What to do if you get coronavirus (COVID-19) symptoms again

If you get symptoms of coronavirus (COVID-19) again, you must self-isolate immediately and get a PCR test (test that is sent to a lab).

The symptoms are:

  • a high temperature
  • a new, continuous cough
  • a loss or change to your sense of smell or taste

You should also self-isolate again if:

  • someone you live with gets symptoms
  • someone in your childcare or support bubble gets symptoms and you were in close contact with them since their symptoms started or during the 48 hours before they started

The person with symptoms should get a test.

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.

Find out more about making a support bubble with another household on GOV.UK.

You must self-isolate again even if you've had a positive test result for COVID-19 before. You probably have some immunity to the virus but it's not clear how long it lasts.
