  • A recent low test positivity rate of 1.6% in Ohio was caused after the state reported 521,000 test results on April 22, 2021. Prior to that single-day dump of cases, the state’s 7-day moving average for its positivity rate stood at 6%. The positivity will remain low for another three days before spiking after the massive amount of tests falls out of the 7-day calculation.
