动物运动影响人类和野生动物疾病的传播，人们对了解迁徙、生物入侵和其他野生动物运动在空间感染动态中的作用非常感兴趣。然而，在宿主运动的短暂阶段，作用于感染的过程的影响还知之甚少。我们提出了一个概念框架，该框架明确地考虑了宿主运动瞬时阶段的感染动态，以更好地预测通过空间宿主网络传播的感染。考虑到主机的瞬时移动，可以捕获主机在不同位置之间移动时发生的关键过程，这些过程共同决定了主机通过网络传播感染的速度。我们回顾了关于宿主运动和感染传播的理论和实证研究，强调了影响宿主感染状态的多种因素。然后，我们概述了宿主、寄生虫和影响这些动态的环境的特征。最近的技术进步为疾病生态学家提供了前所未有的能力来跟踪生物体的精细运动。这些与在宿主运动期间驱动感染动态的因素的实验测试相结合，可以为基于组成生物过程的感染传播模型提供信息。
Animal movement impacts the spread of human and wildlife diseases, and there is significant interest in understanding the role of migrations, biological invasions and other wildlife movements in spatial infection dynamics. However, the influence of processes acting on infections during transient phases of host movement is poorly understood. We propose a conceptual framework that explicitly considers infection dynamics during transient phases of host movement to better predict infection spread through spatial host networks. Accounting for host transient movement captures key processes that occur while hosts move between locations, which together determine the rate at which hosts spread infections through networks. We review theoretical and empirical studies of host movement and infection spread, highlighting the multiple factors that impact the infection status of hosts. We then outline characteristics of hosts, parasites and the environment that influence these dynamics. Recent technological advances provide disease ecologists unprecedented ability to track the fine-scale movement of organisms. These, in conjunction with experimental testing of the factors driving infection dynamics during host movement, can inform models of infection spread based on constituent biological processes.
