COVID-19 Infection Survey
The COVID-19 Infection Survey (CIS) is the largest regular survey of coronavirus (COVID-19) infections and antibodies, providing vital information to help the UK's response to the pandemic. Find out all about the survey and what to expect if you are asked to take part. Given the importance of the survey, we will be continuing its vital work beyond the initial expected end date of April 2022, as part of the government's Living with COVID-19 plan. We will be introducing a more flexible approach, so you can post your samples to us, rather than having face-to-face appointments at your home.
