Real-time Assessment of Community Transmission (REACT) Study

About the REACT programme

The REACT Cohort is a major national resource for researchers to study the longer-term impacts of the pandemic and other factors on health and wellbeing. Launched in April 2020, the REACT programme began as one of the world’s largest and most comprehensive coronavirus monitoring studies.  

REACT Cohort is now made up of over 3 million people who have consented to follow-up by providing permission for us to contact them future research and/or to link to their health data. 

We are grateful to all of the participants who have taken part and consented to follow up, their input is essential to the success of the current and future health research carried out as part of REACT.
