My symptoms have been as follows (age 50, fit & healthy, double jabbed 6m ago):
Days 1-3 tired/lack of energy, sleeping a lot, increasing over the 3 days
Days 4-6 bad cold/flu-type symptoms. 1 very bad with night chills, sweating, verging on hallucinating. Runny nose but blocked at the same time, sinus pressure, blocked ears, felt pretty awful but just about functioning.
Days 5-7 slightly better symptoms but lost sense of smell (and most of taste). Still very tired, hard to concentrate on eg working from home (mostly didn’t).
Days 8-10 energy slowly returning, enough to put a wash on, tidy up a bit, change bed. Still coughing a bit.
On day 10 today - had a tiny glimmer of smell this morning, hoping it returns soon
. Taste is sort of there - I can tell between sweet/salt/bitter/sour whereas DH lost everything (also double-jabbed).
16yo DD was first to test positive. She had very bad fatigue, headaches, eye aches, coughing, sweats, loss of smell and taste. She is mega fit and it wiped her out for over a week. 13yo DD2 caught it last in the household and has had mild symptoms: headaches and eye aches (less than a week so far).
