When do I have to self-isolate?

If you have any COVID-19 symptoms (a new continuous cough, a high temperature a loss or change to your sense of smell or taste) or wider cold or flu-like symptoms (including aches and pains, persistent headache or tiredness, runny/blocked nose, sore throat, shortness of breath), you should stay at home (self-isolate) and only leave you house to attend the test appointment.

After the test, you must continue to self-isolate until you receive a negative result. If you receive a positive test, you must stay at home (self-isolate) for 10 days from when your symptoms started.

Contact tracers will get in touch with all identified close contacts and provide advice according to their circumstances. This will include the offer of a PCR test and advice around self-isolation requirements. If a person is identified as a contact, they will not be required to self-isolate if they have been fully vaccinated or are under 18. However there may be certain circumstances, such as if a new variant of concern were circulating, where fully vaccinated and under 18s contacts may be required by Test, Trace, Protect to self-isolate. You should always self-isolate if asked to do so by a contact tracer This is set out in the contact tracing guidance (opens in new tab). A positive test will also result in a person being contacted by a contact tracer on behalf of the NHS Wales Test, Trace, Protect service.

If a person receives a negative test they no longer need to stay at home (self-isolate).
