作為對COVID-19大流行病的回應，行為的自願改變和對人類互動的管理限制都已經發生變化。這些措施旨在降低嚴重急性呼吸綜合症冠狀病毒2(SARS-Cov-2)的傳播速度。我們使用匿名或去識別的移動設備位置來測量移動性，這是一個統計數據，代表一個特定人群中一個典型成員每天移動的距離。結果表明，在美國和全球，流動性已經發生了大幅減少。在美國，隨著COVID-19威脅的發生和政府的具體指令，移動能力大幅下降。 美國 admin1(州)和 admin2(縣)級的移動數據已經通過GitHub倉庫(http / url)在知識共享屬性(cc by 4.0)許可下免費提供。
原文題目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
