I hope they roll out antibody tests soon. I was very ill and GP over phone thought I had covid but I was never offered the test so I don't know. It would be great to have immunity, even if only for a year.
I do hope you get better soon. One of my internet acquaintances caught the virus at the beginning of March, probably on public transport (Tube). She's on the mend, but she was really ill for 6 weeks (her immune system got a little overexcited) and she nearly ended up being hospitalised.
She says it's far, far worse than the flu, which she's had a couple of times. She also had it in two 'waves', i.e. she thought that she was pulling through, and then she became sick again, and this time it was far worse and she really thought for a while that she was going to end up in the ICU. Fortunately one of her relatives who is a nurse, and had also caught the virus but was completely symptom free, volunteered to come and nurse her... so she actually gets more attention than she would in hospital. She's in her mid 30s, no underlying condition, normal BMI, healthy diet... She's a redhead though, and quite prone to whingeing!
Several of her relatives and friends work as nurses and they're exhausted. I don't think any of them have caught the virus but some of their colleagues did, a few of them symptomatic, and a handful got quite ill. It seems that most people are fine but for the few who get very ill, the outcome is much more often fatal than with the flu... and people need a lot more time to recover, even if they have not been curarised!
