论文摘要
社会距离仍然是与美国共同19日大流行作斗争的重要策略。但是，尚未完全量化特定状态级政策对迁移率和随后的COVID-19案例轨迹的影响。我们使用来自选择的Google用户的匿名和汇总的移动性数据，我们发现州级紧急声明导致远离居住地的时间减少了9.9％。实施一个或多个社会距离政策，下周的移动性降低了24.5％，随后的地位授权又减少了29.0％。在2至4周后增长的情况下，迁移率的降低与大幅降低有关。例如，在2周后，案件增长时，迁移率降低了10％与17.5％的降低有关。鉴于持续依赖社会距离政策以限制了Covid-19的传播，这些结果可能对试图在感染控制与这些政策的经济和社会后果之间的公共卫生官员可能有所帮助。
Social distancing remains an important strategy to combat the COVID-19 pandemic in the United States. However, the impacts of specific state-level policies on mobility and subsequent COVID-19 case trajectories have not been completely quantified. Using anonymized and aggregated mobility data from opted-in Google users, we found that state-level emergency declarations resulted in a 9.9% reduction in time spent away from places of residence. Implementation of one or more social distancing policies resulted in an additional 24.5% reduction in mobility the following week, and subsequent shelter-in-place mandates yielded an additional 29.0% reduction. Decreases in mobility were associated with substantial reductions in case growth 2 to 4 weeks later. For example, a 10% reduction in mobility was associated with a 17.5% reduction in case growth 2 weeks later. Given the continued reliance on social distancing policies to limit the spread of COVID-19, these results may be helpful to public health officials trying to balance infection control with the economic and social consequences of these policies.
