• [Pre-print, not peer reviewed] Preliminary data from SwissCovid, the first Exposure Notification-based contact tracing app launched on June 25, shows that voluntary digital contact tracing has asimilar effectiveness for identifying infected partners of COVID-19 index cases as classic contacttracing, provided that both the index case and the exposed contacts use the app. The authorsconclude that the app can be used as a complementary tool for controlling the spread of SARS-CoV-2 within and across country borders.
