The R number – a key measure of how much coronavirus is spreading – has risen slightly in England to reach between 0.8 and 1.0.

Last week, the R number in England was between 0.8 and 0.9.

This week's figures are the latest since England's lockdown was eased to allow people to visit pubs, bars and restaurants.

The growth rate of COVID-19 infections in England has also risen, from -5% to -2% per day last week, to -4% to -1% per day this week.

The R number for the whole of the UK remains between 0.7 and 0.9, according to figures published by the government's Scientific Advisory Group for Emergencies (SAGE) on Friday.


Meanwhile, the growth rate of infections across the whole UK is estimated to have fallen.

Last week, for the whole of the UK, it stood at -6% and -0% per day, and is now at -5% and -2% per day.

The growth rate reflects how quickly the number of infections are changing day by day.

It is an approximation of the change in the number of infections each day.

If the growth rate is greater than zero, then the disease will grow, and if the growth rate is less than zero then the disease will shrink.

Special report: The NHS – catastrophe brings change

The size of the growth rate indicates the speed of change.

A growth rate of -4% indicates the epidemic is shrinking faster than a growth rate of -1%.

If the R value is one, then it means each infected person will on average pass COVID-19 on to one other.

If it is above one, it means the number of COVID-19 cases will increase exponentially.

However, if it is below one, the disease will eventually peter out as not enough new people are being infected to sustain the outbreak.

The R number is estimated to be between 0.7 and 1.1 in the South West – the upper limit rising slightly from 1 last week.

The number could be as high as one in every other English region apRead More – Source
