The REACT-1 team from Imperial College London has now completed round 18 of their study.
This batch of data includes around 95,000 swabs collected between 8 February and 1 March 2022.
The study will look at prevalence of infection across different regions and demographics in England, and will provide an estimate of R. It will also provide sequencing information and prevalence of variants.
Please note this data will be a preprint, so it is early work that has not yet been through peer-review and is not published in a journal.
