通勤对异质集合人群疾病持续性的影响

Impact of commuting on disease persistence in heterogeneous metapopulations

Ganna Rozhnova, Ana Nunes, Alan J. McKane

摘要:

我们使用一个随机集合种群模型来研究季节性和空间异质性对疾病持续性的综合影响。我们发现一个显着的效果增强持久性与强异质性,中间耦合强度和温和的季节性强迫。分析计算表明,这种影响是不相关的传染病爆发之间的相位滞后在不同的补丁,而是与吸引子的线性稳定性,描述了系统的稳定状态在大人口的限制。

英文摘要:

We use a stochastic metapopulation model to study the combined effects of seasonality and spatial heterogeneity on disease persistence. We find a pronounced effect of enhanced persistence associated with strong heterogeneity, intermediate coupling strength and moderate seasonal forcing. Analytic calculations show that this effect is not related with the phase lag between epidemic bursts in different patches, but rather with the linear stability properties of the attractor that describes the steady state of the system in the large population limit.
