Can't answer the questions but, when my OH had it, he started to feel unwell on the Sunday morning, by the afternoon, he felt worse, so I told him to go to bed, he did, next day, full blown, flu symptoms. Like he'd caught the flu bug, twice over. If you see what I mean.
Now, he must've had that inside, for at least a few days, (?) we'd shared the same bed, ok, not always together, but in the same sheets etc, and I didn't catch it.......OR, I HAVE caught it and showed no symptoms. 🤷♀️
He was like that, for about a week, flu symptoms, only worse than flu, the sweating was something else, and for most of it, he slept. I woke him to drink water, or else he'd have been asleep and dehydrated. He was delirious, sometimes talking a load rubbish. Then after about a week or so, he sat up, said he felt different somehow, and we thought great, he's beat it, only to go down hill the next day with the start of pneumonia. xx
