LONDON, Nov. 20 (Xinhua) -- Britain's reproduction number, also known as R number, for COVID-19 has decreased to a maximum of 1.1 from a maximum of 1.2, Sky News reported on Friday.

The R number is the average number of secondary infections produced by a single infected person.

The current R number is estimated to be between 1.0 and 1.1, Sky news said, adding that the number has been confirmed by the Scientific Advisory Group for Emergencies (SAGE), which advises the British government on its response to the pandemic.

An R number between 1.0 and 1.1 means that on average every 10 people infected will infect between 10 and 11 other people, according to a guidance published by the British government.

If the R number is above one, it means the number of cases will increase exponentially.

As for the growth rate, which estimates how quickly the number of infections is changing day-by-day, it is between zero percent and plus 2 percent for Britain as a whole, according to Sky News.

That means the number of new infections is growing by zero percent to two percent every day.

The figures published on Friday more accurately represent the average situation in Britain over the past few weeks rather than the present situation, Sky News quoted SAGE as saying.

To bring life back to normal, countries such as Britain, China, Germany, Russia and the United States are racing against time to develop coronavirus vaccines. Enditem
