Swiss Cantons and Principality of Liechtenstein: Unified dataset

General description
This data is generated and validated daily using manual and automated procedures. Note that we only publish data that are reported by the Swiss Cantons and the Principality of Liechtenstein. Thus, gaps result if Swiss Cantons or the Principality of Liechtenstein do not report data for the specific date.

Canton Zurich: Variants of Concern

Note: ZH data is deprecated (2021-02-12) - this resource will not be updated further from 2021-02-12 as the week of 2021-02-15 will be used to analyse the completeness of the collection of available data and adjust the approach to which VOCs are tested.
Since 2021-02-19 FOPH publishes data for all Cantons ("virusVariants", https://www.covid19.admin.ch/api/data/context).
Variants of concern ('VOC') can not be detected by 'rapid' tests, but can be detected by PCR tests. Virus mutations are classified as being of concern because, among other things, they are more infectious than the wild type of the virus.
