If you get symptoms of coronavirus (COVID-19) again, you must self-isolate immediately and ask for a test.
The symptoms are a high temperature, a new, continuous cough or a loss or change to your sense of smell or taste.
If someone you live with (or someone in your support bubble) gets symptoms again, you must also self-isolate immediately.
What is a support bubble?
A support bubble is where someone who lives alone (or just with their children) can meet people from 1 other household.

You must self-isolate again even if you've had a positive test result for coronavirus before. You probably have some immunity to coronavirus but it's not clear how long it will last.
You must not leave your home if you're self-isolating.
