REACT-1 study of coronavirus transmission: November 2020 interim results
Data from current period (13th-24th November 2020), based on a random sample of the population, suggest a 30% proportionate reduction in prevalence overall and an R number of 0.71 (0.54, 0.90). The trends were driven mainly by reductions in higher-prevalence northern regions.
