by media coverage on the disease. Firstly
the number of non-migratory patch basic reproduction number R1
R2 is defined and the basic reproduction number R0of the disease is derived
by which we find that the disease-free equilibrium is globally asymptotically stable if R1< 1 and R2 < 1. However
the disease is uniform persistence if R0 > 1. Finally
some numerical examples are given to verify the validity of the results.
