General
Coronadashboard data explained contains all open data in which the safety regions were reported. Each reference per subject, with a reference to the correct sources at RIVM and Statistics Netherlands (CBS) is listed below.

Since 20 April 2023, the data on the dashboard is no longer shown per security region.
Fewer updates and information needed for monitoring the coronavirus
Less data is collected, which means that some graphs and pages on the dashboard can no longer be updated, such as graphs about the number of positive tests. The number of updates per week has also been reduced.
The resistance to corona in the Netherlands is now high. Few people become seriously ill from the current virus variant. The virus has gone from a pandemic to an endemic. As a result, the GGD test streets are closed and the latest corona advices have been lifted.
The virus will continue to be monitored. In the event of an revival of the virus, the Corona dashboard can be supplemented with data again and the update frequency can be increased.
Value of
On the dashboard we use 'Value of' to indicate which date (period) the figures refer to.
Obtained on
We use 'Obtained on' to indicate the date when we received the data from our sources.
This way we make it clear how up-to-date the data is and when we received it, especially for indicators that look back in time.
For example:
'Value of Thursday 13 April 2023 obtained on Friday 28 April 2023'.
To be able to compare municipalities with each other, we convert some figures into figures per 100,000 inhabitants. This way we can compare larger municipalities and smaller municipalities.
Otherwise, municipalities such as Amsterdam and Rotterdam, for example, would always have high figures, because many more people live there than in smaller municipalities.
Calculation example
In Katwijk, 47 residents have had a positive test result out of 65,995 residents. The calculation is 47 / 65,995 x 100,000 ≈ 71.2.
Per 100,000 inhabitants, 71.2 inhabitants in Katwijk had a positive test result.
In Amsterdam, 455 residents have had a positive test result out of 873,338 residents. The calculation is 455 / 873,338 x 100,000 ≈ 52.1.
Per 100,000 inhabitants, 52.1 inhabitants in Amsterdam had a positive test result.
Variant under monitoring (VUM)
The term "variant under monitoring" (VUM) is used to indicate a specific variant of a virus that is closely monitored by health authorities and experts. These variants are under scrutiny for certain properties that may be of interest or of potential concern, such as changes in genetic material, transmission patterns, or possible effects on public health.
When a variant is classified as "variant under monitoring", this means that there are indications that changes have occurred in the virus, but that there is not yet enough information available to determine whether these changes have a significant impact on, for example, the spread, the severity of illness, or the effectiveness of vaccines and treatments.
Also, as more data is collected and analyzed, a variant can be upgraded to a "variant of interest" (VOI) or even a "variant of concern" (VOC), depending on potential risks to public health.
Variant of interest (VOI)
The term "variant of interest" (VOI) is used to denote a specific variant of a virus that is receiving additional attention because of certain properties that could potentially be relevant to public health. When a variant is labeled as a "variant of interest," it means there is evidence that the variant has certain changes in its genetic material that may be of interest or concern, but more research is needed to fully understand the implications.
Variants of interest are closely monitored by health authorities and experts to determine whether they may be associated with particular traits, such as increased transmission, decreased susceptibility to antibodies (for example, from vaccination), or other potential public health consequences. It is an intermediate step between a "variant under monitoring" (VUM) and a "variant of concern" (VOC).
If more evidence and data become available and there are indications that the variant actually has an impact on public health, it may be upgraded to a "variant of concern".
Variant of concern (VOC)
The term "variant of concern" (VOC) is used to refer to a specific variant of a virus that is considered to be of concern. For example, because of evidence or strong indications that this variant can have important consequences for public health. When a variant is classified as a "variant of concern", it means that there are reasons to believe that the variant has certain properties that could lead to increased transmission, more severe disease, reduced effectiveness of vaccines or treatments, or other relevant risks.
The classification as a "variant of concern" implies that sufficient scientific information and data has been collected to suggest that the variant may actually have a negative impact on public health. This can lead to increased monitoring, research and possibly measures to control the spread and consequences of the variant.
Health authorities and researchers remain constantly on the lookout for variants of concern in order to understand the evolution of the virus and implement effective responses to minimize its spread and impact.
