You should not arrange to have a PCR test if you have previously received a positive PCR test result in the last 90 days, unless you develop any new symptoms of COVID-19, as it is possible for PCR tests to remain positive for some time after COVID-19 infection.
Even if you are vaccinated, you can still be infected with COVID-19 and pass it on to others. If you are identified as a contact of someone with COVID-19 but you are not required to self-isolate, you can help protect others by following the guidance on how to stay safe and help prevent the spread. As well as getting a PCR test, you may also consider:
limiting close contact with people outside your household, especially in enclosed spaces
wearing a face covering in enclosed spaces and where you are unable to maintain social distancing
limiting contact with anyone who has an underlying health condition that puts them at higher risk of severe illness if infected with COVID-19
taking part in twice weekly LFD testing
This advice applies until 10 full days after your most recent contact with the person who has tested positive for COVID-19.
If you are a health or social care worker who has been identified as a close contact and are exempt from self-isolation, there is additional guidance available that you should follow to reduce the risk of spread of COVID-19 in these settings.
Children and young people aged under 18 years 6 months who usually attend an education or childcare setting and who have been identified as a close contact should continue to attend the setting as normal. They do not need to wear a face covering within the setting, but it is expected and recommended that these are worn when travelling on public or dedicated transport.
If you develop symptoms at any time, even if these are mild, self-isolate immediately, arrange to have a COVID-19 PCR test and follow the guidance for people with COVID-19 symptoms.
I think I have had contact with someone who has tested positive for COVID-19, but I have not been notified and advised to self-isolate. What should I do?
Contacts who need to self-isolate will usually be notified and advised to do so by NHS Test and Trace, including by the NHS COVID-19 app. If you believe that you are a contact of someone with COVID-19 but have not yet been notified by NHS Test and Trace, you should carefully follow the guidance on how to stay safe and prevent the spread of COVID-19. In this circumstance you can arrange to take a PCR test, even if you do not have symptoms, because you may be at higher risk of being infected.
