1. Main points
An estimated 1.8 million people living in private households in the UK (2.8% of the population) were experiencing self-reported long COVID (symptoms persisting for more than four weeks after the first suspected coronavirus (COVID-19) infection that were not explained by something else) as of 3 April 2022 (see Figure 1).
Of people with self-reported long COVID, 382,000 (21%) first had (or suspected they had) COVID-19 less than 12 weeks previously, 1.3 million people (73%) at least 12 weeks previously, 791,000 (44%) at least one year previously and 235,000 (13%) at least two years previously.
Of people with self-reported long COVID, 556,000 (31%) first had (or suspected they had) COVID-19 before Alpha became the main variant; this figure was 249,000 (14%) in the Alpha period, 446,000 (25%) in the Delta period, and 438,000 (24%) in the Omicron period.
Long COVID symptoms adversely affected the day-to-day activities of 1.2 million people (67% of those with self-reported long COVID), with 346,000 (19%) reporting that their ability to undertake their day-to-day activities had been "limited a lot".
Fatigue continued to be the most common symptom reported as part of individuals' experience of long COVID (51% of those with self-reported long COVID), followed by shortness of breath (33%), loss of sense of smell (26%), and difficulty concentrating (23%).
As a proportion of the UK population, prevalence of self-reported long COVID was greatest in people aged 35 to 49 years, females, people living in more deprived areas, those working in social care, teaching and education or health care, and those with another activity-limiting health condition or disability.
The estimates presented in this analysis relate to self-reported long COVID, as experienced by study participants who responded to a representative survey, rather than clinically diagnosed ongoing symptomatic COVID-19 or post-COVID-19 syndrome in the full population.

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 four weeks after you first had COVID-19, that are not explained by something else?"
Estimates include people living in private households, and do not include those in communal establishments such as halls of residence, prisons, schools, hospitals, or care homes.
Estimates for the four-week period 6 February to 6 March 2021 are also available in our previous prevalence of ongoing symptoms following coronavirus release.

If you are worried about new or ongoing symptoms four or more weeks after having COVID-19, there are resources available to help. See the NHS webpage on the long-term effects of coronavirus and the NHS Your COVID Recovery website, which can help you to understand what has happened and what you might expect as part of your recovery. The time it takes to recover from COVID-19 is different for everyone, and the length of your recovery is not necessarily related to the severity of your initial illness or whether you were in hospital.
This is analysis of new, recently collected data, and our understanding of it and its quality will improve over time. Long COVID is an emerging phenomenon that is not yet fully understood. These are Experimental Statistics, which are statistics that are in the testing phase and not yet fully developed.

3. Measuring the data
This analysis was based on 362,771 responses to the Coronavirus (COVID-19) Infection Survey (CIS) collected over the four-week period ending 3 April 2022, weighted to represent people aged two years and over living in private households in the UK. Self-reported long COVID was defined as symptoms persisting for more than four weeks after the first suspected COVID-19 infection that were not explained by something else. Parents and carers answered survey questions on behalf of children aged under 12 years.
Date of first (suspected) COVID-19 infection was taken to be the earliest of:
- date of first positive test for COVID-19 during study follow-up
- date of first self-reported positive test for COVID-19 outside of study follow-up
- date of first suspected COVID-19 infection, as reported by the participant
Those with an unknown date of first (suspected) COVID-19 infection are in the estimates for "any duration" but not in duration specific estimates.
Of the 10,431 participants who described themselves as having long COVID in the latest four-week period, 7,464 (72%) had previously ever received a positive test (swabs for COVID-19 infection or blood test for COVID-19 antibodies), either during CIS follow-up visits or outside of the study. The remaining 2,967 (28%) had never received or reported a positive COVID-19 test. This this percentage was highest in participants who first had (or suspected they had) COVID-19 at least two years previously (39%), which was before the introduction of national testing programmes.
The definition of self-reported long COVID in this release is consistent with that used for Approach 3 in our technical article on the prevalence of post-acute symptoms 4 or 12 weeks after COVID-19 infection. The estimates in this release are expressed out of everyone in the population; in contrast, the denominator for the estimates in our technical article is the number of infected people in the study sample. A further difference is that this analysis is based on confirmed and suspected COVID-19 infections, whereas the estimates in the technical article include only laboratory-confirmed cases.
The focus of this analysis is the population prevalence of self-reported long COVID. For data on the impact of long COVID, see results from the Opinions and Lifestyle Survey and the Schools Infection Survey.
Various breakdowns were changed in the last prevalence of ongoing symptoms following coronavirus infection bulletin. These breakdowns have been continued in this publication. Notably, the reported breakdowns by variant period represent the percentage of people with self-reported long COVID in the current four-week reference period who were first infected (or suspected they were infected) during each of the variant periods. They do not provide estimates of the likelihood of developing long COVID if infected with each variant. Estimates of the likelihood of developing long COVID symptoms after infection compatible with the Delta or Omicron variants are provided in our bulletin Self-reported long COVID after infection with the Omicron variant.
The strengths and limitations of this analysis are described in a previous prevalence of ongoing symptoms following coronavirus infection release. The survey questions relating to self-reported long COVID can be found in Section F of the enrolment and Section D of the follow-up CIS questionnaires. See Tables 2a to 2f of the technical CIS dataset accompanying the latest Coronavirus (COVID-19) Infection Survey statistical bulletin for survey response rates for survey response rates.Nôl i'r tabl cynnwys
