Arizona cases of COVID-19, the disease caused by the new coronavirus, now exceed 3,300, with 108 known deaths, according to new numbers released Saturday by the Arizona Department of Health Services.

Arizona's total identified cases rose to 3,393, according to the most recent state figures. That's an increase of 281 confirmed cases, or 9%, since Friday when the state reported 3,112 identified cases and 97 deaths.

Maricopa County's confirmed cases now exceed 1,800. All of Arizona's 15 counties have reported at least one case.

The number of Arizona cases likely is higher than official numbers suggest because of limits on supplies and available tests, which led to the state issuing guidelines that restrict who should be tested.

As of Saturday morning, the state reported death totals from the following counties: 47 in Maricopa, 29 in Pima, 15 in Coconino, seven in Navajo and three each in Pinal and Apache. Mohave County reported two deaths and Yavapai and La Paz reported one each, though those did not appear on the state's dashboard.

The state Health Department website says both state and private laboratories have completed a total of 40,530 tests for COVID-19, according to the number posted Saturday on the agency website.

The distribution of cases appears to align with the number of tests done. For instance, the age group with the highest percentage of cases, those aged 20 to 44, also are the age group that has had the most tests.

Most COVID-19 tests come back negative, the state's dashboard shows, with only 8% of tests coming back positive. Of the statewide identified cases, 47% are men and 53% are women. Previously, the majority of cases were men.

The state recorded 1,891 positive cases in Maricopa County as of Saturday morning, but Maricopa County’s Health Department only recorded 1,886. The county provided more detailed information on its cases:

Confirmed cases increased by 145 from Friday to Saturday.

144 cases have been linked to long-term care facilities.

Forty-eight people under age 19 have tested positive.

People aged 20 to 44 make up 40% of positive cases, followed by people 45-64 years old at 34% and people 65 or older at 23%.

20%, or 372 cases, have been hospitalized.

6%, or 120 cases, have been in the intensive care unit. The hospitalization and ICU numbers include any case that was in the hospital or ICU at any time during their illness, the county says.

The likelihood of being hospitalized or in the ICU increases with age. Of those aged 20-44, 72 were hospitalized and 19 were in the ICU. For people aged 45-64, 134 were hospitalized and 47 were in the ICU. Among those over age 65, there were 203 hospitalized and 54 in the ICU.

Of the 47 deaths in Maricopa County, 11 were aged 45-64 and 36 were over age 65.

Cases rise in other counties

According to Saturday's state update, Pima County reported 591 identified cases. Navajo County reported 321 cases, while Coconino reported 238. Pinal County reported 146, Yavapai County reported 63, Apache County reported 66, Mohave County reported 30 and Yuma County reported 15. Officials in Yuma County reported its cases at 18 on Thursday afternoon.

Cochise County reported 13 cases, Santa Cruz County reported eight, La Paz County reported four, Gila County reported three, and Graham and Greenlee counties each reported two, according to state numbers.

All counties but Yuma, La Paz, Gila and Graham saw an increase in their cases from Thursday.

The Arizona Republic contacted all 15 counties for numbers on hospitalizations, which is only available online for several counties. Yuma County will not provide the information, and officials in Navajo County and Apache County said they do not have the information.

The data includes all cases ever hospitalized, not just current hospitalizations:

Pima County: 97 known hospitalizations and 32 in the ICU as of Wednesday.

Pinal County: 32 known hospitalizations and 8 in the ICU as of Friday.

Yavapai County: six known hospitalizations as of Monday.

Cochise County: three known hospitalizations as of Monday.

Mohave County: one known hospitalization as of March 31.

Graham, Santa Cruz, La Paz, Gila and Greenlee counties: no known hospitalizations.

The Navajo Nation announced Saturday evening it had 698 identified cases, with 24 confirmed deaths. Of the 698 cases, 481 involve residents on tribal land in Arizona counties. The Navajo Nation includes parts of Arizona, New Mexico and Utah.

A 57-hour curfew took effect for the nation at 8 p.m. Friday and will last until 5 a.m. Monday. The curfew excludes essential employees who are required to have documentation from their employer. Anyone who violates the curfew will be cited by Navajo police and may have to pay a fine up to $1,000 and/or spend 30 days in jail.

New rapid test kits will be available at Navajo-area Indian Health Service facilities and tribally operated health care centers in the next few days. The new testing method will allow for test results within several minutes, instead of the current turnaround time of two to four days.

"Quicker test results will likely result in even higher numbers of positive cases, but it will help to identify those who have the virus and begin to mitigate the cases much quicker. We must do better," Navajo Nation President Jonathan Nez said in a statement. "If we all stay home this weekend, the spread will lessen."

The White Mountain Apache Tribe announced its first identified positive case of COVID-19 on the Fort Apache Indian Reservation northeast of Phoenix last week.

The Pascua Yaqui tribe in southern Arizona had confirmed two coronavirus deaths last week.

Gila River Indian Community Gov. Stephen Roe Lewis announced on April 4 the community's first COVID-19 related death.

Six cases in Arizona prisons

The Arizona Department of Corrections on Saturday said that six inmates have tested positive for COVID-19, up two from Friday evening. The six cases span four facilities, with two cases in Florence, two in Eyman, one in Tucson and one in Marana.

The corrections department had tested 78 inmates as of Saturday afternoon, with 64 negative cases and eight pending out of a total population of more than 41,500.

Both legal and non-legal visitations have been suspended through May 13, at which point the department will reassess the situation. The department said CenturyLink is giving inmates two additional 15-minute calls for free each week visitation is restricted.
