Arizona's death toll related to the new coronavirus rose to 15, according to data released by the Arizona Department of Health Services on Saturday morning.

The number of reported cases around the state also rose to 773.

As of Friday, there were 13 deaths and 665 reported cases around the state. Cases grew from Friday to Saturday by roughly 16%.

On Saturday, Pima County announced an additional coronavirus-related death, bringing the county total to five.

The man was a hospice patient between the age of 18 and 40, the county said.

It wasn't immediately clear whether the Pima County death was one of the two additional deaths announced by the state Saturday morning.

Maricopa County reported a growth of 53 cases, with 96 of the 452 cases in the county requiring hospitalization.

At a Wednesday press conference, state Health Director Dr. Cara Christ said that if infections continue at their current pace, illnesses would peak in April and hospitalizations would peak in May.

"Arizona is still in the opening stages of its COVID-19 outbreak, and the number of cases within the state will increase significantly," Christ said.

Gila, Mohave counties announce new cases

Gila County confirmed the county's first positive case of COVID-19 Friday.

The woman, a Payson resident in her 40s, has "predominantly self-isolated" since she first showed symptoms, according to the Gila County Public Health Department.

The case appears to be travel-related and there was no evidence of community spread as of Friday, the health department said.

Local health officials were investigating the case and the woman's close contacts.

The diagnosis prompted officials to announce that bars, movie theaters, indoor gyms and fitness clubs would immediately be closed to the public in order to comply with Gov. Doug Ducey's executive order.

All restaurants were ordered to close their on-site dining at the close of business on Friday until further notice.

Pick-up, delivery and drive-thru operations are still permitted in the county.

Cafeterias at nursing homes, hospitals and similar facilities as well as soup kitchens are not subject to the restrictions, the county said.

Mohave County announced its sixth case of COVID-19 on Saturday, the newest case in the Kingman area.

The adult patient is recovering at home and has been self-quarantined, according to a county press release. Mohave County Public Health nursing staff is in the process of contacting the person to implement monitoring and launch a contact investigation, the county said.

Two of the Mohave County cases are in Lake Havasu City, one is in Bullhead City and three are in Kingman.

State numbers paint incomplete picture

The number of cases is likely much higher than official numbers suggest. People have reported trouble getting tested, as health professionals confront confusion over who to test and a lack of supplies.

And on Wednesday, the state issued new guidance on testing to primary care providers saying they should "consider removing this diagnostic 'tool' from their toolbox and managing patients with respiratory conditions as if they have COVID-19."

The state health department's publicly reported numbers only provide positive test results from private labs, not the total number of people tested, leaving the online data incomplete.

The state has seen over 6,600 Arizonans get tested, most of which have been done by private labs, Christ said at Wednesday's briefing. The state's lab has run 420 tests.

Testing is limited to people in high-risk groups and those showing symptoms. The state is prioritizing health care and "critical infrastructure" workers.
