CORONASTEP Report 84 (Week 27-1) SARS-CoV-2 Sewage Surveillance in Luxembourg

This report 84 presents the results of SARS-CoV-2 contamination of wastewater at the entrance of the 8 wastewater treatment plants (WWTP) analysed at the beginning of the week 26 of 2021. The WWTPs of Hespérange, Boevange, Echternach, Grevenmacher and Ueberysren were not analysed here, but will be on the second day of analysis this week.

The SARS-CoV-2 RNA flux measured in wastewater treatment plants shows a high national prevalence of the virus, with a SARS-CoV-2 flux between 3 and 4 x 1011 RNA copies per day per 100,000 equivalent-inhabitants. The overall contamination level is therefore very similar to that observed at the end of the previous week.

Comparable trends are observed at the level of the individual treatment plants. The analyses of the day of sampling should confirm this result.
