Both TraceTogether and SafeEntry are essential for effective contact tracing. SafeEntry provides a record of venues visited by COVID-19 cases, while TraceTogether helps to identify the close contacts who were in close proximity with COVID-19 cases.
Together, they enable contact tracers to quickly identify individuals who are at risk of contracting COVID-19, isolate them and break the paths of transmission as early as possible. As we resume more economic and social activities, transiting to TT-only SE will ensure that contact tracing is strengthened.
