Sounds like Rich Stokoe's experience. Well, the first bit. Not sure if he's had it a second time, but I do remember him talking about the second infection long-covid "cure". He's probably running around Newcastle licking people/things trying to get infected again.
So far both Rebecca and I have avoided it, but my sister in-law Sarah and her family have recently been hit with it and Rebecca and Sarah work together in the same school, so it's only time before it turns up here.
