The figure below shows the concentration of SARS-CoV-2 in the wastewater based on measurements from all sampling sites. The level of concentration in the wastewater and this week's growth rate are also indicated in the figure.

In week 25, the concentration of SARS-CoV-2 is at a higher level than the previous week.

The national growth rate, showing the average weekly growth over the past three weeks, shows an increase in the SARS-CoV-2 concentration corresponding to the category "strong increase".
