Cumulative Reported COVID-19 Cases per 100 Population During January 10 Through February 28, 2022 ( \(\varDelta\) Incidence) Versus the Change in the Mobility Indicator During December 20, 2021, Through January 3, 2022 (\(\varDelta\) Mobility), Plotted for 111 Counties. The size of each datapoint reflects the county population. Cumulative reported COVID-19 cases are plotted on a logarithmic scale. The weighted least squares fitted line is shown in red. The estimated slope, corresponding to the parameter \(\theta\) in Eq. (2) was 0.0124 with 95% CI (0.0060, 0.0187). That is, every additional 1-point reduction in the mobility indicator was associated with a 1.24% decline in cumulative reported cases per 100 persons. The outlier in the plot is identified as Cuyahoga County, Ohio. The vertical axis plots cumulative case incidence from the week ending January 10 onward. Cumulative incidence for the entire Omicron wave, from the week ending December 6, 2021, averaged 9 per 100 population
