NHS launches COVID-19 track and trace app

The app launches today, and after positive trials and rigorous testing is an important new tool to work alongside traditional contact tracing to help reduce the spread of the virus.

It will be available to those aged 16 and over in multiple languages. It forms a central part of the NHS Test and Trace service in England and the NHS Wales Test, Trace, Protect programme – identifying contacts of those who have tested positive for coronavirus.

The contact tracing element of the app works by using low-energy Bluetooth to log 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 free test if needed and get your test results.

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 (not GPS). 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. No personal data is shared with the government or the NHS.

UK government Health and Social Care Secretary Matt Hancock said, “We are at a tipping point in our efforts to control the spread of this virus. With infection rates rising we must use every tool at our disposal to prevent transmission, including the latest technology.

“We have worked extensively with tech companies, international partners, and privacy and medical experts – and learned from the trials – to develop an app that is secure, simple to use and will help keep our country safe.

“Today’s launch marks an important step forward in our fight against this invisible killer and I urge everyone who can to download and use the app to protect themselves and their loved ones.”

From today certain businesses in England are required by law to display NHS Test and Trace QR codes so customers with the NHS COVID-19 app can use them to check-in. QR codes will help businesses meet their legal requirement to log contact details and allow public health leads to send alerts based on whether people have checked in at venues. So far, more than 160,000 businesses have already downloaded QR codes. Venues in Wales that are legally required to collect and keep a record of visitors will still need to do so.
