The NHS Test and Trace app has been relaunched in England, with public trials starting on the Isle of Wight yesterday, the Government has announced.
The new app will also be rolled out to residents in the London borough of Newham, before being made available to the rest of the country, the Department of Health and Social Care (DHSC) said.
It comes as Northern Ireland has also launched its contact tracing app in recent weeks, using Apple and Google technology to anonymously alert users if they have been in close contact with someone who has tested positive for the virus.
England’s new app has been relaunched two months after the Government stopped using its previous in-house built app, due to ‘a number of technical challenges’ it said were irresolvable, including technical restrictions affecting its use with Apple phones.
It also adopts the Apple and Google system used in Northern Ireland and other countries to help ensure it is ‘safe, simple and secure’, the DHSC said.
It uses Bluetooth to keep an anonymous log on the time and distance a person has spent near any other person using the app, so it can alert them if that individual later tests positive for Covid-19 and direct them to getting their own test.
The new version will also send alerts informing users about the Covid-19 threat level in their area and will allow them to scan a QR code, alerting them if they have recently visited a venue where they may have come into contact with a Covid case.
The trial is this time being extended to Newham, in addition to the Isle of Wight, because it is an area with ‘a diverse population who might be more at risk to the virus’, DHSC said.
Dido Harding, executive chair of the NHS Test and Trace programme, said: ‘It’s really important that we make it as easy as possible for everyone to engage with NHS Test and Trace.
‘By launching an app that supports our integrated, localised approach to NHS Test and Trace, anyone with a smartphone will be able to find out if they are at risk of having caught the virus, quickly and easily order a test, and access the right guidance and advice.’
She added: ‘There is no silver bullet when it comes to tackling coronavirus. The app is a great step forward and will complement all of the work we are doing with local areas across the country to reach more people in their communities and work towards our vision of helping more people get back to the most normal life possible at the lowest risk.’
Earlier this week the Government announced an overhaul of the NHS Test and Trace programme in England to enable local authorities to take a greater role in contact tracing.
Under the new system, local councils will take over where the national team has failed to reach a resident within a certain time frame. In some pilot areas, this has involved local authority teams and voluntary partners visiting people at home.
