The NHS COVID-19 app is part of a large-scale, combined testing, contact tracing and outbreak management programme across England, called NHS Test and Trace.

The sooner we can work out which people are at risk of getting coronavirus (COVID-19), and, if necessary, ask them to self-isolate, the more effectively we can slow down the spread of the virus and save lives.

The success of the service relies on everyone playing their part and doing the right thing. We’ll need everyone to be aware, report symptoms to the NHS, and self-isolate if asked to do so.

Similar testing and tracing programmes are being used successfully in other countries to help control the spread of coronavirus, so life can begin to get back to normal.

It will help us to fight both this virus and future outbreaks, if needed. Find out more about NHS Test and Trace.
