COVID-19: NHS Test and Trace app has prevented 600,000 cases, study suggests

As many as 600,000 coronavirus cases have been prevented as a result of the NHS COVID-19 app, new research suggests. Scientists at The Alan Turing Institute and Oxford University found that for every 1% increase in app users, the number of infections falls by up to 2.3%. The analysis, which is yet to be peer-reviewed, is based on data gathered in between the app launching in September and the end of last year. 'The impact of the app could be increased by more people using it,' said Professor Christophe Fraser at the University of Oxford.
