A team at Oxford University is sharing an epidemiological model to help configure a contact tracing app for coronavirus. The model offers several safe configurations to introduce an app and a framework to optimise the app after it is released.

The simulations confirm that if around half the total population use the app, alongside other interventions, it has the potential to stop the epidemic and help to keep countries out of lockdown. These research efforts are supporting several European projects including the UK’s national programme led by NHSX, a joint unit comprised of teams from NHS England and the Department of Health & Social Care.
