LONDON: A contact tracing app designed to let people know if they have been in close contact with someone who tested positive for Covid-19 could be rolled out widely in Britain in two to three weeks, a senior official said on April 28.

Matthew Gould, chief executive of the National Health Service's technology group NHSX, told a parliamentary committee that the app, which will notify contacts if a person tests positive for Covid-19, would first be tested locally.

The app, and wider testing and tracking programme, is seen as key to help easing social distancing restrictions in Britain, which have all but shut the economy and stopped people going about their daily lives.

"We hope in the next couple of weeks we'll be in a position to roll it out in a small area," Gould said.

Asked when it could be deployed more widely, he said it would depend on the overall programme to ease the lockdown but that "subject to it performing in the trials, and the smaller area in the way we expect, I would expect it technically to be ready for a wider deployment in two to three weeks".
