Details

REACT-1 is the largest population surveillance study being undertaken in England that examines the prevalence of the virus causing COVID-19 in the general population. It uses test results and feedback from over 150,000 participants each month.

The study focuses on national, regional and local areas, as well as:

• age
• sex
• ethnicity
• socio-economic factors
• employment type
• contact with known cases
• symptoms
• other factors

The findings will provide the government with a better understanding of the virus’s transmission and the risks associated with different population subgroups throughout England. This will inform government policies to protect health and save lives.
