An R number between 0.8 and 1.1 means that for every 10 people infected, they will on average infect between 8 and 11 other people. Last week the range was 1.1 to 1.5.

The daily growth of infections was estimated at between -6% to +1%, a big fall of the previous weeks range of +1% to +5%. The UKHSA said the figures represented the situation in England 2-3 weeks ago.
