More than one million people in the UK are living with long Covid, the first national survey of the phenomenon by the Office for National Statistics found.
UK Secretary of State for Health Matt Hancock said this week he was "very worried" about the impact, with almost one in seven people who test positive for the virus still suffering symptoms three months later.
An estimated 697,000 first had Covid-19, or suspected they had it, at least 12 weeks previously, while 70,000 first had or suspected they had the virus or suspected at least one year ago. Long Covid was estimated to be adversely affecting the day-to-day activities of 674,000 people, with 196,000 reporting that their ability to undertake day-to-day activities had been limited.
