It spread like wildfire, wildfire. Very, very scary," Gov. MIke De Wine said Tuesday. "We know that our faith-based leaders want nothing more than to protect those who come to worship."
To illustrate how one infected person can spread the virus, state health officials released a color graphic showing how the cases radiated to some who weren't even at the service.
DeWine urged people attending religious services to wear masks. He had mandated wearing face coverings for people 10 and older on July 22. On Wednesday, he ordered children in schools to wear masks, with a few exceptions.
The governor said he was going to send letters to churches, mosques and synagogues to share important health information.
It is vital that, any time people gather together, everyone wear masks, practice social distancing, wash hands, and while indoors, making sure there is good ventilation and airflow," he said.
