UK starts testing coronavirus contact tracing app

5 May, 2020

The UK government launched its first test of a coronavirus contact tracing app Monday on a small island off the south coast of England.

Using bluetooth technology, the app will alert users if they have been near someone who has tested positive for the virus. The app, which was developed by the digital technology unit of the National Health Service (NHS), will also upload information to a central database to help public health experts study the behavior of the virus.
