Scientific Advisory Group for Emergencies (Sage) published regional values for R in England for the first time. But experts cautioned against the use of regional R values which measure the average number of people an infected to pass the disease on to. Experts say that as the number of infections falls, regional R values become less reliable. If the R rate remains below one then the disease will slowly peter out as not enough people are being infected to sustain the virus. Last week, Public Health England and Cambridge University's MRC Biostatistics Unit published estimates of the Covid-19 R value at a regional level across England.
