Latest results from the REACT-1 study on COVID-19 prevalence across England

The REACT-1 team from Imperial College London has now completed round 19 of their study – this is the final round of REACT-1 surveillance for COVID-19 prevalence.

This batch of data includes samples from over 100,000 people collected between 8 and 31 March 2022.

The study presents data on infection prevalence across the country and in different age groups; sequencing; and an estimate of R and growth rate.

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, Jameel Institute, Imperial College London; and Department of Statistics, University of Oxford
