人类运动网络中的空间超传播者和超传播者

Spatial super-spreaders and super-susceptibles in human movement networks

Wei Chien Benny Chin, Roland Bouffanais

摘要:

随着全球各地开始解除封锁和居家令,各国政府正在努力制定有效和切实可行的指导方针,以重新开放经济。在人口密集的城市环境中,随着人们重返工作岗位,公共交通恢复满负荷运转,执行严格的社交距离措施将极具挑战性,甚至是不可能的。因此,各国政府正在密切关注可能成为下一个疾病传播集群的特定地点。事实上,某些地方,就像某些人一样,可以成为“超级传播者”。“与郊区拥挤的公共汽车换乘站相比,中央商务区繁忙的训练站是否更容易受到影响?在这里,我们提出了一个定量和系统的框架,以确定空间的超级传播者和新的概念的超级传播者,即分别,最有可能有助于疾病传播或感染it.Our建议的数据分析框架的人是基于新加坡公共交通的每日汇总的乘客量数据。通过构建有向和加权的人类运动网络,并将人流强度与两个邻域多样性度量相结合,我们能够确定超级传播者和超级易感位置。我们的研究结果表明,大多数超级传播者也是超级敏感者,而且与直觉相反,繁忙的外围公交换乘站比拥挤的中心训练站更危险。我们的分析是基于新加坡的数据,但可以很容易地适应和扩展到任何其他主要城市中心。因此,它可以作为一个有用的框架,为城市规划和流行病防备工作制定有针对性和具有成本效益的预防措施。

英文摘要:

As lockdowns and stay-at-home orders start to be lifted across the globe, governments are struggling to establish effective and practical guidelines to reopen their economies. In dense urban environments with people returning to work and public transportation resuming full capacity, enforcing strict social distancing measures will be extremely challenging, if not practically impossible. Governments are thus paying close attention to particular locations that may become the next cluster of disease spreading. Indeed, certain places, like some people, can be "super-spreaders." Is a bustling train station in a central business district more or less susceptible and vulnerable as compared to teeming bus interchanges in the suburbs? Here, we propose a quantitative and systematic framework to identify spatial super-spreaders and the novel concept of super-susceptibles, i.e. respectively, places most likely to contribute to disease spread or to people contracting it. Our proposed data-analytic framework is based on the daily-aggregated ridership data of public transport in Singapore. By constructing the directed and weighted human movement networks and integrating human flow intensity with two neighborhood diversity metrics, we are able to pinpoint super-spreader and super-susceptible locations. Our results reveal that most super-spreaders are also super-susceptibles and that counterintuitively, busy peripheral bus interchanges are riskier places than crowded central train stations. Our analysis is based on data from Singapore, but can be readily adapted and extended for any other major urban center. It therefore serves as a useful framework for devising targeted and cost-effective preventive measures for urban planning and epidemiological preparedness.
