Data notes

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

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.

From July 18–August 5, 2020, Arizona’s dashboard stopped displaying confirmed and probable breakdowns for cases and deaths. We will backfill this data if Arizona provides historical numbers.

On July 28 and July 29, 2020, we noticed that Arizona's numbers for their Now hospitalized decreased slightly, while those for Ever hospitalized increased significantly. The state offered no explanation.

On August 30 and August 31, the Arizona Department of Health removed duplicate case records from their data. As a result, total deaths decreased by 1 on August 31, and cumulative hospitalizations decreased on August 30 and August 31.

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.

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

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 comprehend the total number of people who have recovered from COVID-19.

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.
