The actor took to his Instagram Stories over the weekend (29-31Oct21) to confirm reports he had contracted the virus after the sci-fi epic's London launch on 18 October.
"Hi, everybody. Yeah, I got hit with COVID right after the premiere. There's a lot of people I met in England. Got a lot of aloha from people, and who knows," he said in a video. "Either way, I'm doing fine. Thank you for all your concerns and love."
Sources told The Sun last week the actor picked up the virus while filming the "Aquaman" sequel, "Aquaman and the Lost Kingdom".
In a second video, Jason shared that "COVID is going pretty good," and that he's "camped out in his house."
The actor joked that he and professional skateboarder Erik Ellington, his friend and current roommate, are "having a ball," and showed off footage of Ellington racing down a hallway on his skateboard.
Jason reprises his role as the water-loving hero in the second film in the franchise. He admitted recently that managing on the stunt-heavy movie has been a lot harder than when he was making the first film back in 2017.
"I'm getting old," he said. "I messed up my eyes. I just got something in it that kind of cut it up, and then I've got to get surgery, I have a hernia, I've got ribs out. I'm just getting beat up."
"I just kind of give it. I love my job and I get a little too excited, then the age thing, you know, I'm an ageing superhero right now."
