Arizona reported 939 new COVID-19 cases and 121 new known deaths Thursday as hospital admissions for the disease and percent positivity for testing continued to decline.
According to the U.S. Centers for Disease Control and Prevention’s COVID Data Tracker, Arizona’s 7-day average for new cases was Wednesday 15th among all states, after ranking first and second for most of January.
The state’s rate of new positive cases in the past seven days was 21.4 cases per 100,000 people, according to the CDC. New York City was the first with 50.5 cases per 100,000. The US mean for new cases was 19.7 cases per 100,000 people.
The state’s average daily COVID-19 deaths per 100,000 people over the past seven days ranked second in the nation on Wednesday, according to the CDC.
Arizona’s newly reported 121 deaths brought the known COVID-19 number to 15,814. The state passed 15,000 deaths on February 17, after recording 14,000 deaths on February 6 and 13,000 deaths on January 29, just one week after 12,000 and two weeks after 11,000 deaths. The state exceeded 10,000 known deaths on January 9. Arizona’s first known death from the disease occurred in mid-March.
Many of the deaths occurred days or weeks earlier as delays were reported and the death certificate matched.
In just over a year since the first Arizona case was announced, a total of 812,907 COVID-19 cases have been identified across the state. Relatively few cases were reported in February.
The Arizona data dashboard shows that 85% of all ICU beds and 89% of all inpatient beds in the state were in use on Thursday, with 24% of ICU beds and 16% of ICU beds outside of COVID-19 -Patients were occupied. Nationwide, 259 beds were available in the intensive care unit and 975 beds outside the intensive care unit.
Hospital stays for the disease have been falling for more than six weeks but remain at a relatively high level.
The number of patients hospitalized for known or suspected COVID-19 cases in Arizona stood at 1,385 on Wednesday, compared to 1,449 inpatients on Tuesday and well below the record of 5,082 inpatients on Jan. 11. By comparison, the highest number of COVID-19 hospitalizations in Arizona was a single day during the summer surge on July 13th was 3,517.
The number of patients with suspected or known COVID-19 in intensive care units across Arizona was 415 on Wednesday, compared to 430 on Tuesday and below the record high of 1,183 on Jan. 11. During the summer surge in mid-July, the intensive care unit was on use for COVID-19, which peaked at 970.
Arizonans with confirmed and suspected COVID-19 on ventilators hit 241 on Wednesday, compared to 253 on Tuesday and well below the record high of 821 on Jan. 13. During the summer surge, July 16 was the peak day for ventilator patient use with 687 patients.
On Wednesday there were 1,210 patients in the emergency room for COVID-19, down from the December 29th record of 2,341 positive or suspected COVID-19 patients in emergency rooms across the state.
The percent positivity, which relates to the percentage of positive COVID-19 diagnostic tests, has decreased, but varies somewhat depending on the type of measurement.
Last week, Arizona’s percent positivity stayed at 9% for the second straight week, according to the state, which has a unique way to calculate percent positivity. According to government data, the percent positivity was between 4% and 6% for much of August, September, and October.
Johns Hopkins University calculates the Arizona moving average for seven days as a percentage of positive results as of Thursday at 4.7%. It shows that the state’s percentage positivity peaked at 24.2% in December.
A positivity rate of 5% or less is considered a good measure of whether the spread of the disease is under control.
Arizona began its first COVID-19 vaccinations for Phase 1A in the week of December 14, but the process has been slow due to limited vaccine supplies. Registration is available in priority countries or for all Phase 1B individuals and in most locations for individuals aged 65 and over. Governor Doug Ducey said the vaccine was free for everyone.
As of Thursday, more than 1.1 million people nationwide had received at least one dose of vaccine, with about 465,500 people fully vaccinated against COVID-19 with two doses, according to state data.

Of those who tested positive since the Arizona pandemic began, 16% were younger than 20, 44% were 20-44, 15% were 45-54, 12% were 55-64, and 13% were over 65 years of age.
The laboratories performed 3,728,569 individual diagnostic tests for COVID-19, of which 14.5% were positive. This number includes both PCR and antigen testing. The percentage of positive tests had increased since mid-May but began to decrease in July and remained constant at 4% per state for several weeks. For the last full week it was 9%. The status numbers omit data from laboratories that do not report electronically.
The Arizona Department of Health includes likely cases such as people with a positive antigen test, another type of test used to determine current infection. Antigen tests (not related to antibody tests) are newer diagnostic COVID-19 tests that use a nasal swab or other fluid sample to test for current infections. Results are usually generated within 15 minutes.
A positive antigen test result is considered very accurate, but there is an increased chance of false negative results, says the Mayo Clinic. Depending on the situation, Mayo Clinic officials say that a doctor may recommend a polymerase chain reaction (PCR) test to confirm a negative antigen test result.
