In half of the eight newly red counties, DeWine said outbreaks were related to weddings and funerals.
DeWine said health officials across the state have reported that laxed social distancing, not enough mask-wearing and not following quarantine guidance.
There are 42 counties considered “high incidence” and the governor said, “If you lived in one of these counties, you would worry about because either they have a high incidence or they are a red county ... these are the counties that we’re most particularly concerned about."
Hamilton, Butler and Warren counties are among those counties.
The concern, DeWine said he’s concerned for the safety of schools, even though they are taking measures to decrease risk to the students.
“Our schools are a reflection of our communities, and if there is wide-spread spread the schools simply have no way of keeping it out," DeWine said.
