Native Americans, older people and men are dying in disproportionate numbers in Arizona from COVID-19, according to new data released by the state's health department.

Native Americans make up 16% of those who have died from COVID-19, among the cases for which race and ethnicity are known, according to data released by the Arizona Department of Health Services. The American Community Survey's 5-year estimates show about 4.6% of Arizonans are American Indian or Alaska Native.

The state announced it would provide additional data beginning Sunday on race and ethnicity in cases and deaths, numbers of cases by ZIP code and details on hospital and intensive-care unit capacity.

But the data is incomplete, particularly about coronavirus victims. The state says race is unknown for 63% of the coronavirus cases and 48% of those who have died.

The data does show a massive age disparity, however. Deaths are overwhelming in cases over age 65. Of the state's 115 deaths, 78 have been in this age category.

Those who have died are also more likely to be male than the broader Arizona population: 63% of deaths are male.

Of those who have tested positive for COVID-19, the majority are female, at 53%.

Only one person under age 45 has died in Arizona from COVID-19-related illness.

Twelve people age 45 to 54 have died. For those aged 55 to 64, the number of deaths is 24.

Cases by geographic location

The Navajo Nation has been hard hit by the outbreak, with 698 identified cases and 24 confirmed deaths as of Saturday evening. Tribal lands are in three states — northern Arizona, northwestern New Mexico and southern Utah — so it's unclear how many of those 24 deaths were in Arizona.

The Pascua Yaqui tribe in southern Arizona has confirmed two coronavirus deaths, and the Gila River Indian Community announced one COVID-19 related death.

The state also has published a map of cases by ZIP code.

State health officials provided precise numbers only in ZIP codes that have more than 10 cases. Of those areas, spots with the highest rates of cases per population included Page and Winslow near the Navajo Nation, a swath of Tucson's south side, and parts of Paradise Valley, north Phoenix and Scottsdale.

Those hot spots, however, probably do not represent the real locations of all those cases. If a patient's residence is unknown, state officials said, the case was mapped to the address of the provider or the reporting facility.

Officials did not respond to questions about how many such cases were mapped. And officials said they suppressed data from any ZIP code where more than 50 percent of the population is tribal residents, "pending tribal approval."

Hospital capacity data added to report

Additional data on the state's hospital capacity, including the number of beds and ventilators in use and available, shows that Arizona appears to be in a good position for now.

The state has nearly 2,000 intensive care unit beds available, with about 1,000 now in use. The state has about 2,215 emergency department beds, with about one-quarter in use.

Arizona has about 1,500 ventilators total, 365 of which are currently in use, the health department reported.

4.3% rise in confirmed cases Sunday

Arizona cases of COVID-19, the disease caused by the new coronavirus, now exceed 3,500, with 115 known deaths, according to the state data released Sunday.

Arizona's total identified cases rose to 3,539, according to the most recent state figures. That's an increase of 146 confirmed cases, or 4.3%, since Saturday, when the state reported 3,393 identified cases and 108 deaths.

Maricopa County's confirmed cases now total nearly 2,000, at 1,960. 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.

Community spread in Arizona, meaning cases with no identified source of infection, is now considered widespread, according to the state.

As of Sunday morning, the state reported death totals from the following counties: 48 in Maricopa, 29 in Pima, 19 in Coconino, eight in Navajo, four in Pinal and three in Apache. Mohave County reported two deaths, and Yavapai and La Paz reported one each, as of Saturday, although those did not appear on the state's dashboard.

While the state's dashboard shows Maricopa County with 1,960 cases, the county's dashboard shows 1,957. Maricopa County’s Department of Public Health provided more detailed information on its 1,957 cases:

Confirmed cases increased by 71 from Saturday to Sunday. Deaths increased by one, to 48.

The cases are 50% men and 50% women.

156 cases have been linked to long-term care facilities. Of those, 33% have been hospitalized and 13% have died.

29 long-term care facilities have at least one positive case.

Fifty-two 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%.

19%, or 381 cases, have been hospitalized.

6%, or 123 cases, have been in the intensive care unit. The hospitalization and ICU numbers include any cases that were 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, 136 were hospitalized and 47 were in the ICU. Among those over age 65, there were 172 hospitalized and 57 in the ICU.

Of the 48 deaths in Maricopa County, 11 were aged 45-64 and 37 were over age 65.

According to Sunday's state update, Pima County reported 622 identified cases. Navajo County reported 335 cases, while Coconino reported 243. Pinal County reported 163, Apache County reported 72, Yavapai County reported 63, Mohave County reported 30 and Yuma County reported 17.

Cochise County reported 15 cases, Santa Cruz County reported eight, La Paz County reported four, Gila County reported three, Graham County reported two and Greenlee County reported two, according to state numbers.

Curfew ends at 5 a.m. Monday on Navajo Nation

On the Navajo Nation, 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 is in effect on the nation. It began at 8 p.m. Friday and will last until 5 a.m. Monday, except for essential employees who are required to have documentation from their employer.
