Babak Khosrowshahi was taken to hospital with coronavirus at 4am on 22 March - a day many people in the UK had spent on FaceTime talking to their mums on Mother's Day. The 61-year-old was finally discharged 86 days later.
More than 40,000 died of Covid-19 while Babak was in hospital. He says he owes his life to the NHS.
Here is his story of surviving coronavirus.
To be honest I haven't got a clue where I got Covid-19 from. I'm still thinking back and it's pointless. I was very careful. I was washing my hands, I never used public transport and always used my car.
But I do know where it all started. It was a Friday, Friday the 13th actually. My partner was coming to see me and I had this feeling that something wasn't quite right. Looking back it must have been the fever but because my body temperature was so low it didn't dawn on me, I just had a feeling.
When my partner came over I was inherently trying to keep away from her because Covid was on my mind. The next day I realised this feeling wasn't going away and so I found an old thermometer and took my temperature, It was 38.5C. I saw that and thought "this is happening and it's something serious".
I called 111 and they said wait seven days before calling 999. In that time my temperature stayed high and my health was deteriorating. I was finding it difficult to go from room-to-room. Just getting up to get something to eat was very tough, it was pretty grim and eventually a friend called 999 for me.
