When should a person end isolation after feeling ill? (Not just for COVID but for other things like the flu and the common cold as well.) There seems to be a conflict between what the Philippines government says and what the CDC says. The timeline for my symptoms: Day 0: Fever, raw throat, lower back pain, sensitive skin, eye pain (looking anywhere but straight forward hurt), bad headache. Day 1: Fever, raw throat, lower back pain, sensitive skin, eye pain, bad headache. Day 2: Headache, sensitive skin, back pain, eye pain. Day 3: Headache, eye pain. Day 4: Headache, eye pain. *Symptoms are gone by afternoon. Day 5 (today): First day I woke up without a pounding headache. No other symptoms. The CDC says: The only medicine I took was alka seltzer and Captain Morgan (which might have been the reason for the headaches the last 3 days). Still not sure if this was COVID and I probably never will but I would like to play it safe and not spread whatever this was.
