When to self-isolate
Self-isolate immediately if:
- you have any symptoms of COVID-19 (a high temperature, a new, continuous cough or a loss or change to your sense of smell or taste)
- you've tested positive for COVID-19 – this means you have the virus
- someone you live with has symptoms or tested positive
- someone in your childcare or support bubble has symptoms and you’ve been in close contact with them since their symptoms started or during the 48 hours before they started
- someone in your childcare or support bubble tested positive and you’ve been in close contact with them since they had the test or in the 48 hours before their test
- you've been told you've been in 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
- you have arrived in England from abroad (not including Ireland, the Channel Islands, the Isle of Man or other parts of the UK) – see GOV.UK: how to quarantine when you arrive in England
What is a support bubble?
If you think you've been in contact with someone who has COVID-19, but you do not have symptoms and have not been told to self-isolate, continue to follow social distancing advice.
