Arizona combines PCR and antigen tests in the total tests figure reported on the state’s dashboard

Arizona regularly reviews and removes duplicate records which may occasionally result in minor decreases of cumulative figures.

The Recovered data point we report for Arizona reflects the number of COVID-19 patients discharged from the hospital and therefore does not represent the total number of people who have recovered from COVID-19, since many people with COVID are never hospitalized.

Negative test results reported in our API and CSVs are calculated by subtracting Positive PCR tests (people) from Total PCR tests (specimens) in the absence of better data.

On October 6, 2020, The Arizona Department of Health Services announced that they were removing cases who had been admitted to a hospital but had not been hospitalized from their total hospitalization counts. This results in a decrease of Arizona's cumulative hospitalizations.

As of September 25, 2020, Arizona’s total test timeseries is stored in our Total PCR Tests (People) field instead of Total PCR Tests (specimens), reflecting a response to our outreach to Arizona’s health department that it counts unique individuals tested. Arizona includes antigen tests in its totals figure, so if an individual received both an antigen and PCR test, they are counted only once. Additionally, as of September 25, 2020, Arizona's total test results are drawn from our Total PCR Tests (People) field instead of calculated via positive+negative.

On September 18, 2020, Arizona reported a policy change in the way they count people with positive antigen testing results to comply with CSTE case definitions. This appears to have resulted in a large increase in probable cases and also likely the reason where a decrease in confirmed cases was observed.

On September 16, 2020, Arizona added antigen testing into its main totals figure. This appears to have raised its Total Tests (PCR) number more than usual.

From July 18August 5, 2020, Arizona’s dashboard stopped displaying confirmed and probable breakdowns for Cases and Deaths, so we could not update Confirmed Cases, Probable Cases, Confirmed Deaths, or Probable Deaths during this period. We were still able to update the total data points for Cases (confirmed plus probable) and Deaths (confirmed plus probable). We will backfill the separate confirmed and probable case and death data if Arizona provides historical numbers.

On June 23, 2020, we updated our historical data for Cumulative hospitalized to match Arizona's dashboard data for "hospitalized by date admitted." Data for this metric is not typically reported until several days after admittance. Our daily updates will continue to compile Arizona’s overall number as of cumulative hospitalizations, regardless of date admitted.

Arizona and Missouri report only facilities with outbreaks, not actual cases, deaths, or facility names—this appears transparent, but doesn’t convey COVID-19’s true impact. County health depts (Maricopa, AZ and St. Louis, MO) provide both states’ most reliable source of LTC data.

September 1, 2020

But there is good news to report as well. The 7-day new-case average is declining in all four of our major hotspot states: AZ, CA, FL, and TX.

July 30, 2020

The hotspot states remain hotspots, even as their cases plateau a little or even decline. However, we’re now seeing more deaths reported in these states. Today, 773 deaths were reported by Arizona, California, Florida, and Texas alone.

July 29, 2020

We noted Arizona's falling case and completed test counts yesterday. It's worth recalling that on July 9, Governor Ducey said that his state would be doing 35k tests per day by the end of July. 7-Day Rolling Average: Tests reported, 7/9: 13,175 Tests reported, 7/23: 10,492

July 23, 2020

Arizona's cases are declining, and although testing has also fallen, the state's current hospitalization numbers are also down, which is unequivocally good. Still: the state’s two highest death tolls are Saturday (147) and today (134).
