虽然严格的社会距离措施已被证明在减缓COVID-19大流行方面有效,但随着限制的解除,第二波情景可能会出现。在这里,我们将匿名的、地理定位的流动性数据与人口普查和人口统计数据结合起来,建立了一个详细的基于agent的波士顿大都市地区SARS-CoV-2传播模型。我们发现,在一段时间内严格保持社会距离,然后进行强有力的检测、接触者追踪和家庭隔离,可以将疾病控制在卫生保健系统的能力范围内,同时使经济活动得以重新开始。我们的研究结果表明,在没有SARS-CoV-2群体免疫的情况下,基于加强检测和接触者追踪的反应系统可以在放松社会距离干预方面发挥重要作用。
While severe social distancing measures have proven effective in slowing the COVID-19 pandemic, second-wave scenarios are likely to emerge as restrictions are lifted. Here, we integrate anonymized, geo-localized mobility data with census and demographic data to build a detailed agent-based model of SARS-CoV-2 transmission in the Boston metropolitan area. We find that a period of strict social distancing followed by a robust level of testing, contact-tracing, and household quarantine could keep the disease within the capacity of the health care system while enabling the reopening of economic activities. Our results show that a response system based on enhanced testing and contact tracing can play a major role in relaxing social distancing interventions in the absence of herd immunity against SARS-CoV-2.
