Have received an app notification saying you've been in close contact with someone that has tested positive for COVID-19.
Have received an app alert saying you’ve recently been to a venue where there’s been an outbreak of COVID-19 and should book a test.
You can find 'Book a test' in the 'Testing for COVID-19' home screen option:

If you test positive for coronavirus, you'll be able to see your result through the app. You can then choose to share data anonymously, so that other app users who have spent time near you will get an alert to tell them that they're at risk.
These alerts will never identify you. The notification will typically come through within hours of getting your test result. Read more about who gets an alert if you test positive.
