About this research
The COVID-19 Symptom Study app has been developed by health science company ZOE and it is endorsed by the Welsh Government, NHS Wales, the Scottish Government and NHS Scotland. 4,079,804 participants have downloaded the app and are using it to regularly report on their health, making it the largest public science project of its kind anywhere in the world. App data is being analysed in collaboration with King's College London researchers.
By using this app you're helping the NHS and contributing to advance vital research on COVID-19. By combining your reports with software algorithms, we are able to predict who has the virus and so track COVID infections across the UK and now other countries (see COVID Data). Your daily reporting is also being used to generate new scientific understanding of the very different symptoms the virus causes in different people. We are also studying the way that risks vary between individuals because of their own personal characteristics. Visit the News and Research section to read about the research, listen to webinars, and read the academic papers that are being produced entirely because of your contributions.
This research is led by Dr Tim Spector, professor of genetic epidemiology at King’s College London and director of TwinsUK a scientific study of 15,000 identical and non-identical twins, which has been running for nearly three decades.
