Pima County has conducted an in-depth analysis of the case investigation reports during the pandemic. The detailed report ties the case investigation reports to the various policies that were implemented by both Pima County and the state during the pandemic.
The analysis provides evidence that many of the interventions were successful. Data from the last 3 weeks provides an early indication that a larger share of recent cases originated in closed indoor environments that formerly had some interventions in place- which were abruptly removed by the Governor and Director Christ.
I encourage you to take a look a their analysis this week. Here is the report.
