The test and trace system which has launched in England is the key that will "unlock the prison" of lockdown, the prime minister has said.
If you suspect you have Coronavirus you can order a test by dialling 119 or visiting NHS.uk/coronavirus.
If your test comes back positive, you will be asked to give details of people you have been in "close contact" with. That is defined as people you have been within two metres of for more than 15 minutes without protective equipment.
Those people who have been in close contact with you will be contacted by NHS Test and Trace and told to isolate for 14 days, even if they are asymptomatic.
This scheme differs from the contact tracing app currently being tested on the Isle of Wight, which also identifies people unknown to someone who tests positive.
