The state had 266,562 COVID-19 cases—an increase of 1,399 from the previous day and 12 newly reported deaths, bringing the number of statewide virus-related deaths to 6,240 on Nov. 12, according to data from the Arizona Department of Health Services.
The number of diagnostic tests reported in Maricopa County as of Nov. 12 was 9,499 with 6.68%—or 635 tests–coming back positive. Those tests include polymerase chain reaction, known as PCR, tests and antigen tests. The PCR test determines an active case of COVID-19, the other kind of testing data the state tracks is related to serology—or antibody—tests, which determines if a person has been infected in the past with the virus. Antigen tests "may not be as accurate or able to run as many patient samples per day, however, the quick results provide the ability to rapidly triage and make decisions," according to ADHS.
The county also reported 20 new deaths Nov. 10 and 11, bringing the county's death toll to 3,754, according to data from the Maricopa County Department of Public Health. The county did not report numbers on Veterans Day for Nov. 10 and combined the two days for the current report.
Of the county's 3,754 known deaths, 1,275 are tied to long-term care facilities, making up 33.96% of the county's total COVID-19-related deaths.
The state and county also track hospitalization data. In Maricopa County, 8% of the county's total cases resulted in hospitalization as of Nov. 9. The county tracks intensive care unit, or ICU, data separately, and 1% of the county's total cases have resulted in admittance to the ICU. Statewide, as of Nov. 10, ADHS reported 8% of the state's cases have resulted in hospitalization—22,576 cases across the state.
