The government has announced it is to trial a new contact-tracing app on the Isle of Wight as part of the fight against coronavirus.
The new app – which will ask for the first part of a user’s postcode – will allow people to alert the NHS if they have symptoms and book a Covid-19 test.
It will then alert others who may have come into contact with the user to tell them to isolate for 14 days. If the first person’s test comes back negative, the app tells both them and their contacts to come out of isolation and carry on as normal.
But if their test is positive, everyone carries on isolating – with the contacts told to book their own Covid-19 test if they themselves develop symptoms.
