The Covid symptom tracker allows UK users to self-report symptoms daily in case they think they may have Covid19. It will allow a better understanding of who is at risk, in particular with a geographical dimension, by better understanding the symptoms that are linked to underlying health conditions.

The difficulty in collecting up-to-date data and information on people suffering from corona virus is one of the big challenges facing decision makers. There are not enough tests, or people to administer tests, to test every person with possible symptoms. Therefore, policy makers have an incomplete picture for every decision that they must make.

This tool, whilst not medically rigorous in its diagnostic elements, will provide data geographically distributed that will help medical professionals, modelers and policy makers by providng them with some geographical information about the distribution of the virus, as well as information about the symptoms of it.
