The UK reproductive number, or R value, of coronavirus transmission is closer to 1.
Data released on Friday by the Government Office for Science and the Scientific Advisory Group for Emergency (Sage) show that the estimate for R for the whole of the UK is between 1 and 1.1.
Last week the R number was between 1 and 1.2.
R stands for the average number of people that each Covid-19 positive person will be infected.
When the number is above 1, a breakout can grow exponentially.
An R number between 1 and 1.1 means that on average every 10 infected people will infect between 10 and 11 other people.
The estimates for R and the growth rate are provided by 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 0% and plus 2% for the whole of the UK.
This means that the number of new infections increases by 0% to 2% every day.
Estimates for R and growth rates are shown as a range, and experts believe that the true values are within that range.
Sage also said the numbers released on Friday more accurately reflect the average situation over the past few weeks than the current situation.
They said, “Sage is not confident that R is currently above 1 in England, although this will not be fully reflected in the data streams our models are based on.
“These estimates are based on the most recent data available as of November 17th and do not yet accurately reflect the interventions launched in England on November 5th.”
