The NHS says if you get symptoms of coronavirus again you should “self-isolate immediately and get a PCR test”, even if the symptoms are mild.
The health body notes that you can temporarily leave self-isolation for a number of reasons, for example to get urgent health services, or to avoid harm, for example if you are at risk of domestic abuse.
The UK Health Security Agency (UKHSA) has confirmed that from 11 January, people without COVID-19 symptoms will no longer need to confirm a positive lateral flow test with a PCR.
The health body notes: “Self-isolate 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.”
