摘要:

全球流动性数据是用于预测传染病行为的空间流行病学模型的核心,但这种丰富的人类流动性数据在很大程度上被利用病毒遗传数据重建病原体演化动力学所忽视。虽然病毒进化的随机模型可能会被这些数据所告知,但一个主要的挑战在于决定哪些流动性过程是关键的,以及它们在多大程度上有助于塑造病原体多样性的同期分布。在这里,我们开发了一个框架,整合预测的病毒扩散与地理推断和估计人类流感H3N2迁移的历史,同时测试和量化的因素,它的基础上,我们提供的证据,航空旅行管理的全球动态的人类流感,而其他过程中的作用在一个更本地的规模。

英文摘要:

Global mobility flow data are at the heart of spatial epidemiological models used to predict infectious disease behavior but this wealth of data on human mobility has been largely neglected by reconstructions of pathogen evolutionary dynamics using viral genetic data. Although stochastic models of viral evolution may potentially be informed by such data, a major challenge lies in deciding which mobility processes are critical and to what extent they contribute to shaping contemporaneous distributions of pathogen diversity. Here, we develop a framework to integrate predictors of viral diffusion with phylogeographic inference and estimate human influenza H3N2 migration history while simultaneously testing and quantifying the factors that underly it. We provide evidence for air travel governing the global dynamics of human influenza whereas other processes act at a more local scale.
