If you live with someone who has symptoms, you'll need to self-isolate for 14 days from the day their symptoms started. This is because it can take 14 days for symptoms to appear. If more than 1 person at home has symptoms, self-isolate for 14 days from the day the first person started having symptoms. If you get symptoms, self-isolate for 7 days from when your symptoms start, even if it means you're self-isolating for longer than 14 days. If you do not get symptoms, you can stop self-isolating after 14 days.
