The report “Decline in COVID-19 Hospitalization Growth Rates Associated with Statewide Mask Mandates — 10 States, March–October 2020” contained several errors.
On page 212, in the first paragraph, the fifth sentence should have read “After mask mandates had been implemented for ≥3 weeks, hospitalization growth rates declined by 5.6 percentage points among persons aged 18–39 years (95% CI = 0.9–10.4) and those aged 40–64 years (95% CI = 1.0–10.2).”
On page 213, in the first complete paragraph of the right-hand column, the second sentence should have read “The overall COVID-19–associated hospitalization growth rates among all adults declined 2.4 percentage points (p-value = 0.04) <3 weeks after the implementation week and declined 5.0 percentage points (p-value <0.01) during the period ≥3 weeks after the implementation week (Table 2).”
On pages 213–214, the second complete paragraph of the right-hand column should have read “Among persons aged 18–39 years, the hospitalization growth rates <3 weeks after the implementation week were lower than were those during the <4 weeks before the implementation week and the implementation week (reference period) when no mask mandate existed, but the estimated percentage point difference (–2.2) was not statistically significant (p-value = 0.30) (Figure) (Table 2). However, in this population, mask mandates were associated with a statistically significant 5.6 percentage-point decline in COVID-19 hospitalization growth rates (p-value = 0.02) ≥3 weeks after the implementation week. Among adults aged 40–64 years, mask mandates were associated with a 2.9 percentage-point reduction in COVID-19 hospitalization growth rates (p-value = 0.03) <3 weeks after the implementation week. Hospitalization growth rates declined by 5.6 percentage points (p-value = 0.02) during ≥3 weeks after the implementation week. Among adults aged ≥65 years, COVID-19 hospitalization growth rates declined <3 weeks after the implementation week (1.2 percentage points) and ≥3 weeks after the implementation week (0.7 percentage points); however, the declines were not statistically significant.”
On page 214, there were multiple errors in Table 2. The corrected table is as follows:
On page 215, the second paragraph of the Summary should have read “During March 22–October 17, 2020, 10 sites participating in the COVID-19–Associated Hospitalization Surveillance Network in states with statewide mask mandates reported a decline in weekly COVID-19–associated hospitalization growth rates by up to 5.6 percentage points for adults aged 18–64 years after mandate implementation, compared with growth rates during the 4 weeks preceding implementation of the mandate.”
The Supplementary Table (https://stacks.cdc.gov/view/cdc/101127) should have listed the date of statewide reopening for Michigan as June 1, 2020.
