为了控制未来的疫情并调整部分封锁,需要更好地了解 COVID-19 大流行如何应对社会疏远措施。我们提出了表征 COVID-19 流行病学的关键参数与九个选定的欧洲国家的社会疏远努力之间的定量关系。流行病学参数是从每日死亡人数数据中提取的,而缓解措施是根据手机跟踪数据估算的。基本再生数()的下降以及疫情初始指数扩张阶段的持续时间与流动性减少的程度密切相关。利用这些关系,我们解读了社交距离的时间和程度对大流行的总死亡负担的相对影响。
A better understanding of how the COVID-19 pandemic responds to social distancing efforts is required for the control of future outbreaks and to calibrate partial lock-downs. We present quantitative relationships between key parameters characterizing the COVID-19 epidemiology and social distancing efforts of nine selected European countries. Epidemiological parameters were extracted from the number of daily deaths data, while mitigation efforts are estimated from mobile phone tracking data. The decrease of the basic reproductive number () as well as the duration of the initial exponential expansion phase of the epidemic strongly correlates with the magnitude of mobility reduction. Utilizing these relationships we decipher the relative impact of the timing and the extent of social distancing on the total death burden of the pandemic.
