Background

Since February 25, 2020 Switzerland has been affected by COVID-19. Modelling predictions show that this pandemic will not stop on its own and that stringent migitation strategies are needed. Switzerland has implemented a series of measures both at cantonal and federal level. On March 16, 2020 the Federal Council of Switzerland declared “extraordinary situation” and introduced a series of stringent measures. This includes the closure of schools, restaurants, bars, businesses with close contact (e.g. hair dressers), entertainment or leisure facilities. Incoming cross-border mobility from specific countries is also restricted to Swiss citizens, residency holders or work commuters. As of March 20, 2020 mass gatherings of more than five people are also banned. Already in early March various cantons had started to ban events of various sizes and have restricted or banned access to short- and long-term care facilites and day care centers.

The aim of this project is to collect and categorize these control measures implemented and provide a continously updated data set, which can be used for modelling or visualization purposes. This is a collaborative project initiated by Fabienne Krauer and Simone Baffelli. The following persons have contributed substantially to the data collection: Johannes Bracher, Maria Bekker-Nielsen Dunbar, Muriel Buri, Nicolo Lardelli, and Jonas Oesch. These data can be used for research. Please cite this dataset using the DOI 10.5281/zenodo.3749747.

Data collection

We collect the date/duration and level of the most important measures taken in response to COVID-19 from official cantonal and federal press releases. We consider the following measures:

measure levels comment
carefacilities 0=no restriction
1=restricted access
2=access prohibited
includes hospitals, nursing and disabled homes
casemanagement 0=none
1=in place
includes testing, isolation, quarantine and triage
daycare 0=no restriction
1=restricted access or closed
includes Krippe and Hort
events 0=no restriction
1=events > 1000 persons banned
2=events > 500 persons banned
3=events > 100 persons banned
4=events > 50 persons banned
5=events > 10 persons banned
6=events > 5 persons banned
includes events and mass gatherings of any kind
stayathome 0=no
1=yes
Switzerland does not have an official “lockdown” policy in the sense of a shelter-in-place order. This category means a “strong recommendation to stay at home”.
mobilityint 0=no restriction
1=restriction of cross-border mobility
2=closing of borders
publicoffices 0=no restriction
1=closed

Results

The following figures are based on the data until April 6, 2020. The “extraordinary situtation” will be in place until April 26, 2020.

The graph below shows the time series of incident confirmed cases (grey) and the incident deaths (black) as well as the development of some control measures by Canton. The red line marks the federal ordinance of March 16, 2020 (“extraordinary situation”). The pink shades indicate the ban of events or mass gatherings that were implemented by the Cantons.

For Zürich we can add time-resolved mobility data available from Iphone users (provided by Apple). The data represent relative changes from the baseline prior to COVID-19 (right axis of the plot below):
