In response to the COVID-19 pandemic, forty-one states and the District of Columbia issued statewide stay-at-home orders. This study's findings indicate that statewide stay-at-home orders are least effective without mandatory face-mask provisions, and mandatory face masks are more effective than stay-at-home orders to reduce the number of COVID-19 infections. The analysis shows a moderate negative correlation between the number of confirmed COVID-19 infections and the number of mandatory face mask and face-covering provisions in statewide orders. A weak negative correlation between the number of confirmed COVID-19 and stay-at-home orders still in effect as of May 14, 2020. A very strong positive correlation was found between the number of confirmed COVID-19 infections and COVID-19 testing. A Stepwise multiple regression analysis was performed, in place of a Poisson regression, due to a failure to fit. The regression results indicate that confirmed COVID-19 infection numbers increased by 0.1639 infections each test performed and decreased by 33,723 because of mandatory face masks and face-covering provisions. Statewide stay-at-home orders were founded to be the least significant variable and removed by the Stepwise multiple regression analysis.
