A stay-at-home order in Arizona expired May 15 and two weeks later — between June 1 and June 15 — the daily average number of COVID-19 cases jumped by 151%, the report says. The incubation period for a person exposed to the SARS-CoV-2 virus to develop COVID-19 is approximately two days to two weeks.

The spike in cases ended up overwhelming the state’s health care system with a surge of extremely ill COVID-19 patients needing care.

On June 6, as COVID-19 hospitalizations in Arizona climbed, Christ sent a letter to hospitals in the state urging them to “fully activate” their emergency plans.

The number of COVID-19 cases in Arizona peaked between June 29 and July 2, stabilized between July 3 and July 12, and declined by approximately 75% between July 13 and August 7, the report says.
