Average daily COVID-19 case counts peaked at 4,148 to 4,377 cases from Jun 29 to Jul 2, leveled off to 3,609 to 4,160 cases from Jul 3 to 12, and further dropped roughly 75% from 3,506 cases on Jul 13 to 867 cases on Aug 7. Public health measures were then extended to the end of August to further stem virus transmission.
While the authors, from the CDC and ADSHS, said the public health efforts seemed to have successfully stemmed COVID-19 transmission, they cautioned against inferring that they caused the case count fluctuations, that there was universal compliance with the mitigation measures, or that more populous states would necessarily see the same results.
“Enhanced mitigation measures should be implemented by communities and persons to slow COVID-19 spread, particularly before a vaccine or therapeutic treatment becomes widely available,” the authors wrote. “State, local, and tribal officials are best positioned to continually monitor data and collaborate to determine the level and types of enhanced mitigation required.”
