Last week marked the largest week-to-week increase of coronavirus cases in both Arizona and Pima County since the pandemic began, and Banner Health is reporting its ICUs are at full capacity in Maricopa County and rapidly approaching full capacity in Tucson.

New, confirmed cases in Arizona totaled 4,500 from May 24 to May 30, according to the Arizona Department of Health Services, as of Saturday morning. That’s nearly a 50% increase from the week before.

In Pima County, cases totaled 481 over the same period, marking an 85% increase from the previous week.
