摘要:

COVID-19具有高度传染性,控制疫情暴发需要快速有效的应对措施。由于感染可能由症状前或无症状人群传播,在临床病例确诊之前,很可能已发生大量未被检测到的传播。因此,当疫情暴发时,需要预测哪些人群和地点面临更高的暴露风险。在本研究中,我们评估了聚合人类移动数据在估计传播风险地理分布方面的实用性。我们提出了一种简单的方法,利用近实时的人口移动数据生成空间传播风险评估。我们针对澳大利亚三个有详细记录的COVID-19疫情暴发情景验证了我们的估计结果。其中两个是明确的传播集群,一个是社区传播情景。我们的结果表明,移动数据可以很好地预测来自传播中心的暴露风险地理模式,特别是在涉及工作场所或其他与习惯性出行模式相关的环境中。对于社区传播情景,我们的结果表明,当病例数较低且空间聚集时,移动数据对风险预测的增值最大。我们的方法可以帮助卫生系统分配检测资源,并可能指导实施针对特定地理区域的流动和社交互动限制措施。

英文摘要:

COVID-19 is highly transmissible and containing outbreaks requires a rapid and effective response. Because infection may be spread by people who are pre-symptomatic or asymptomatic, substantial undetected transmission is likely to occur before clinical cases are diagnosed. Thus, when outbreaks occur there is a need to anticipate which populations and locations are at heightened risk of exposure. In this work, we evaluate the utility of aggregate human mobility data for estimating the geographic distribution of transmission risk. We present a simple procedure for producing spatial transmission risk assessments from near-real-time population mobility data. We validate our estimates against three well-documented COVID-19 outbreak scenarios in Australia. Two of these were well-defined transmission clusters and one was a community transmission scenario. Our results indicate that mobility data can be a good predictor of geographic patterns of exposure risk from transmission centres, particularly in scenarios involving workplaces or other environments associated with habitual travel patterns. For community transmission scenarios, our results demonstrate that mobility data adds the most value to risk predictions when case counts are low and spatially clustered. Our method could assist health systems in the allocation of testing resources, and potentially guide the implementation of geographically-targeted restrictions on movement and social interaction.
