NHS Covid-19 app to issue more self-isolate alerts

An update to the Covid-19 contact-tracing app operated by NHS England and Wales is set to issue more self-isolation alerts. This follows modifications to the app’s algorithm, making contact matches more reliable. The app required a high risk score before activating a self-isolate alert, but the technology has advanced to give more accurate readings of distancing measures. In time, this should lead to more alerts, but the app cannot be used to enforce fines for non-compliance with self-isolation advice.
