Surprise!

A person in Kentucky attended a “coronavirus party” that defiantly flouted social-distancing warnings — and then tested positive for COVID-19, the state’s governor said Tuesday.

A group of adults in their 20s intentionally got together “thinking they were invincible,” blatantly ignoring Kentucky’s guidance to practice social distancing, Gov. Andy Beshear said at a press conference.

“Anyone who goes to something like this may think that they are indestructible,” Beshear said. “But it’s someone else’s loved one that they are going to hurt.

“Don’t be so callous as to intentionally go to something and expose yourself to something that can kill other people,” he said.

“We ought to be much better than that.”

Beshear didn’t say where the person is from or where the party took place. He said he didn’t want to identify the person, who “made a mistake.”

But “I do hope it encourages others to act differently,” he added of the situation.

The infection was one of 39 new coronavirus cases reported in the Bluegrass State on Tuesday, bringing its total to 163, according to the Louisville Courier Journal.

Four people in the state have died from the disease.
