Spotlight on the dark figure: Exhibiting dynamics in the case detection ratio of COVID-19 infections in Germany

Abstract: The case detection ratio of COVID-19 infections varies over time due to changing testing capacities, modified testing strategies and also, apparently, due to the dynamics in the number of infected itself. In this paper we investigate these dynamics by jointly looking at the reported number of detected COVID-19 infections with non-fatal and fatal outcomes in different age groups in Germany. We propose a statistical approach that allows us to spotlight the case detection ratio and quantify its changes over time.… Show more

“…A result of this choice is that in ( 12)-( 15), asymptomatic individuals are no longer specifically accounted for; all infected persons are considered equally. For the specific case of COVID-19, this may be a more reasonable assumption at this point in time, as testing protocols have improved and larger portions of asympomatic patients are now detected [18,24].…”

“…Das Modell haben wir im Rahmen der COVID-19-Pandemie entwickelt und erprobt, allerdings ist seine Anwendbarkeit nicht auf diese beschränkt. Das Modell macht starken Gebrauch von nach Altersgruppen aufgelösten Daten, anders als andere mathematische Modelle zur direkten Schätzung der tatsächlichen Infektionszahlen [12,13]…”
