In the week to August 2, the rate of infection among 15 to 44 year olds in England was 11.9 per 100,00 people – up 35 per cent from the week ending July 5 at 8.8 per 100,000.

At the height of the pandemic, in the week to May 3, the infection rate was at 302 per 100,000 people among the over 85s, and 44.1 in the 15 to 44 age bracket.
