Stephen Colbert just can’t seem to shake his recent bout of COVID-19.

He had to take off a few days at the beginning of the month after a positive test.

However, he told the audience that he was back and “feeling fine.”

On Monday, though, it looks like all was not well for “The Late Show” host.

The show’s official Twitter account said that Colbert is not feeling well.

“Stephen is experiencing symptoms consistent with a recurrence of COVID,” they wrote.

To protect the cast and crew, Stephen will be isolating for a few additional days.

“The Late Show will not be taping new episodes until further notice,” they added.

Colbert retweeted the news, adding, “WORST. SEQUEL. EVER.”
