Covid Symptom Study Appeal

Updated: May 26




The COVID Symptom Study is a non-profit research initiative working to support the NHS, the health of the UK public and to facilitate the safe release of lockdown through science. Without further funding it cannot continue its critical work. The app is in collaboration with Twins UK, the Chronic Disease Research Foundation and health science start-up ZOE. It is the largest community-powered COVID research project in the world with 3 million contributors. Funds will support over 50 scientists, engineers, researchers and data science experts to analyse COVID-19 data being delivered to the NHS, the Scottish Government, the Welsh Government and Public Health England daily.


By funding this unique non-profit study, you are supporting efforts to save lives and help the UK get out of lockdown safely.


The COVID Symptom Study is the only app of its kind in the world to:

  • Prove that loss of smell is a major symptom of COVID, published in Nature Medicine.

  • Show how a combination of over a dozen symptoms can pose different risks.

  • Understand how blood pressure medication interacts with the virus.

  • Reveal the 12-fold higher risk to healthcare workers across regions.

  • Show that UK COVID infection rates peaked on the 1st of April with 2.1 M people.

  • Predict COVID hotspots around the country, and help redirect resources

  • Work with the UK’s largest health charities including Cancer Research UK, Versus Arthritis, Age UK and all of the 23 Royal Medical Colleges to help the country’s most vulnerable groups.

Support our healthcare system in conducting research at-scale including:

  • Researching Hormone Replacement Therapy studies to understand the role of oestrogen and COVID with NHS England;

  • Using our machine learning symptom model to support the Department of Health and Social Care to test the public nationally;

  • Identifying possible blood plasma donors to support treatment and trials of ICU patients with NHS Blood and Transplant Service.

This project is saving lives through science and will play an essential role over the next year to support our healthcare system and the wider UK community. Please help us to keep this study going through your participation and donations. The money raised will fund the team of over 50 researchers, data scientists, engineers and scientists working to support our health and the country’s future.


Funds no longer needed for this project will be used for other research grants into chronic diseases.
