If you’ve been in close contact with someone who has coronavirus, including someone you live or are in a support bubble with, you’ll have to stay at home according to government guidelines. It is important to remember that as many as 1 in 3 people with coronavirus have no symptoms.
If the person who has coronavirus does not have the app, you will not get a notification when they test positive.
They may tell you themselves, or you may get a phone call from the NHS Test & Trace service, or the NHS Wales Test, Trace, Protect Contact Tracing Service. In this case, please follow the latest government advice.
