You must self-isolate for 10 days if you live with (or are in a support bubble with) someone who:

• has symptoms of coronavirus and tested positive, had an unclear result, or did not have a test
• tested positive but has not had symptoms

This is because it can take 10 days for symptoms to appear.

The 10 days start from:

• when the first person in your home or support bubble started having symptoms
• the day they were tested if they have not had symptoms – but if they get symptoms after they were tested, self-isolate for a further 10 days from when their symptoms start
