Two I know of - a dd who went with partner to S Africa early last year, mostly for the cricket (he’s one of the Barmy Army) but dd caught something on the plane from a passenger endlessly coughing and spent the vast majority of the holiday in bed, feeling really rough. Continued to feel rough and very tired for a long time.
Two, a BiL, not in the best of health anyway, was ill in the immediate aftermath of a knee op early last year - was kept in hospital much longer than usual and took a long time to feel anything like normal again.
At a recent appt. his consultant said that in hindsight, he’d almost certainly had COVID.
