State and county-wide numbers

While Arizona COVID-19 death rates have remained just below 2% since late May, the rate of positive tests have increased dramatically in the last month, from 5.28% on July 1 to 11.4% on July 28, according to Mayo Clinic data.

Maricopa County has seen 580,692 total cases since the start of the pandemic, an increase of 7,610 cases since last Friday. 

Thirty-eight people have died in that same period, bringing the total to 10,446 countywide COVID-19 fatalities since pandemic began, according to ADHS data.

Percent positivity is at 14%, which county health officials consider “high transmission.” Last Friday, July 23, percent positivity was 12%, and the Friday before, transmission was only 9%.

Data collected by the county between July 18 and July 24 show 159 positive cases per 100,000. Last Friday, July 23, ADHS reported 114 cases per 100,000 and the Friday before, just 77 positive cases per 100,000 were reported.

Weekly updates

The Centers for Disease Control updated its mask guidance Tuesday, recommending even fully vaccinated people wear masks indoors in areas with substantial or high transmission rates due to the more contagious Delta variant.   

Previous CDC guidance allowed fully vaccinated people to be mask-less in public spaces.

The Arizona Legislature has banned public and charter schools from mandating masks, and Gov. Ducey has signaled he will not reverse course despite updated guidance from the CDC.

The Arizona Department of Health Services director, Dr. Cara Christ announced her resignation on Aug. 27 to join Blue Cross Blue Shield of Arizona. Her resignation comes just one day after Christ suggested Arizona schools follow updated CDC guidance on masks. She was appointed as ADHS director by Gov. Ducey in 2015.
