The COVIDENCE UK Research Study has been developed in response to the outbreak of coronavirus disease (COVID-19). We are asking people aged 16 years or older, from all parts of the UK and from all walks of life, to sign up and fill in an online questionnaire with details about their lifestyle and health.

Participants will then be contacted every month to check if they have developed any symptoms of coronavirus disease, and to ask some follow-up questions about participants' more general health and social circumstances.

The data we collect will be analysed in order to:

  • advance understanding of risk factors for coronavirus disease among UK adults
  • find out how quickly people recover from coronavirus disease and whether there are any long-term complications of this illness
  • evaluate the impact of coronavirus disease on the physical, mental and economic wellbeing of the UK population
  • establish a platform for future research on coronavirus disease in the UK.

To date, we have over 18,900 participants across the UK and have been featured in BBC News, Daily Express, The Mirror, The Lancet, The BMJ and more. To find out more information please visit our website and YouTube page for updates on our progress:
