Fig. 4From: Mobility was a significant determinant of reported COVID-19 incidence during the Omicron Surge in the most populous U.S. Counties Changes in Mobility Indicators ( \(\varDelta\) Mobility, Left Axis) and Changes in Reported COVID-19 Cases (\(\varDelta\)Â Incidence, Right Axis) in Less Extensive and More Extensive Mobility Decline Counties, Weeks Ending December 6, 2021, Through February 28, 2022. Less extensive mobility decline counties are identified as \(X\) = 0, while more extensive mobility decline counties are identified as \(X\) = 1. For both mobility and incidence, the figure plots the change from the week ending 12/6/21. Among less-extensive-decline (\(X\) = 0) counties, incremental incidence peaked during the week ending 1/17/22. Among more-extensive-decline (\(X\) = 1) counties, incremental incidence peaked earlier during the week of 1/10/22 and declined earlierBack to article page
