Strong Social Distancing Measures In The United States Reduced The COVID-19 Growth Rate

This study evaluated the impact of social distancing measures on the growth rate of confirmed COVID-19 cases across US counties between March 1, 2020 and April 27, 2020.  The study predicted that COVID-19 spread would have been 10 times greater—meaning 10 million more cases—by Apr 27 without shelter-in-place orders. The study also found that without additional measures such as event bans, school closures, and closures of other venues such as restaurants and gyms, COVID-19 spread would have been 35 times greater, potentially resulting in 35 million more cases.
