The reproduction rate, or R-value, of coronavirus transmission in the UK is closer to 1.
Data released Friday by the Government Office for Science and the Scientific Advisory Group for Emergency (Sage) shows that the estimate for R for the entire UK is between 1 and 1.1.
Last week the R number was between 1 and 1.2.
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 1 and 1.1 means that on average every 10 infected people infects between 10 and 11 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 0% and plus 2% for the UK as a whole.
It means that the number of new infections is increasing by 0% to 2% 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.
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 on which our models are based.
“These estimates are based on the most recent data available up to November 17th and do not yet accurately reflect the interventions introduced in England on November 5th.”
