The REACT-1 team from Imperial College London has now completed round 10 of their study looking at virus prevalence across England.
This batch of data includes 140,844 swab tests carried out across England between 11 and 30 March 2021. The study gives an estimate of prevalence of COVID-19 and of R, and has data on different demographic 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.
