"It spread like wildfire, a fire. Very, very scary," Prime Minister MIke De Wine said on Tuesday. "We know that our faith-based leaders want nothing more than to protect those who come to worship."
To illustrate how an infected person can spread the virus, government health professionals released a color chart showing how the cases radiated to someone who was not even on duty.
DeWine encouraged people to attend religious services using masks. He was mandated to use face masks for people 10 years and older on July 22. On Wednesday, he ordered children in schools to wear masks, with a few exceptions.
The governor said he would send letters to churches, mosques and synagogues to share important health information.
"It is important that whenever people gather, everyone should wear masks, practice social distance, wash their hands and while indoors, make sure there is good ventilation and airflow," he said.
In the case of fellowship spread from the worshiper at the undisclosed church, a 56-year-old man attended the service. A total of 53 people became ill, and 18 of the churchgoers spread it to at least one other person.
An occurrence of spread was a family in which a 34-year-old man became ill. His 31-year-old wife was also infected, as were four children aged 1 to 11.
The wife and two children of the 56-year-old worshiper mentioned by the governor also became ill. The state did not specify the severity of 91 people's diseases.
More than 96,000 people in Ohio have tested positive for the coronavirus.
