R number edges down slightly to a maximum of 1.1

Written by on 20 November 2020

The UK’s reproduction number has fallen slightly to a maximum of 1.1 from a maximum of 1.2, according to new figures.

The figure has been confirmed by the Scientific Advisory Group for Emergencies (SAGE), which advises the government on its response to the pandemic.

Scientists have estimated the reproduction number, known as R, is now between 1.0 and 1.1.

R represents the average number of people each COVID-19 positive person goes on to infect.

This means on average every 10 people with coronavirus will infect between 10 and 11 others.

The reproduction number was between 1.0 and 1.2 last week.

The R number is one of the many indicators scientists use to determine how quickly COVID-19 is spreading.

When the figure is above 1, an outbreak can grow exponentially.
