Piers Morgan has admitted that having Covid was the "roughest he's ever felt".
The former Good Morning Britain presenter says he caught coronavirus after attending the Euro 2020 final between Italy and England at Wembley Stadium.
Crowds of fans who didn't have tickets swarmed the venue during the match, which was won by Italy.
Piers, who was fully vaccinated before catching the virus, started feeling symptoms two days after the final, which included a fever and body aches.
He said: "This is definitely the roughest I've felt from any illness in my adult life, BUT, as I slowly come out the other side, coughing and spluttering."
"I'm still here – unlike so many millions around the world who've lost their lives to Covid in this pandemic.
"For that, I owe a heartfelt debt of thanks to the brilliant scientists up in Oxford who created the Astra-Zeneca vaccine with such astonishing speed."
Piers said he believes he caught the Delta Covid variant a fortnight ago at the final.
"My confidence that the event would be 'covid safe' had disintegrated," Piers said. "It was turning into an unregulated free-for-all."
Just a few days after the game, he began experience raging fever, chills and violent coughing and sneezing fits.
He also suffered from cold sweats and "strange aches".
Piers took a lateral flow test that came back positive and a PCR test, which confirmed the result.
He has now recovered from his symptoms, but he says his voice is now much lower.
He told the Mail on Sunday: "My voice now sounds like Barry White, though I couldn't feel less like a Walrus of Love."
Piers had shared pictures of himself in the crowd watching the game with his sons and photos of him in the stadium with comedian Jack Whitehall.

Piers has had two doses of the AstraZeneca vaccine.
The AstraZeneca vaccine has been found to be around 70% effective at stopping transmission of Covid and it is between 60-73% effective at stopping symptoms.
The jab is also around 80% effective at stopping severe illness from Covid.
It comes after Piers hit out at people who refuse to get the vaccine, calling "deluded ignorant morons" earlier this week.
Piers tweeted: "People have the right to not get vaccinated against covid.
"Just as I have the right to think they're selfish, deluded ignorant morons who will keep this pandemic going much longer than it should."
