I know a couple of people who've had it, in their late 20s mid 30s and they say it's been similar to the worst flu they've ever had multiplied by 2. So I guess it's not something to lightly mess with if you can avoid it.
It's like a cold that goes around, we are all going to get it, there is a cold going around at the moment, the Covid isn't spreading but a cold is, hmmmmm, obviously we have Herd.
I had it, milder than a mild cold, barely new I had it, known 40+ people who've had it, nobody bad only 2 or 3 had the annoying bad cough even.
They either got unlucky, or they'd watched the TV and mainly thought it was worse cause so scared of it, 1 of my mates thought she was dying couldn't breathe, went over to see her, calmed her down and not that bad at all after.
