研究了一类具有双线性发生率和Neumann边界条件的非局部(卷积)扩散的SIS传染病模型。首先,我们建立的存在性和唯一性的稳定的解决方案,通过减少系统到一个单一的方程。然后,我们研究了大的和小的扩散率的地方病稳定状态的渐近轮廓,以说明传染病的持久性或灭绝。地方病稳态的缺乏规律性,使得获得地方病稳态序列的极限函数更加困难。我们还观察到当受感染个体的扩散率趋于零时发生的集中现象。我们的分析结果表明,除非总人口规模相对较小,否则限制易感个体的流动并不能有效地消除传染病。
This paper is concerned with a nonlocal (convolution) dispersal susceptible-infected-susceptible (SIS) epidemic model with bilinear incidence and Neumann boundary conditions. First we establish the existence and uniqueness of stationary solutions by reducing the system to a single equation. Then we study the asymptotic profiles of the endemic steady states for large and small diffusion rates to illustrate the persistence or extinction of the infectious disease. The lack of regularity of the endemic steady state makes it more difficult to obtain the limit function of the sequence of endemic steady states. We also observe the concentration phenomenon which occurs when the diffusion rate of the infected individuals tends to zero. Our analytical results demonstrate that limiting the movement of susceptible individuals is not effective in eliminating the infectious disease unless the total population size is relatively small.
