The reproduction rate, or R-value, of coronavirus transmission in the UK is now between 0.8 and 1.
The weekly update has been released by the Government Office for Science and the Scientific Advisory Group for Emergency (Sage).
Last week, the R number was between 0.9 and 1 – meaning this week is an improvement over the last.
R represents the average number of people infecting each Covid-19 positive person.
When the number is above 1, an outbreak can grow exponentially.
An R number between 0.8 and 1 means that on average every 10 infected people infects between 8 and 10 other people.
The estimates for R and growth rate are from the Scientific Pandemic Influenza Group on Modeling (SPI-M), a subgroup of Sage.
The growth rate, which estimates how quickly the number of infections changes from day to day, is between minus 3% and minus 1% for the UK as a whole.
It means that the number of new infections decreases by 1% to 3% every day.
Estimates for R and growth rates are presented as a range and the true values are likely to be within this range, according to experts.
Sage also said the figures released on Friday more accurately reflect the average situation for the past few weeks than the current situation.
