Adjusted^ prevalence ratios and 95% confidence intervals comparing rapid riser* identification during June 1–September 30, 2020 by length of statewide closure (days)+, stratified by urbanicity.

Figure 2 Footnotes: ^Adjusted for population size; * Rapid riser counties were defined as those that met the following criteria: 1) >100 new cases in the last 7 days, 2) >0% change in the 7-day incidence, 3) a decrease of no more than 60% or an increase in the most recent 3-day COVID-19 incidence over the preceding 3-day incidence, and 4) a 7-day incidence/30-day incidence ratio >0.31. In addition, rapid riser counties met one or both of the following triggering criteria: 1) >60% change in 3-day incidence, or 2) >60% change in 7-day incidence. +Each statewide closure length category compared to reference category of statewide closure >59 days.
