When it comes to cheating in a marriage, things are always going to be messy.

But when you add a global pandemic into the mix, things suddenly become even more complicated.

One man is currently panicking that his wife is going to discover his infidelity after he tested positive for coronavirus following a recent trip overseas.

His unsuspecting wife believes he was away in the UK on business when he caught the virus, but in reality, he was on a secret break in Italy with his mistress, reports The Sun.

The unnamed man said to be in his late 30s, has revealed to public health coordinators in the north of England the truth about how he picked up the bug.

The man is described as "well-heeled and with a high-flying job".

He is said to have told doctors that he was with another woman but has refused to name her.

Due to his condition, his wife is currently self-isolating at their lavish home.

Speaking to The Sun, a source said: "This patient is the talk of public health officials.

"His case would be funny if it wasn't quite so serious.

"Despite his infection, he is expected to survive the outbreak, unlike his extra-marital relationship.

"He thought he had the perfect alibi to carry out his affair but hadn't reckoned on the coronavirus meltdown. The patient is just relieved he got home before flights were cancelled - that would have taken some explaining."

They added: "He's in a blind panic, but more about his adultery being exposed rather than his health."
