The Corona-Warn-App (CWA) is one of the measures that has been put in place to contain the pandemic over the last year. How effective is the app as a digital tool and what are its benefits? Over the next few weeks, we will be using this blog to publish answers to these questions as well as results from the research undertaken by the Robert Koch Institute.
Corona-Warn-App: Event-related survey (1/2)
An English version of this science blog article will follow in due course. Please take a look at the German version until the English version is available.
About the Effectiveness and Benefits of the Corona-Warn-App
On 16 June 2020, the CWA was made available for download in the Apple App Store and the Google Play Store. By 31 May 2021, it had been downloaded 28.1 million times. The CWA, which provides digital contact tracing for people with SARS-CoV-2, is published by the Robert Koch Institute on behalf of the German government.
Some of the most important aspects of the app that have been discussed since its introduction are its effectiveness and benefits in terms of contact tracing for people with SARS-CoV-2. Very few empirical data are currently available to analyse these issues. Therefore, it is crucial that the data needed to do so are collected and analysed, and this has been planned since the app was developed.
