To help reduce the spread of coronavirus (COVID-19), there are a number of reasons why you may be advised to self-isolate.
To help reduce the spread of COVID-19, you may be advised to self-isolate if:
you have developed coronavirus symptoms
you have tested positive for coronavirus
you are over 18 unvaccinated and have been in ‘close contact’ with someone who has tested positive for coronavirus
In some cases you may need to continue to self-isolate even if you have received a negative test result.
You may need to continue to self-isolate even if you have received a negative test result if:
you have been advised by contact tracers to continue self-isolating. Read more about what do if the advice given by the app is different from that given by NHS Test and Trace or NHS Wales Test, Trace, Protect.
you are over the age of 18 and have not been fully vaccinated and have been in close contact with someone who has tested positive with coronavirus, you will need to self-isolate for 10 full days after that contact. Even if you test negative for coronavirus within this period, you need to complete 10 full days of self-isolation. This is because the incubation period of the virus means you could still develop coronavirus after receiving a negative test result, within 10 days of the contact. It is important to remember that as many as 1 in 3 people with coronavirus have no symptoms. If you have been in close contact with someone who has tested positive with coronavirus and you have been fully vaccinated or are under the age of 18 and it has been two weeks since your final dose of an approved vaccine, you will not need to self-isolate. In Wales if someone in your household has coronavirus you’ll be asked to self-isolate immediately and book a test. If the test is negative you can leave self-isolation.
