Coronavirus cases in England doubling every eight days, study shows

Cases of coronavirus in England are doubling every seven to eight days, research has revealed in the latest figures to show a resurgence of Covid-19. The study, known as React-1, is a population surveillance study that began in May and uses swabs from about 120,000 to 160,000 randomly selected people in England across 315 local authority areas each month to track the spread of coronavirus using PCR analysis – the “have you got it now” test. “The prevalence of the virus in the population is increasing. We found evidence that it has been accelerating at the end of August and beginning of September,” said Steven Riley, professor of infectious disease dynamics at Imperial College London and a co-author of the work.
