Self-isolate for 14 days if either:
- you get a text, email, or call from NHS Test and Trace telling you to self-isolate
- you get an alert from the NHS COVID-19 app telling you to self-isolate
This is because you’ve been in close contact with someone who has coronavirus and there’s a chance you might have caught it.
You need to self-isolate for 14 days because it can take 14 days for symptoms to appear.
