Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The app, has been launched in both the UK and the US. Researchers in other countries are encouraged to obtain the required approvals from Apple and Google to make the app available in their territories.
The data from the study will reveal important information about the symptoms and progress of COVID-19 infection in different people, and why some go on to develop more severe or fatal disease while others have only mild symptoms do not.
It is also hoped that the data generated from this study will help the urgent clinical need to distinguish mild coronavirus symptoms from seasonal coughs and colds, which may be leading people to unnecessarily self-isolate when they aren't infected or inadvertently go out and spread the disease when they are.
Users download the free app COVID-19 Symptom Tracker and record information about their health on a daily basis, including temperature, tiredness and symptoms such as coughing, breathing problems or headaches.
The app is available internationally to the general population and will also be used in two large epidemiological cohorts: The TwinsUK cohort (n=15,000) and Nurses Health Study (n=280,000).
The app will allow scientists to study the spread and development of symptoms across whole populations, both in the UK and abroad, as well as detailed genetic and other studies, particularly with the twins cohort
Any data gathered from the app and study will be used strictly for public health or academic research and will not be used commercially or sold.
