SARS-CoV-2 Cases communicated by Swiss Cantons and Principality of Liechtenstein (FL)
Since 8 June 2020 most cantons are not communicating cantonal case numbers more often than once or twice per week, and neither over weekends. The data in our repository is kept up-to-date with the latest communicated data by Swiss cantons and FL.
The Federal Office of Public Health FOPH is issueing daily case number updates (incl. on weekends) on its website: "Confirmed coronavirus infections, deaths, epidemiological situation"
Due to different sources, definitions and methodologies the values communicated by cantons may differ from those communicated by the FOPH.
We are providing a common official OGD dataset of SARS-CoV-2 case numbers, which are communicated by official Swiss canton's (26 cantons, abbreviations see below) and Principality of Liechtenstein's (abbreviation: FL) sources.
The infection rates refer to the infection with SARS-CoV-2, whereas the disease caused by the virus is called Covid-19.
We are providing SARS-CoV-2 case numbers in machine-readable form (CSV) as OGD resources (Open Government Data), that have been published by official sources (Cantons and FL) online. Sources are specified with the respective URL(s).
Case numbers include persons tested and treated in the respective Canton resp. Principality of Liechtenstein. Important: Since 09.03.2020, only persons who meet certain test criteria are tested (see e.g. with the Canton of Zurich "Testkriterien" at www.gd.zh.ch/coronavirus).
The data is updated regularly - if available daily. Times of collection and update of the data may vary. We are specifying the date of the last reporting, and - if available - a time-stamp, too.
The data is both automatically and manually updated, and regularly checked. We are performing a complete manual update and verification once a day; this "roundtrip" starts at 6pm CET. It is usually completed within 120 minutes.
There is a merged file of all Cantons and FL that is automatically updated for use in data analysis.
You can get started exploring the data with visualise.ipynb (run it in your browser).
We are available to advise and support interested authorities, how to easily complete both historized data, and missing columns. You can reach us:

Data structure
Data on Cantonal Case Numbers
Single Cantonal Files
https://github.com/openZH/covid_19/tree/master/fallzahlen_kanton_total_csv_v2
Merged File for all Cantons
https://github.com/openZH/covid_19/blob/master/COVID19_Fallzahlen_CH_total_v2.csv
The dataset containing the cantonal case numbers is structured as follows:
| Field Name | Description | Format | Note |
|---|---|---|---|
| date | Date of notification | YYYY-MM-DD | |
| time | Time of notification | HH:MM | |
| abbreviation_canton_and_fl | Abbreviation of the reporting canton | Text | |
| ncumul_tested | Reported number of tests performed as of date | Number | Irrespective of canton of residence |
| ncumul_conf | Reported number of confirmed cases as of date | Number | Only cases that reside in the current canton |
| new_hosp | new hospitalisations since last date | Number | Irrespective of canton of residence |
| current_hosp | Reported number of hospitalised patients on date | Number | Irrespective of canton of residence |
| current_icu | Reported number of hospitalised patients in ICUs on date | Number | Irrespective of canton of residence |
| current_vent | Reported number of patients requiring invasive ventilation on date | Number | Irrespective of canton of residence |
| ncumul_released | Reported number of patients released from hospitals or reported recovered as of date | Number | Irrespective of canton of residence |
| ncumul_deceased | Reported number of deceased as of date | Number | Only cases that reside in the current canton |
| source | Source of the information | href | |
| current_isolated | Reported number of isolated persons on date | Number | Infected persons, who are not hospitalised |
| current_quarantined | Reported number of quarantined persons on date | Number | Persons, who were in 'close contact' with an infected person, while that person was infectious, and are not hospitalised themselves |
Note that only numbers communicated by the cantons are published in the files, i.e. it's possible that there are gaps, when a canton did not provide a certain number on a date. It's on purpose that the cumulative numbers are not carried forward if no new number is communicated.
Note about empty values vs. 0:
| Value | Meaning |
|---|---|
| 0 | canton communicated 0 for this variable on that date |
| empty | canton communicated nothing/did not provide a value for this variable on that date |
Confirmed Cases and Fatalities by Age, Gender and Pre-existing Conditions
Selected Cantons publish more detailed datasets, which are available in this directory: https://github.com/openZH/covid_19/tree/master/fallzahlen_kanton_alter_geschlecht_csv
| Field Name | Description | Format | Reporting Cantons |
|---|---|---|---|
| Date | ZH = Date of test result (NewConfCases) / Date of death (NewDeaths) BL = Date of death BS = Date of notification |
YYYY-MM-DD | |
| Area | Abbreviation of the reporting canton | ||
| AgeYear | Number | ZH,BS,BL | |
| Gender | Text | ZH,BS,BL | |
| NewConfCases | Number of Confirmed Cases | Number | ZH |
| NewDeaths | Number of Deceased | Number | ZH,BS,BL |
| PreExistingCond | Pre-Existing Conditions | Text | BL,BS |
Comparable data for the Canton Thurgau in a slightly different format is available on opendata.swiss.
