We recently heard from the REACT-1 scientists with interim results from round 15 of their study looking at virus prevalence across England. They now have the full set of data in for this round.
This batch of data includes swab tests from over 100,000 people, which were carried out across England between 19 October and 5 November 2021.
The findings give updated prevalence rates and an estimate of R.
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.
