New cases of COVID-19 in Arizona are slowing down, but deaths from the disease continue to be reported at high numbers.
On Friday, Arizona reported 9,077 new COVID-19 cases and 100 new known deaths.
Hospitalizations for the disease have remained high in recent weeks, with gradual decreases over the past week. Hospitals remain overwhelmed with high patient counts and stretched staff and resources.
On Thursday, 3,064 patients were hospitalized across Arizona for known or suspected COVID-19, still very high but continuing a steady decrease over the past week. Just 117 ICU beds were available across the state.
The number of known deaths in the state was 26,530 as of Friday after hitting 26,000 deaths one week earlier. The state surpassed 25,000 deaths on Jan. 13, 16 days after it reached 24,000 deaths on Dec. 28, which had come 17 days after it passed 23,000 deaths.
Arizona’s seven-day COVID-19 death rate per 100,000 people ranked 14th in the nation out of all states and territories as of Thursday, after ranking first on Wednesday, according to data from the US Centers for Disease Control and Prevention. The state’s overall pandemic death rate ranks third highest nationwide.
State data on breakthrough infections
The state in December began publicly disclosing data on breakthrough COVID-19 infections, and state officials say the data underscores the effectiveness of the vaccine.
The vast majority of cases, hospitalizations and deaths are among people not fully vaccinated.
Data from December show that 35.5% of cases, 20.5% of hospitalizations and 14.8% of COVID-19 deaths were among fully vaccinated people, and all the rest were unvaccinated people.
Unvaccinated people in Arizona had a 4.1 times greater risk of testing positive for COVID-19, 24.4 times greater risk of hospitalization from COVID-19 and 57.9 times greater risk of dying from COVID-19 in December compared with fully vaccinated people, per state data .
Case rates and death reports
Previous days this past week saw the following new case reports: 15,506 on Jan 29; 13,473 on Jan 30; 12,259 on Jan 31; 7,567 on Feb 1; 8,329 on Feb 2; and 7,794 on Feb 3.
Death reports for the past week were: 182 on Jan. 29; 23 on Jan 30; -1 on Jan 31; 140 on Feb 1; 24 on Feb 2; and 61 on Feb 3.
The Arizona Republic generally recaps the state’s daily numbers online in a COVID-19 updates blog and in a weekly recap story online on Thursdays or Fridays and in the newspaper on Sundays.
Arizona’s seven-day case rate per 100,000 people ranked 10th among all states and territories on Thursday, according to the CDC’s COVID-19 Data Tracker. Last week, it ranked ninth.
The omicron variant remains overwhelmingly dominant in Arizona, according to results from sequencing labs.
The state’s seven-day average for new reported COVID-19 cases was at 10,572 on Friday, compared with 18,208 a week ago and 19,823 two weeks ago. The previous record before this surge was about 9,800 in January 2021, according to state data.
Percent positivity, which refers to the percentage of COVID-19 diagnostic tests that are positive, varies somewhat based on how it’s measured. It’s been high in recent weeks, a sign of more community spread.

For most of December, Arizona’s percent positivity for COVID-19 testing was at 11% to 13%cdcd before rising to 22% for the week of Dec. It’s at 24% so far for the week of Jan. 30. The percentages are now conducted for all diagnostic tests, rather than for unique individuals tested, following a change to the state dashboard.
Johns Hopkins University calculates Arizona’s seven-day moving average of percent positives at 21.1% as of Friday.
A positivity rate of 5% or less is considered a good benchmark that the disease’s spread is under control.
The state’s overall COVID-19 death and case rates since Jan. 21, 2020, still remain among the worst in the country.
The COVID-19 death rate in Arizona since the pandemic began is 362 deaths per 100,000 people as of Thursday, according to the CDC, putting it third in the country in a state ranking that separates New York City from New York state. The US average is 268 deaths per 100,000 people as of Thursday, according to the CDC.
New York City has the highest death rate, at 460 deaths per 100,000 people, followed by Mississippi at 375.
Arizona surpassed 26,000 known deaths on Jan. 28 after passing 25,000 deaths on Jan. 13, 24,000 deaths on Dec. 28, 23,000 deaths on Dec. 11, 22,000 deaths on Nov. 23, 21,000 deaths on Oct. 27, and 20,000 deaths on Oct. 1.
The state exceeded 10,000 reported known deaths on Jan. 9, 2021. Arizona’s first known death from the disease occurred in mid-March 2020.
Many of the reported deaths occurred days or weeks before because of reporting delays and death certificate matching.
A total of 1,903,412 COVID-19 cases had been identified across the state as of Friday.
Hospitalizations dropping slightly
The Arizona data dashboard shows 93% of all ICU beds and 94% of all inpatient beds in the state were in use on Thursday, with 38% of ICU beds and 35% of non-ICU beds occupied by COVID-19 patients. Statewide, 117 ICU beds and 526 non-ICU beds were available.
The number of patients hospitalized in Arizona for known or suspected COVID-19 cases was at 3,064 on Thursday after decreasing over the previous week. A week earlier that number was at 3,559, the peak for this surge. The record was 5,082 inpatients on Jan. 11, 2021. The highest number of COVID-19 hospitalizations in a single day during the summer 2020 surge was 3,517 on July 13.
The number of patients with suspected or known COVID-19 in ICUs across Arizona has been relatively steady and was at 632 on Thursday, compared with 636 last week and 630 three weeks prior. That’s still far below the record high of 1,183 on Jan. 11, 2021. During the summer surge in mid-July 2020, ICU beds in use for COVID-19 peaked at 970.
Arizonans with confirmed and suspected COVID-19 on ventilators were at 334 on Thursday. The record-high 821 was reached on Jan. 13, 2021. During the summer 2020 surge, July 16 was the peak day for ventilator use, with 687 patients.
Thursday saw 1,797 patients in Arizona emergency rooms for COVID-19, below the record high from Jan. 11, when 2,589 positive or suspected COVID-19 patients were seen in emergency departments across the state.
Vaccination update
Arizonans aged 5 and older are eligible to get the Pfizer vaccine, while the Moderna and Johnson & Johnson vaccines are approved for those 18 and older. Many individuals are eligible for booster doses, too.
The state reported more than 4.9 million people in Arizona — about 68.6% of the total state population — had received at least one vaccine dose as of Friday, with nearly 4.2 million residents fully vaccinated against COVID-19. The state’s data dashboard now separates out doses administered to Arizona residents versus all doses administered in the state.
Arizona’s rate of fully vaccinated people out of the total population is 59%, which is behind the national rate of 64%, according to the CDC as of Thursday.
Out of the vaccine-eligible population, people ages 5 and older, 62.7% of those in Arizona are fully vaccinated, compared with 68% at the national level, CDC data shows.
Health experts strongly recommend booster shots for those eligible, especially with the omicron variant spreading. About 40.5% of fully vaccinated Arizonans over the age of 18 had received a booster shot as of Thursday, below the national rate of 45.1% for that same age group.
What to know about Friday’s numbers
Reported cases in Arizona: 1,903,412.
Daily cases are grouped by the date they are reported to the state health department, not by the date the tests were administered.
Cases by county: 1,203,219 in Maricopa; 238,526 in Pima; 123,764 in Pinal; 60,096 in Yuma; 54,367 in Mohave; 45,689 in Yavapai; 41,214 in Coconino; 36,039 in Navajo; 29,071 at Cochise; 20,861 in Apache; 16.112 in Gila; 16,032 Santa Cruz; 11,423 at Graham; 4,898 in La Paz; and 2,100 in Greenlee, according to state numbers.
The rate of cases per 100,000 people since the pandemic began is highest in Navajo County, followed by Graham, Gila, Apache and Maricopa counties, per state data. The rate in Navajo County is 31,942 cases per 100,000 people. By comparison, the US average rate since the pandemic began is 22,773 cases per 100,000 people as of Thursday, according to the CDC.
The Navajo Nation reported 50,628 cases and 1,620 confirmed deaths as of Thursday. The Navajo Nation includes parts of Arizona, New Mexico and Utah.
The Arizona Department of Corrections reported 14,574 inmates had tested positive for COVID-19 as of Thursday, including 2,470 in Tucson, 2,271 in Eyman, 2,231 in Yuma, 1,537 in Lewis and 1,148 in Douglas; 53,041 inmates statewide have been tested. A total of 4,810 prison staff members have self-reported testing positive, the department said. Fifty-six incarcerated people in Arizona have been confirmed to have died of COVID-19, with 10 additional deaths under investigation.
The race/ethnicity breakdown of cases since the start of the pandemic in 2020 has been 38% white, 29% Hispanic or Latino, 5% American Indian, 4% Black and 2% Asian/Pacific Islander. Race/ethnicity of positive cases since the onset of the pandemic is unknown in 16% of cases, and listed as other race in 6% of cases.
Of those who have tested positive in Arizona since the start of the pandemic, about 21% were younger than 20, 43% were 20-44, 13% were 45-54, 11% were 55-64 and 11% were age 65 or older.
Laboratories had completed 17,661,661 total diagnostic tests for COVID-19 as of Friday, 12.3% of which have come back positive. That number includes both PCR and antigen testing. Percent positivity is at 24% so far for the week of Jan. 30. The state numbers leave out data from labs that do not report electronically.
The state Health Department includes probable cases as anyone with a positive antigen test, another type of test to determine infection. Antigen tests (not related to antibody tests) use a nasal swab or another fluid sample to test for current infection. Results are typically produced within 15 minutes.
A positive antigen test result is considered very accurate, but there’s an increased chance of false-negative results, Mayo Clinic officials said. They say a doctor may recommend a PCR (polymerase chain reaction) test to confirm a negative antigen test result.
Arizona as of Thursday had the 12th highest overall case rate in the country since Jan. 21, 2020. Ahead of Arizona in cases per 100,000 people since the pandemic began are Rhode Island, North Dakota, Alaska, Utah, Tennessee, South Carolina, New York City, Kentucky, Wisconsin, Arkansas and Florida, according to the CDC.
Arizona’s infection rate is 25,919 cases per 100,000 people, according to the CDC. The national average is 22,773 cases per 100,000 people, although the rates in states hard hit early in the pandemic may be an undercount because of a lack of available testing in March and April 2020.
