An independent study led by ZOE estimates that there could currently be as many as 1,134 active cases of COVID-19 in Herefordshire at present, based on data from 3,311 contributors across the county. This compares to official data from Public Health England that has shown over 200 cases of COVID-19 recorded in Herefordshire over the past seven days.

About the COVID Symptom Study


The COVID Symptom Study app is a not-for-profit initiative that was launched at the end of March 2020 to support vital COVID-19 research. The app was launched by health science company ZOE with scientific analysis provided by King’s College London. With over 4 million contributors globally, the Study is the world’s largest ongoing study of COVID-19 and is led by ZOE Co-Founder, Tim Spector.

By using this app you’re helping 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 Professor Tim Spector, a professor of genetic epidemiology at King’s College London and director of a scientific study of 15,000 identical and non-identical twins, which has been running for nearly three decades.
