Algehele, a total of 945,000 people are thought to be suffering from the syndrome in the UK
This includes 11,000 two to 11-year-olds and 23,000 12 to 16-year-olds, according to a survey from the Office for National Statistics.
Symptoms, which include fatigue and shortness of breath, are self-reported by participants and persist for more than four weeks after infection from Covid-19.
The findings come after a separate report, published earlier in the week, said that children are unlikely to suffer from long Covid.
Dr Elaine Maxwell, a scientific advisor at the National Institute for Health Research (NIHR) who was not involved in either study, said the ONS estimate is “hardly rare”.
Egter, she warned, “we need to keep looking at a range of different studies to sense make what it happening and it is far too soon to make bold statement about the prevalence and prognosis of long Covid in adults or children.”
The latest ONS estimates also suggest that 380,000 people in the UK have experienced long Covid for at least a year. The figure is based on responses collected from people in private households in the four weeks to 4 July and then extrapolated to the rest of the population.
Algehele, a total of 945,000 people are thought to be suffering from the syndrome – af van 962,000 reported in last month’s survey.
Long Covid was estimated to be adversely affecting the day-to-day activities of 611,000 mense, met 182,000 reporting that their ability to undertake day-to-day activities had been “limited a lot”, the ONS said.
Fatigue was the most common symptom reported as part of an individual’s experience of long Covid (528,000 mense), followed by shortness of breath (388,000), muscle ache (296,000) and loss of smell (285,000).
Prevalence of self-reported long Covid was greatest in people aged 35 aan 69, females, those living in the most deprived areas, those working in health or social care and those with another activity-limiting health condition or disability, the ONS found.
There is no universally agreed definition of long Covid, but it covers a broad range of symptoms such as fatigue, muscle pain and difficulty concentrating.
Separate research from King’s College London (KCL) suggested that children who catch Covid-19 and develop symptoms typically recover within a week.
The study, gepubliseer in The Lancet Child & Adolescent Health joernaal, looked at 1,734 children who tested positive for Covid-19 close to the onset of symptoms.
It found that the average illness lasted six days, with most children recovering from their symptoms within four weeks.
A minority – 77 kinders, of 4.4 per cent – continued to experience illness after a month, while fewer than 2 per cent were still struggling with symptoms beyond eight weeks.
Recent studies have varied considerably in their assessment of the scale and severity of long Covid among children, pointing to the complexities and limited understanding of the syndrome.
