The app launches today [Thursday 24] after positive trials and will be a useful tool when used alongside Wales’ successful manual contact tracing system.
It will be available to those aged 16 and over, and forms a central part of the NHS Wales Test, Trace, Protect programme identifying contacts of those who have tested positive for coronavirus.
The roll-out of the app in Wales coincides with a national campaign around how people in Wales can best support the NHS Wales Test, Trace, Protect programme, including only getting a test if they are showing symptoms; self-isolating when required; and working with local contact tracers if they are contacted.
Wales’ contact tracing system – which is a publicly-run service and locally delivered – is working well and has seen a very high contact and trace rate. Latest stats show 94% of cases are being successfully contacted.
The app works by logging the amount of time you spend near other app users, and the distance between you, so it can alert you if someone you have been close to later tests positive for COVID-19, even if you don’t know each other.
The app will advise you to self-isolate if you have been in close contact with a confirmed case. It will also enable you to check symptoms, book a test if needed and get your test results.
Wales’ Health Minister Vaughan Gething said: “The launch of the NHS COVID-19 app is an important part of Wales’ coronavirus response, supporting the NHS Wales Test, Trace, Protect programme. The more people who download and use this app, the more it will help us to prevent the spread of COVID-19.
“We have worked closely with the app development team to ensure it works seamlessly across Wales and England, providing people with the right advice based on where they live. In Wales, the app will complement our existing contact tracing and testing services and will further support our coordinated response to COVID-19 at both a local and national level.
“I strongly encourage everyone in Wales to download and use the app to keep Wales safe.”
The app has been designed with user privacy in mind, so it tracks the virus, not people and uses the latest in data security technology to protect privacy. The system generates a random ID for an individual’s device, which can be exchanged between devices via Bluetooth. These unique random IDs regenerate frequently to add an extra layer of security and preserve anonymity.
The app does not hold personal information such as your name, address or date of birth, and only requires the first half of your postcode to ensure local outbreaks can be managed.
Today the UK’s major mobile network operators, including Vodafone, Three, EE and O2, Sky and Virgin, have confirmed that all in-app activity will not come out of customers’ data allowance.
In a joint statement Apple and Google said:
“We built the exposure notifications system to enable public health authorities in their efforts to develop apps to help reduce the spread of the virus while ensuring people can trust in the privacy-preserving design. We are committed to supporting the Government’s effort to launch an app based on this technology.”
Whilst the app will be a major support for the contact tracing system, Welsh residents are being reminded to continue to keep Wales safe and prevent the spread of COVID-19 by:
- Always keeping a distance
- Washing hands regularly
- Working from home wherever possible
- Following local restrictions
- Following the rules about meeting people
- Staying at home if you or anyone in your extended household has symptoms.
