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 13 and includes over 47,000 swab tests carried out across England between 24 June and 5 July. 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.
