CORONASTEP Report 71 (Week 18) SARS-CoV-2 Sewage Surveillance in Luxembourg

This report 71 presents the results of SARS-CoV-2 contamination of wastewater at the entrance of the 13 wastewater treatment plants analysed during the week 18 of 2021.

The SARS-CoV-2 RNA flux measured in wastewater treatment plants during week 18 shows a moderate national prevalence of the virus, with daily fluctuations during the week. However, the dynamics of SARS-CoV-2 contamination appear to show a steady downward trend over the past several weeks.

The same trend (constant or decrease patterns) is observed at the level of each wastewater treatment plant

individually.
