The Arizona Department of Health Services is reporting over 265,000 cases of COVID-19 as of Tuesday morning.

In Arizona, there are 165,934 cases and 3,408 deaths of the novel coronavirus, up 2,107 and 104 from Monday morning, respectively. That computes to a 2.05% death rate of confirmed cases in the state.

The number of cases could be far higher because many people have not been tested, and some can be infected without feeling sick.

The Maricopa County Department of Public Health reports 110,769 cases and 1,809 deaths in Arizona’s most populous county. State and county numbers differ depending on reporting times.

Maricopa County shows a case rate of 2,485 cases per 100,000 residents, using 2019 estimates. The state rate is 2,280. Santa Cruz County has the highest at 5,452 cases per 100,000 residents.

The coronavirus causes mild or moderate symptoms such as fever and cough for most people. The vast majority of people who are diagnosed with COVID-19 recover.

But for some — especially older adults and people with existing health problems — it can cause more severe illness including pneumonia, and death.

Navajo Nation

Hundreds of people who had been on paid leave from their jobs with the Navajo Nation's gambling enterprise won't be paid after Monday.

Brian Parrish, who heads the Navajo Nation Gaming Enterprise, said 900 employees began receiving letters and phone calls over the weekend about the layoffs.

Another 125 employees will be paid for another week, he said. A skeleton crew will remain on the payroll to handle human resources work, security, management and finances, Parrish among them.

The enterprise had been preparing to reopen its three casinos in northwestern New Mexico, and a resort casino and new travel center east of Flagstaff when the tribal president extended a closure of some executive offices. That order now expires in mid-August.

The ability to continue paying 1,180 employees had been a source of pride for the gambling enterprise.

The revenue from tribal casinos often is considered a stand-in for property tax that isn't paid on reservations. It helps fund tribal governments and social services like health care.

Mr. Parrish said the Navajo enterprise exhausted its cash reserves and money it received from the federal Paycheck Protection Program to pay employees and no longer can afford it.

The enterprise has submitted proposals to Navajo leaders for a share of federal coronavirus relief money that went directly to tribal governments. The leaders are considering a wide range of proposals that add up to more than the amount available.

"We have enormous trust and faith in our leadership," Mr. Parrish said. "They've got a lot of needs to balance."

The Navajo Nation once had one of the highest per-capita rates of coronavirus infections in the U.S. The daily number of reported cases has declined overall, but nighttime curfews, weekend lockdowns and a mask mandate remain because of recent surges in COVID-19 off the reservation.

Tribal health officials on Monday reported 21 new confirmed cases of COVID-19 and two additional deaths. The total number of people infected on the reservation now stands at 8,912 with 441 known deaths.

Tribal health officials said 77,741 people have undergone testing and 6,554 have recovered from the virus.
