About the study

The coronavirus (COVID-19) endemic is still having a major impact across the UK. 

The COVID-19 and Respiratory Infections Survey (CRIS) aims to understand and manage COVID-19 and other respiratory infections in the long term. 

The data from the study, when combined with data from the COVID-19 Infection Survey (CIS), are important in helping us understand:

• the impact of self-reported COVID-19, long COVID and other respiratory infections on the lives of individuals, the community and on health services and how they are changing 

• potential pressures to help support the NHS and other services to prepare for future stressors, acting as an early warning system

The study is being conducted by the Office for National Statistics (ONS), the government's largest independent producer of statistics. We collect information about the UK's society and economy, which provides evidence for policy- and decision-making, and for directing resources to where they are needed most.

This study uses participants from the COVID-19 Infection Survey (CIS), which was commissioned and funded by the UK Health Security Agency (UKHSA). UKHSA is an Executive Agency sponsored by the Department of Health and Social Care (DHSC).
