Coronadashboard data explained

This dashboard presents a lot of data on the developing coronavirus situation in the Netherlands. In this section we offer information on data sources and calculation methods as well as links to data files.

Keeping track of the virus

We keep track of the virus by following trends in various sources. Daily figures can fluctuate strongly. RIVM monitors current events and passes this on. We update the dashboard on Tuesday, Wednesday and Friday depending on what figures are available at that time. The frequency can be found at the top of the various pages. If the situation calls for it, we can adjust the update frequency of the figures again.
