R number for Surrey slightly decreases but remains joint highest in the country

The R number for Surrey and the South East is once again the joint-highest in the country,

According to the latest Government figures, published on Friday (November 20), the R number in the South East has remained at between 1.2 and 1.4.

That figure is higher than the rate in both the North West, the North East and Yorkshire regions, the data shows, with only the South West having as high an R number.

The R number represents the number of people an infected person passes the virus on to, and anything above 1 means the epidemic is growing.

If the value is below 1, the spread of the virus will eventually decline as not enough new people are being infected to sustain the outbreak.

The growth rate for the region, which measures how quickly the number of coronavirus infections changes day by day, has decreased slightly to between +1 and +4. It measured between +3 and +6 seven days ago.

The R number for the UK has dropped to measure between 1.0 and 1.1, compared to measuring between 1.0 and 1.2 the previous week. The UK growth rate has also decreased slightly, from a range of +1 per cent to +3 per cent to +0 and +2.

The figures come as cases in Surrey are continuing to rise in the second lockdown; 151 new cases were recorded in the latest 24-hour period.

Elmbridge and Spelthorne both saw the most new cases with 22 each, while Runnymede was next with 21. There have now been 14,510 infections in Surrey since the start of the pandemic.

How does every region compare?

Every week, SurreyLive has been providing a full breakdown of the R number and, in brackets alongside, the growth rate percentage for each region in the country.

The values are shown as a range, as seen below. The most likely true values are somewhere towards the middle of this range, according to the Government.

UK: 1.0 – 1.1 (0 to +2)

England: 1.0-1.1 (0 to +2)

East of England: 1.0-1.3 (+1 to +4)

London: 1.0-1.2 (0 to +3)

Midlands: 1.0-1.2 (+1 to +3)

North East and Yorkshire: 1.0-1.1 (0 to +2)

North West: 0.8-1.0 (-3 to 0)

South East: 1.1-1.3 (+1 to +4) previously 1.2 – 1.4 (+3 to +6)

South West: 1.0-1.3 +1 to +4

What does the growth rate mean?

The growth rate reflects how quickly the number of infections is changing day by day. It is an estimation of the percentage change in the number of infections each day.

If the growth rate is greater than zero (+ positive), then the epidemic is growing. If the growth rate is less than zero (- negative), then the epidemic is shrinking.

The size of the growth rate indicates the speed of change. A growth rate of +5 per cent indicates the epidemic is growing faster than a growth rate of +1 per cent. Likewise, a growth rate of -4 per cent indicates the epidemic is shrinking faster than a growth rate of -1 per cent.
