English webpage for the national wastewater surveillance of SARS-CoV-2 

For more than two years, weekly results from the national surveillance of SARS-CoV-2 in the wastewater have been published at Statens Serum Institut’s Danish webpage. The virus SARS-CoV-2, which causes COVID-19, can be found in the feces of some infected individuals and consequently in wastewater. Hence, by surveilling the SARS-CoV-2 concentrations, we can monitor changes in the level of infection in the population, both nationally and regionally.

Currently, 29 wastewater samples are taken twice a week from treatment plants across Denmark. The number of RNA-copies in each sample are quantified in SSI laboratories using RT-qPCR, and subsequently, the results are validated and processed.

National and regional results, as well as results from individual sites, are made available to download on the webpage.
