COVID-19引起的流动性变化（CS SI）

- 笔记
作为对COVID-19大流行病的回应，行为的自愿改变和对人类互动的管理限制都已经发生变化。这些措施旨在降低严重急性呼吸综合症冠状病毒2(SARS-Cov-2)的传播速度。我们使用匿名或去识别的移动设备位置来测量移动性，这是一个统计数据，代表一个特定人群中一个典型成员每天移动的距离。结果表明，在美国和全球，流动性已经发生了大幅减少。在美国，随着COVID-19威胁的发生和政府的具体指令，移动能力大幅下降。 美国 admin1(州)和 admin2(县)级的移动数据已经通过GitHub仓库(http / url)在知识共享属性(cc by 4.0)许可下免费提供。
原文题目Mobility Changes in Response to COVID-19
原文：In response to the COVID-19 pandemic, both voluntary changes in behavior and administrative restrictions on human interactions have occurred. These actions are intended to reduce the transmission rate of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We use anonymized and/or de-identified mobile device locations to measure mobility, a statistic representing the distance a typical member of a given population moves in a day. Results indicate that a large reduction in mobility has taken place, both in the US and globally. In the United States, large mobility reductions have been detected associated with the onset of the COVID-19 threat and specific government directives. Mobility data at the US admin1 (state) and admin2 (county) level have been made freely available under a Creative Commons Attribution (CC BY 4.0) license via the GitHub repository this https URL
