The 47-year-old actor was among the first celebrities to have publicly declared that they had been diagnosed with COVID-19 and went into quarantine.
His wife, Sabrina Dhowre, was also diagnosed with coronavirus at the same time and the pair battled it together.
Now they are over it, there is a different issue to overcome which could take a lot longer than it took to rid themselves of the potentially fatal illness.
The Luther star spoke to his fans on social media and said: “We’ve passed the quarantine period but we’re a little bit stuck in limbo. We can’t get a flight back home.”
The actor continued: “We just have to sit still for a little bit. Other than that, we’re okay, and we’re so thankful for that. I think the worst of it has probably passed.
“It’s weird because I never sit still, Sabrina never sits still either and I think she’s finding it harder. She’s getting cabin fever.”
Giving an update on how they were feeling both physically and mentally, Idris said: “We’re both good mentally. Just trying to stay optimistic.
“I hope you guys are too, keeping yourselves sane and not getting too worried or panicked.
“I thought I was definitely going to see the worst of it as an asthmatic. But thankfully I came through and you can too.”
Idris then paid tribute to the frontline staff who are working hard to help those hospitalised during the global pandemic.
He gave a shoutout to “everyone who is helping other people, especially the doctors and nurses and health care people doing their thing. You lot are amazing and should be fully appreciated.”
“It’s going to be a tough time for everyone, but keep your head up basically.
“Hope you’re good. We’re going to fight this thing and everything’s going to be cool, man.”
The actor had previously revealed that he and Sabrina were in New Mexico, with his wife flying out to him despite knowing that he had symptoms of coronavirus.
She told Apple TV+ show ‘Oprah Talks COVID-19’: “As soon as I heard that Idris was potentially exposed, I mean, I was on my way anyway, I wanted to be with him.
“I think that’s an instinct as a wife. You just want to go and take care.”
Sabrina added: “We didn’t change the way we interacted. I could have made a decision to put myself maybe in a separate room or stay away and I’m sure that people are making those decisions that are tough decisions to make.
“But I made the decision to be with him and still touch him.”
Sabrina has doubted whether she actually had a symptom, saying: “I’m not. It could be similar to Idris.
“We’re in a high altitude it could be that I’m confusing seasonal allergies as maybe symptoms but I don’t feel anything that would come to what people would now expect to be a symptom of coronavirus, which is very strange.
“It might change in the coming weeks and we’ll keep everyone updated.
“But it is worrisome that we’re both sitting here, two people and everyone that we know that we’ve been in contact with, all asymptomatic. It’s a little bit worrisome.”
