have been blown away by the commitment of over 4 million app users who
continue to share the state of their health daily. As the world's
largest study of the virus, the COVID Symptom Study is a key source of
information on the disease in the UK and globally.
Please continue to log your health daily as it plays a huge role in our detection of hotspots and understanding the long-term effects of COVID-19, which continues to impact hundreds of thousands of app users.
Stay safe, and thank you again for your contribution to science and the safety of our country.
