Contact-tracing apps prove that they save lives
A study published today in Nature shows that the NHS COVID-19 app for digital contact tracing, based on the DP3T protocol, averted between 300,000 and 600,000 COVID-19 cases in England and Wales. The researchers used data from the NHS to show and quantify the epidemiological impact of such privacy-preserving apps, which are now available around the globe to help control the pandemic.
