扩散-对流耦合作用下的登革热传播动力学模型
Dynamic Model of Dengue Fever Transmission under Coupled Diffusion-Advection Effects
摘要
Abstract
We established a Dengue fever transmission model that considered spatial heterogeneity and the advective effect of wind by using the theories of monotonic homogeneity and chain transitive sets.The results show that the basic reproduction number R0 determines the global threshold dynamics of the model:when R0≤1,the disease goes extinct;when R0＞1,the disease persists.Numerical analysis results show that R0 varies non-monotonically with the advection rate,and increasing the density of alternative hosts is helpful for disease prevention and control.关键词
