This briefing covered the latest interim data from the largest community coronavirus testing programme, REACT. This batch of data is an interim report from round 9 and includes 85,000 swab tests carried out across England between 6 and 13 February 2021. The study gives an estimate of prevalence of COVID-19 and of R, and has data on different age groups and regions of England.
Please note this data is a preprint, so it is early work that has not yet been through peer-review and is not published in a journal.
