National surveillance of SARS-CoV-2 in wastewater

The virus SARS-CoV-2, which causes COVID-19, can be found in the feces of some infected individuals and consequently in wastewater. By examining wastewater for the presence of SARS-CoV-2, it is possible to understand the level of infection in the area from which the wastewater is collected.

National overvågning af SARS-CoV-2 i spildevandet (In danish)

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 2 the SARS-CoV-2 concentration in the wastewater, indicating the amount of SARS-CoV-2 circulating in the population, is lower than in the previous week and is now at a low level.

The national growth rate, showing the average weekly growth over the past three weeks, was not calculated this week due to too few data points as a result of fewer sampling days during Christmas and New Year.

The figure illustrates the concentration of SARS-CoV-2 in the wastewater along with the weekly number of hospitalized patients due to covid-19
