One in 40 people with coronavirus has symptoms lasting at least three months, Office for National Statistics figures suggest.
In April, an ONS report put the proportion at about one in every 10. The latest, large and comprehensive analysis suggests long Covid may be less common than previously thought.
But the condition is not fully understood and still has no universally agreed definition, leading to different studies producing different figures.
However, like many other reports, the analysis suggests women, 50- to 69-year-olds and people with other long-term health conditions are the most likely to have symptoms of long Covid 12 weeks after a Covid infection.
People with high levels of virus in their body when testing positive are also more likely to have long Covid, the analysis suggests.
