Modification to reporting of COVID-19 metrics beginning April 4

Consistent with a change in federal requirements, beginning on Monday, April 4, 2022, the Connecticut Department of Public Health will no longer require the reporting of negative rapid antigen and rapid PCR test results for SARS-CoV-2. All positive test results from these tests must still be reported, as well as all positive and negative SARS-CoV-2 molecular test results.

Beginning on this date, test positivity will be calculated as a rolling seven-day test positivity by specimen collection date. All positive molecular test results are divided by all molecular test results (positive and negative) for the last seven days and multiplied by 100 to reach a percentage. In addition, the change in hospitalizations will be reported as a change between the last seven days, instead of a change in the last day.

This change will align Connecticut’s test positivity reporting with the same method used by the Centers for Disease Control and Prevention (CDC) and will not impact the ability to detect increases in COVID-19 cases due to new variants.
