Arizona added nearly 2,200 cases of coronavirus overnight Sunday, putting the state above 54,000.

According to the Arizona Department of Health Services, there are 54,586 cases and 1,342 deaths of COVID-19 as of Monday morning, up 2,196 and three, respectively, from Sunday.

The Maricopa County Department of Public Health reports 31,490 cases and 603 deaths in Arizona’s most populous county.

The numbers of cases per 100,000 residents in the state is 750 as of Monday, using 2019 estimates from the U.S. Census Bureau. Maricopa County is below that at 706. Santa Cruz County is at 3,187 cases per 100,000 residents, the highest in the state after surpassing Navajo and Apache counties. Those two have rates of 2,738 and 2,950 per 100,000 residents, respectively.

Health officials have attributed the new cases to increased testing and to community spread of the virus.

Saying that data trends were headed in the wrong direction, Gov. Doug Ducey last week reversed himself and allowed local governments to impose requirements for people to wear masks in public to curtail spread of the virus. Most cities and counties have done that.

For most people, the new coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. But for some — especially older adults and people with existing health problems — it can cause more severe illness, including pneumonia, and death.
