A cheating UK hubby is “in a blind panic” over his extramarital affair — now that he has contracted the coronavirus on a secret trip to Italy with his mistress, according to a new report.

The unnamed patient, in his late 30s — described as “well-heeled and with a high-flying job” — told his wife he was away on a business trip within the UK, the Sun reported.

When the man returned home, he began showing symptoms of the deadly bug, and tests confirmed that he was in fact infected, according to the report.

“This patient is the talk of public health officials,” a source with knowledge of the situation told the outlet. “His case would be funny if it wasn’t quite so serious.”

“The man confessed [to doctors] what he’d been up to in Italy, and that his wife has no idea,” the source added. “She thinks he just picked up the disease on his business trip away.”

The man is expected to survive the infection — “unlike his extramarital relationship,” the source told the outlet.

The man’s wife — only aware that he has COVID-19 — has isolated herself in the couple’s lavish home in northern England.

“He thought he had the perfect alibi to carry out his affair, but hadn’t reckoned on the coronavirus meltdown,” the insider told the outlet. “The patient is just relieved he got home before flights were canceled — that would have taken some explaining. He’s in a blind panic, but more about his adultery being exposed rather than his health.”

He admitted to doctors that his affair is with a woman, but he refused to identify her, according to the report.

Italy is battling the largest coronavirus outbreak outside Asia — with 31,506 total cases and 2,503 deaths reported by Tuesday, officials announced.
