question: What is already known about this topic? Universal masking and avoiding nonessential indoor spaces are recommended to mitigate the spread of COVID-19. What is added by this report? Mandating masks was associated with a decrease in daily COVID-19 case and death growth rates within 20 days of implementation. Allowing on-premises restaurant dining was associated with an increase in daily COVID-19 case growth rates 41-100 days after implementation and an increase in daily death growth rates 61-100 days after implementation. What are the implications for public health practice? Mask mandates and restricting any on-premises dining at restaurants can help limit community transmission of COVID-19 and reduce case and death growth rates. These findings can inform public policies to reduce community spread of COVID-19.
