[Cleveland.com] After an earlier rapid coronavirus test returned a positive result for Ohio Gov. Mike DeWine, a second coronavirus test for DeWine, Ohio First Lady Fran DeWine and members of his staff all have come back negative, the governor's office announced Thursday night.
The second round of testing was performed through a more sensitive test called a polymerase chain reaction, or PCR test, which detects genetic material from the new coronavirus, the governor's office said.
