Hundreds of thousands of people across the UK are experiencing long Covid lasting a year or more, new figures suggest.
An estimated 385,000 people in private households in the UK have experienced long Covid lasting for at least a year, up from 376,000 a month ago.
The figures, from the Office for National Statistics (ONS), also suggest 962,000 people in the UK were experiencing long Covid in the four weeks to June 6, defined as symptoms persisting for more than four weeks after their first suspected coronavirus infection.

The ONS estimated that long Covid was negatively affecting the ability of 634,000 people – around two-thirds of those with self-reported long Covid – to carry out daily activities.
Of these, 178,000 said their ability to undertake day-to-day activities had been “limited a lot”.
Fatigue was the most common symptom affecting people with long Covid (535,000 people), followed by shortness of breath (397,000), muscle ache (309,000) and difficulty concentrating (295,000).
Those aged 35 to 69 were most likely to report the condition, as were women and those working in the NHS, social care or living in deprived areas.
It comes after a study found that only a small proportion of cases of long Covid are being recorded by GPs.
There is no agreed definition of long Covid, but symptoms include fatigue, muscle pains and ongoing issues similar to those seen in the initial infection.
Previous research has estimated that as many as two million people in England could be suffering ongoing symptoms after a Covid-19 infection.
Experts from Oxford University and the London School of Hygiene and Tropical Medicine said their study raised questions about how long Covid is diagnosed, recorded and managed in the NHS.
They found that only 23,273 cases were formally recorded between February 2020 and April 2021 at GP practices in England.
More than a quarter of practices (26.7%) had never logged a case, according to the article in the British Journal of General Practice.
Academics suggested there could be a number of reasons for the findings, including patients not yet seeing a GP about symptoms, doctors having different diagnostic thresholds or criteria, and issues around how the diagnosis is recorded in GP computer systems.
