It's the same for Norway. This website report 400 cases, 4 deaths and 22 recoveries. These are quite far off from the actual official numbers. The official numbers are released once per day at 18:00, by the Norwegian institute of Public Health [0], and VG (a newspaper) are keeping the numbers updated [1] with reports coming from municipalities and hospitals around the country [1]. The last official numbers (from yesterday) were 489 cases, 0 deaths, 1 recovery. The last numbers from VG are 642 cases, 0 deaths, 1 recovery.

One of the relevant data sources listed is "Mapping 2019-nCoV" https://systems.jhu.edu/research/public-health/ncov/ , and that shows Germany as having 3 deaths and 25 recovered cases. Perhaps these are getting falsely aggregated to give 28?

Ok, that makes this website completely worthless at the moment.

While the site and dataset is good, that particular link doesn't work well on mobile Android Chrome. This one works a treat https://gisanddata.maps.arcgis.com/apps/opsdashboard/index.h...

The data source for Wolfram is the John Hopkins University dataset. Here, there are listed 25 recovered cases for Germany. The erroneous number 28 might come from the calculation 25 + 3.

So the dataset is good, the calculation rubbish. Says a lot about the site. Why don't we just stick to the WHO, and the official last cal sources (CDC, Johns Hopkins, Robert Koch, whatever)?
