At least 91 people contracted coronavirus after a church service in Ohio.
A 56-year-old man who tested positive is single-handedly responsible for the spread.
Ohio Gov. Mike DeWine took to Facebook to share a visual representation of the virus’ spread over a three-week period across five counties from the date of the church service in mid-June.
53 of the 91 people who showed symptoms of COVID-19 attended the same church service in Ohio county, according to NBC.
18 of the 53 infected at the service spread the virus to at least one other person.
The 56-year-old responsible for infecting everyone also got his wife, son, and daughter sick.
"It spread like wildfire," the governor said at a news conference on Tuesday where he called the graphic of the spread “very, very scary."
"All it takes is one person to cause tremendous COVID-19 spread,” he noted in the Facebook post.
Rachel Feeley, a spokeswoman for the Ohio Department of Health, did not provide the name of the church or other details explaining that those exposed were notified via contract-tracing.
This specific case happened in Ohio, but DeWine warned that it can happen anywhere, which is why he encourages everyone to “wear masks and social distance whenever you gather — including at worship services.”
DeWine listed other examples of how easily the virus spreads at events and functions where a larger group of people is present and not practicing proper safety precautions.
"None of us want to stay away from our families and of course, it's natural to want to show affection when you see them," he tweeted on Tuesday with the reminder that the virus is “lurking” and that we should show love by protecting others.
DeWine tested negative for coronavirus on Thursday, hours after another test earlier in the day indicated a positive result. The results came from a different type of test that DeWine took in Columbus, considered to be more accurate than the quicker test he took earlier on Thursday.
DeWine first tested positive for COVID-19 ahead of a planned visit Thursday from President Trump in Cleveland, his office announced Thursday afternoon.
He will be retested on Saturday, according to NBC.
