What role can technology play in helping to fight coronavirus? I’ve been keeping a close eye on the potential for smartphones to help contact tracing programmes become faster and more accurate.

While some national health authorities have raced to deploy contact tracing apps for their citizens’ smartphones, here in the UK it’s been a bumpy ride – as I wrote earlier in the summer.

Reporting for BBC Newsround, I gave an update on what happened to the NHS COVID-19 app in England, as well as how other home nations chose to move with their own apps.

Since this report, Apple and Google have pushed ahead with plans to integrate contact tracing right into their smartphones. Exposure Notifications Express means that a dedicated app may no longer be necessary to enable contact tracing.
