Statewide, there’s been about 26,000 coronavirus tests per million residents as of Tuesday, while Orange County has had 17,000 tests per million residents, said Andrew Noymer, an associate professor of public health at UC Irvine. “That is a pretty big difference. Orange County’s pretty far behind,” Noymer said in an interview Tuesday. “Orange County should aspire to do better.” “It’s through testing that we’re going to keep track of the evolving epidemic, and so we should always aspire to do better. And clearly we’re below average statewide,” he added.
