Jimmy Fallon tests positive for COVID

The Tonight Show host, 47, took to Instagram Monday to detail his health battle, along with a photo of himself seated in a testing room.

'Hey guys, on the first day of our holiday break I tested positive for Covid,' Fallon said. 'I was vaccinated and boostered which made me lucky enough to only have mild symptoms.

'Thank you to the doctors and nurses who work so hard around the clock to get everyone vaxxed. Thank you to NBC for taking the testing protocols so seriously and doing a great job.'

Quoting the late Gary Coleman from Diff'rent Strokes, Fallon concluded in saying, 'And also thanks for putting me in the “What ‘chu talkin’ about Willis?” isolation room when they told me the news.'

Fallon told a fan who asked about his health in the comment section that he has recovered and is slated to host the show this week. He wrote, 'The positive came back on 12/18. Back at work today and feeling 100%!'

Fallon last taped an episode of The Tonight Show on December 17, which featured guests including Anthony Anderson and Adam Devine, and Carly Pearce performing. 

He also said he was 'back to 100%' in responding to Reese Witherspoon's message wishing him 'a speedy recovery.'

Fallon's case comes as a number of celebrities - such as Hugh Jackman, Whoopi Goldberg, LL Cool J and Debra Messing - have revealed they had tested positive for COVID-19 amid a spike in numbers from the omicron variant.

The omicron rates in New York City impacted NBC productions, as an outbreak among Saturday Night Live personnel led the show to tape its final episode of 2021 with no audience and a scaled down cast and crew.

The rising rates also impacted a number of Broadway productions - such as Hamilton, Ain’t Too Proud, Tina – The Tina Turner Musical and Harry Potter and the Cursed Child - which were shuttered temporarily amid the outbreak.
