Clouds remain over second attempt at contact tracing app
MAJOR questions about the effectiveness of the coronavirus contact tracing app have been left unanswered, experts have warned on the eve of its launch.
Failure to demonstrate how the technology has performed during testing on the Isle of Wight and in the London borough of Newham risks denting public confidence as its success depends on uptake, the Health Foundation said.
Prof Lilian Edwards, an expert on technology law at Newcastle University who advised on the UK’s first attempt at a contact tracing app, told The Daily Telegraph: “It is odd that after extensive trials, we still don’t know what the false positive and false negative rates are for being identified as a close contact.”
A Department of Health and Social Care spokesman said trials had shown the app was accurate, adding: “Ensuring a wide range of people download and use the app is essential.”
The new contact tracing app, NHS Covid-19, will be released in England and Wales tomorrow following months of delays, technical hitches and privacy issues.
Similar apps are already available in Scotland and Northern Ireland.
