Diagnosis key analysis (dka)

Deutsche Fassung

Statistical analysis of the daily diagnosis keys of the official German COVID-19 tracing app (Corona-Warn-App). The daily diagnosis key packages, which are distributed by the CWA server, are being analyzed with the diagnosis-keys toolset by mh-. These data can only be estimated, due to the decentralized architecture of the tracing app. Hence, all information are without any guarantee. All diagrams in this repository are licensed under CC BY-NC-SA. See coronawarn.app for more information about the COVID-19 tracing app for Germany.

Note: Since February 2021, exact statistical data are being published within the CWA, which are used by this page and make the estimation of data redundant.
