The new NHS Test and Trace service launched on Thursday 28 May across England.
The service will help identify, contain and control Coronavirus, reduce the spread of the virus and save lives.
Now anyone who tests positive for coronavirus will be contacted by NHS Test and Trace and will need to share information about their recent interactions. This could include household members, people with whom they have been in direct contact, or within 2 metres for more than 15 minutes. People identified as having been in close contact with someone who has a positive test must stay at home for 14 days, even if they do not have symptoms, to stop unknowingly spreading the virus. If those in isolation develop symptoms, they can book a test at nhs.uk/coronavirus or by calling 119.
If they test positive, they must continue to stay at home for 7 days or until their symptoms have passed. If they test negative, they must complete the 14-day isolation period. Members of their household will not have to stay at home unless the person identified becomes symptomatic, at which point they must also self-isolate for 14 days to avoid unknowingly spreading the virus.
