Update on my dad, in case anyone's wondering...
For a few days it was really close whether they'd put him in a medical coma or not (50% survival rate there). Thankfully, he's been improving lately - it's still soon but he seems to have turned a corner about a week ago. They've been reducing his oxygen and his meds, he's engaged with the world around him again, organizing stuff for everyone from the hospital bed which is a bit annoying but really just a huge relief
Still can't go without oxygen for long (twenty minutes at most) but he seems to be recovering, knocking on wood here.
(Our GP sent him and two women to the hospital with COVID the same day, apparently the two women are dead. Still makes me dizzy to even think about it.)
The rest of my family has either recovered by now or are doing reasonably well, including my grandmother and my grandfather.
