异构干预降低真实移动数据仿真中COVID-19的传播

Heterogeneous Interventions Reduce the Spread of COVID-19 in Simulations on Real Mobility Data

摘要:

世界各地都采取了重大干预措施,以减缓SARS-CoV-2病毒的传播。大规模封锁人员流动可以有效减少传播,但代价是社会功能受到极大限制。我们表明,自然的人类运动是统计上的差异,疾病的传播是显着影响一小群活跃的个人和聚集场所。我们发现,针对这些流动性最强的个人和受欢迎的场所的干预措施降低了峰值感染率和总感染人口,同时保持了较高的社会活动水平。这些趋势在来自世界各地多个城市的不同规模、分辨率和模式的真实人类流动数据的模拟中得到了一致的体现。观察结果表明,与广泛的全面干预相比,基于人员流动网络效应的更多样化的战略在流行病控制和常规社会活动之间提供了更好的平衡。

英文摘要:

Major interventions have been introduced worldwide to slow down the spread of the SARS-CoV-2 virus. Large-scale lockdowns of human movements are effective in reducing the spread, but they come at a cost of significantly limited societal functions. We show that natural human movements are statistically diverse, and the spread of the disease is significantly influenced by a small group of active individuals and gathering venues. We find that interventions focused on these most mobile individuals and popular venues reduce both the peak infection rate and the total infected population while retaining high social activity levels. These trends are seen consistently in simulations with real human mobility data of different scales, resolutions, and modalities from multiple cities across the world. The observation implies that compared to broad sweeping interventions, more heterogeneous strategies that are targeted based on the network effects in human mobility provide a better balance between pandemic control and regular social activities.
