Thanks to the awesome work of Daniel Probst, collecting per canton data and publishing it on https://github.com/daenuprobst/covid19-cases-switzerland, I was able to pull this quick heatmap together, showing latest (ie daily) confirmed cases of COVID-19 in Switzerland, updated constantly (whenever source data changes).
note: unreported cantonal data is backfilled from the previous day
(previous post on this topic: https://www.musings.ch/2020/03/13/covid-19-heatmap-schweiz/)
And since heatmaps over broad areas are not necessarily useful, here’s a map of cantons affected.
