My nephew has had a confirmed case, he works for DWP and a lot in his office went down with it last week, it seemed to leave the older staff alone but a high percentage of the under 25’s got it.
It started last weekend and was rough and in bed for a few days, but not feeling to bad by Thursday or Friday and back to work today.
One guy who started with it at around the same time has ended up in hospital with a really nasty chest infection, he is a pretty fit guy and looks after himself by all accounts, while my nephew doesn’t
so guess it’s unknown until you get it as to how much it will affect you.
