Virus particles in wastewater

If you are infected with the corona virus, there are often virus particles in your stool. Wastewater is collected at treatment plants and tested for virus particles at RIVM.

Because the GGD is no longer testing and people less self-test, it is important to examine waste water to monitor the virus and to recognize a possible revival of the virus on time.

Measurement of the average number of virus particles

To measure the average number of virus particles per 100,000 inhabitants, we use the last measurement of each waterwaste treatment plant.

If the last measurement is older than nine days, for example due to maintenance on the installation, it does not count in the average.

All waterwaste treatment plants collect samples on average three times a week, which are measured by RIVM.
