Number of people with long COVID in the UK in 2022, by symptoms

The source adds "Estimates relate to self-reported long COVID, as experienced by study participants, rather than clinically diagnosed ongoing symptomatic COVID-19 or post COVID-19 syndrome. Study participants were asked to respond to the following questions: "Would you describe yourself as having 'long COVID', that is, you are still experiencing symptoms more than 4 weeks after you first had COVID-19, that are not explained by something else?" and, if so: "Does this reduce your ability to carry-out day-to-day activities compared with the time before you had COVID-19?" and "Have you had any of the following symptoms as part of your experience of long COVID? Please include any pre-existing symptoms which long COVID has made worse."
"These results should be interpreted with caution because it is not known how many people would have experienced these symptoms even if they had not been infected with coronavirus. Data on 21 individual symptoms were collected only from study participants who reported experiencing long COVID, so we were unable to compare symptom prevalence in these people to that in the general population."
