When to self-isolate
Self-isolate straight away and get a PCR test (a test that is sent to the lab) on GOV.UK as soon as possible if you have any of these 3 symptoms of COVID-19, even if they are mild:
- a high temperature
- a new, continuous cough
- a loss or change to your sense of smell or taste
You should also self-isolate straight away if:
- you’ve tested positive for COVID-19 – this means you have the virus
- someone you live with has symptoms or tested positive (unless you are not required to self-isolate – check below if this applies to you)
- you’ve been told to self-isolate following contact with someone who tested positive – find out what to do if you’re told to self-isolate by NHS Test and Trace or the NHS COVID-19 app
When you do not need to self-isolate
If someone you live with has symptoms of COVID-19, or has tested positive for COVID-19, you will not need to self-isolate if any of the following apply:
- you’re fully vaccinated – this means 14 days have passed since your final dose of a COVID-19 vaccine given by the NHS
- you’re under 18 years, 6 months old
- you’re taking part or have taken part in a COVID-19 vaccine trial
- you’re not able to get vaccinated for medical reasons
Even if you do not have symptoms, you should still:
- get a PCR test on GOV.UK to check if you have COVID-19
- follow advice on how to avoid catching and spreading COVID-19
- consider limiting contact with people who are at higher risk from COVID-19
