CORONASTEP Report 100 (Week 41) SARS-CoV-2 Sewage Surveillance in Luxembourg

This report 100 presents the results of SARS-CoV-2 contamination of wastewater at the entrance of the 13 wastewater treatment plants (WWTPs) analysed during the week 41 of 2021. The WWTPs of Hespérange and Boevange were analysed only once this week.

The SARS-CoV-2 RNA flux measured in WWTPs this week show again a high national prevalence of the virus, with a SARS-CoV-2 flux between 5 and 6 x 1011 RNA copies per day per 100,000 equivalent-inhabitants. The virus RNA level was closely to that observed during the previous week, with a slightly increasing trend.

An overall constant trend is observed for most of the wastewater treatment plants analysed, excepted for the WWTP of Wiltz where an increase was detected again noticeable this week.
