@becsbuddy, here is the link to more information about the ZOE COVID Study that @strongevergreen refers to
- ZOE COVID Study https://covid.joinzoe.com/about

It is an app gathering information from the general public to predict who has the virus and so track COVID infections originally in the UK and now other countries. People are asked to download the app and report information daily. Daily reporting data are used to generate new scientific understanding of the different symptoms the virus causes in different people and more.

The News and Research section (https://covid.joinzoe.com/blog) on the website shares more about the research, webinars, and academic papers that are being produced entirely because of the contributions by the public.

If anyone is interested in taking part in the global tracking research, I recommend starting with the FAQ section https://covid.joinzoe.com/faq and being informed about the use of data.
