Fatima Bridle, 35, was previously reported to be the UK’s longest-suffering covid patient when she was discharged from Southampton General Hospital in August after 141 days, including 105 on a ventilator.
Garraway, 53, revealed in July that she had been told six times by doctors that Draper would not survive, and added that his body has been left ravaged by the disease.
She said: “Of course, there’s fantastic hope that he’s still alive. The doctors do keep saying it is a miracle he’s still alive. Six times they said he’s not going to make it.
“He’s been very, very sick. The problem is, is that it’s a new disease which nobody knows, so there’s no data. So what they can say to me is, ‘It’s great that he’s here, it’s great that there are some flickers of hope’.
“His lungs are starting to recover a little bit, his kidneys are doing better, his liver is doing better. They don’t know how much better he can get. There is just nothing he can compare it with.”
And the I’m A Celebrity star recently admitted her heartbreak at not being able to see Draper on their 15th wedding anniversary on 10 September.
Garraway said: “What an extraordinary thing. I won’t be able to see him today.
“I kind of hoped I would but it hasn’t worked out that way for the visit… But maybe it would be a bit strange anyway. So it’s a tough day.”
Due to quarantine restrictions in place to limit the spread of coronavirus Garraway and her children Darcey, 14, and Billy, 11, have been limited in their contact with Draper due to coronavirus quarantine restrictions. But they are able to speak to him on FaceTime everyday.
