That virus sounds ... interesting. Golf_ghirl had covid but me and the boys tested -ve all the way thru and afterwards. Few days after golf_ghirl tested -ve I had a bad day. Tight chest, throwing up, raised temp, slumped over kitchen table with sweat dripping from me, unable to sit up without feeling I was going to pass out. Back to bed for a few hours and felt better for that (played golf the day after!), but I have a residual phlegmy cough for a couple of weeks now.
#2 son had similar, then my sister also took unwell and ended up in hospital for a week, suspected pneumonia (not sure if it was), definitely not covid. She's better now but there's something going around.
