Spread of the virus

Virus particles in wastewater Gelderland-Midden

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 less testing is now being done (at the GGD and through self-testing), waste water research is important to monitor the virus and to recognize a possible revival of the virus.

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