COVID about. Checking my notes about when I had COVID last year and it was 8 days from testing positive to testing negative. I got lucky. However, a useful part of keeping notes is that 4 days before that I noted feeling febrile and delirious. Then followed by feeling mostly better the next day so I didn't bother testing until I had a sore throat. So it was probably closer to 12 days (assuming it could have been incubating prior to symptoms). A craving for fry-ups (bacon, eggs, sausages, tomatoes, toast), increased salt sensitivity and hyperosmia. The hyperosmia persisted (luckily not unpleasantly manifested) and the salt/flavour sensitivity was like being a kid again but faded. It wasn't the worst but it wasn't good - tediously fatigue and a weird feeling. Wolfing down fry-ups with a razorblade sore throat required sucking anaesthetic lozenges while cooking. I wouldn't generalise my experience to that of other people or assume that if I got it again it'd be the same - nature has dice.
