A record two million people in the UK are estimated to be suffering from long COVID, the Office for National Statistics has said.
Of the two million, 1.4 million said they first had coronavirus, or suspected they had the illness, at least 12 weeks previously, while 826,000 first had it at least a year earlier.
Another 376,000 said they first had COVID-19 at least two years previously.
The figures are based on self-reported long COVID from a representative sample of people in private households in the four weeks to 1 May.
The condition is estimated to be adversely affecting the day-to-day activities of 1.4 million people - around seven in 10 of those who reported having it.
A total of 398,000 say their ability to undertake day-to-day activities has been "limited a lot", the ONS found.
Fatigue continues to be the most common symptom - experienced by 55% of those with self-reported long COVID - followed by 32% with shortness of breath, 23% with a cough and 23% with muscle ache.
