Latest results from the REACT-1 study on COVID-19 prevalence across England – round 15 final report

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.

Speakers included:

Prof Paul Elliott, FMedSci, Director of the REACT programme, and Chair in Epidemiology and Public Health Medicine, Imperial College London

Prof Christl Donnelly, WHO Collaborating Centre for Infectious Disease Modelling, MRC Centre for Global Infectious Disease Analysis, Abdul Latif Jameel Institute for Disease and Emergency Analytics (J-IDEA), Imperial College London; and Department of Statistics, University of Oxford

This Briefing was accompanied by an SMC Roundup of Comments.
