Coronavirus variants

When a virus multiplies it can keep changing slightly. Sometimes a change makes a virus behave differently. This change creates a variant of the virus. Some variants can be more infectious or make people more sick. Vaccines may also be less effective against a variant. It is therefore important to know what variants occur in the Netherlands.

Coronavirus variants

This table shows what percentage of infections can be attributed to the different coronavirus variants detected in the Netherlands. The first column shows the name of the variant and the country in which the variant was first detected. The second column shows the percentages of each variant. The table also shows whether the percentage of a variant has increased, decreased or remained the same in relation to the previous measurement.

The information in the table is for the period from 25 April to 1 May. The data below is based on pathogen surveillance, which is the actual measured data that is used to estimate future trends. The table is updated weekly. Read more about the numbers shown here in the Explanation of the data presented.

Coronavirus variants over time

This graph shows how frequently a variant has been detected in the Netherlands. We only show variants designated as variants of concern by the European Centre for Disease Prevention and Control (ECDC) and the World Health Organization (WHO) because of the potential risk that they pose. The samples of positive tests collected in the most recent week are still being analysed, so the figures for this week are still incomplete.
