  • COVID-19 incidence decreased following implementation of mitigation measures in Arizona. Prior to these measures, the average number of daily cases increased approximately 151% from June 1 to June 15, after which local officials enacted mitigation measures that included mask wearing (June 17), closures of bars, gyms, movie theaters, and water parks (June 29), and limiting restaurant capacity to <50% (July 9). The 7-day moving average of daily cases then peaked, stabilized and subsequently decreased by 75% from July 13 to August 7.
