NHS Covid-19 app upgrade increases 'accuracy' in identifying close contacts

THE NHS Covid-19 app has been upgraded to detect close contacts more accurately and users can now expect more high-risk notifications to be issued.

Due to the app's improved accuracy, users who are notified to self-isolate should take warnings even more seriously, said a statement from the department of health and social care (DHSC).


The NHS Covid-19 app, which was built to anonymously track and warn people who are at risk of having been infected by the disease in England and Wales, relies on a Bluetooth-enabled API developed by Apple and Google for health services to develop decentralised, privacy-preserving contact-tracing tools.

Phones that are fitted with the app regularly generate random, anonymous IDs that are exchanged via Bluetooth whenever two devices that have downloaded the app come into prolonged contact.

If someone later tests positive for Covid-19, they have the option to submit their results to the app, which in turn triggers alerts to contacts deemed to be at risk of infection by the algorithm.

Gaby Appleton, NHS director of product for Test and Trace, has said that NHS Covid-19 app is the first in the world to integrate the latest upgrade in API by Google and Apple.

“The team behind the app are continually working to improve its accuracy and user experience, to make it as simple as possible to keep users and their loved ones safe. We are thrilled that over 19 million people have chosen to download the app to help protect their loved ones while preserving their privacy, and that over 680,000 QR codes have been created by businesses to support digital contact tracing," said Appleton.

“This update builds on that success by increasing accuracy, and also removing ‘ghost’ exposure notifications, meaning users will only be notified if they need to self-isolate. The more people who use the app, the better it works, so I encourage all those who have not yet downloaded the app to do so.”

The app uses a combination of distance, proximity and infectiousness of a contact to calculate the risk threshold at which someone is notified to self-isolate.

The app will be updated to better estimate distance between users to increase the accuracy of close contact notifications sent out by the app.

The improved algorithm was developed in collaboration with scientists from the Alan Turing Institute, and health services are now confident that the technology is highly accurate. The DHSC is, therefore, prepared to let the app issue more alerts to users than before, advising those who are at high risk of infection to self-isolate.

Mark Briers of The Alan Turing Institute said: “It is thanks to the hard work of the NHS Covid-19 app development team and colleagues at the Turing Institute that we have been able to exploit the updated API technology in this way.

“This update increases the accuracy, meaning those most at risk will be notified to self-isolate.”

The app is also set to become interoperable with contact tracing apps in Scotland, Northern Ireland, Jersey and Gibraltar.

"We are currently consulting with the National Cyber Security Centre to ensure this process is secure and reliable, functioning effectively to benefit everyone using contact tracing apps across the UK. We expect this update to be released in early November," the statement further said.

British Steel to shut blast furnaces, up to 2,700 jobs at risk

BRITISH STEEL, owned by Chinese group Jingye, confirmed on Thursday that it will shut down its blast furnaces and steelmaking operations in England, attributing the decision to market challenges, tariffs, and rising environmental costs.

The closures, first proposed in late 2023, could lead to the loss of up to 2,700 jobs at the company’s main UK site in Scunthorpe, northern England, according to sources familiar with the matter.

Just Stop Oil ends direct action campaign after major policy success

The environmental activist group Just Stop Oil has announced an end to its disruptive direct action protests, declaring a significant victory in its campaign to halt new oil and gas developments. In a statement released by the organisation, the group confirmed it had successfully influenced government policy to abandon new fossil fuel exploration, marking a major turning point in the movement’s goals.

“Just Stop Oil's initial demand to end new oil and gas is now government policy, making us one of the most successful civil resistance campaigns in recent history,” the group’s statement read. It went on to claim responsibility for having kept over 4.4 billion barrels of oil in the ground, while legal victories in the courts have ruled new oil and gas licences unlawful.

European Union urges citizens to stockpile food and supplies amid risk of war

The European Union (EU) has advised its 450 million citizens to stockpile essential items, including food and water, to prepare for potential emergencies. This call to action is part of a broader strategy to improve disaster preparedness across the 27-nation bloc, as it faces increasing risks from war, cyberattacks, climate change, and public health crises.

The EU’s recommendation comes in light of recent global developments that have raised concerns about security and stability. Citizens are encouraged to have enough food, water, medicine, and other essential supplies to last at least 72 hours during a crisis.
