New research article accepted for publication in Scientific Reports

(04.05.2021) Our new journal article “How detection ranges and usage stops impact digital contact tracing effectiveness for COVID-19“ by Konstantin Pandl, Scott Thiebes, Manuel Schmidt-Kraepelin, and Ali Sunyaev has been accepted for publication in the journal Scientific Reports.

To combat the COVID-19 pandemic, many countries around the globe have adopted digital contact tracing apps. Various technologies exist to trace contacts that are potentially prone to different types of tracing errors. Here, we study the impact of different proximity detection ranges on the effectiveness and efficiency of digital contact tracing apps. Furthermore, we study a usage stop effect induced by a false positive quarantine. Our results reveal that policy makers should adjust digital contact tracing apps to the behavioral characteristics of a society. Based on this, the proximity detection range should at least cover the range of a disease spread, and be much wider in certain cases. The widely used Bluetooth Low Energy protocol may not necessarily be the most effective technology for contact tracing.
