Professor Christophe Fraser from the Big Data Institute, Nuffield Department of Medicine, a lead author on the Science paper explains, “We need a mobile contact tracing app to urgently support health services to control coronavirus transmission, target interventions and keep people safe". The project is co-led by Dr David Bonsall, who explains “The mobile app concept we’ve mathematically modelled is simple and doesn’t need to track your location; it uses a low-energy version of Bluetooth to log a memory of all the app users with whom you have come into close proximity over the last few days. If you then become infected, these people are alerted instantly and anonymously, and advised to go home and self-isolate".
