Estimates suggest that around 1.3 million people in the UK (around one in 50) are likely to be suffering from long Covid.
The numbers include over half a million people who either first became infected with Covid, or suspected they had the virus, at least one year ago.
Data from the Office for National Statistics are based on self-reported long Covid and includes a representative sample of people in private households.
The NHS website describes long Covid as "symptoms that last weeks or months after the infection has gone".
While many people usually feel better in a few days or weeks with a full recovery within 12 weeks, some people can experience symptoms for a much longer time.
In the four weeks approaching December 6, responses were collected by the ONS - this means the data excludes the surge in cases coming from the spread of the Omicron variant because it came afterwards.
Among the 1.3 million people with long Covid, 70 per cent (892,000) first had or suspected they had Covid-19 at least 12 weeks previously.
Meanwhile, 40 per cent (506,000) first had the virus at least a year before the data was collected.
Around 809,000 people are estimated to have their day-to-day activities severely affected by long Covid - this is close to two-thirds of people with self-reported long Covid.
