Seven in 10 deaths of working-age adults involving coronavirus between March 9 and June 30 were likely to be the result of an infection acquired before lockdown, new figures show.
There were 5,330 deaths involving Covid-19 of 20-64-year-olds in England and Wales during this period, the Office for National Statistics (ONS) said.
Of these, 72%, or 3,839 deaths, occurred on or before April 25 and are considered likely to be as a result of an infection acquired before lockdown.
The ONS assumption is based on evidence that the maximum time from infection to symptom onset is 14 days, and there are around 20 days on average from symptom onset to death.
According to the Department of Health and Social Care, the number of confirmed UK cases has passed 398,625, while the total number of deaths is 41,788.
