CORONASTEP Report 26 SARS-CoV-2 Sewage Surveillance in Luxembourg

Vers le niveau supérieur

This report 26 presents the results of SARS-CoV-2 contamination of wastewater at the inlet of all wastewater treatment plants (WWTPs) for week 47. Two separate sampling days, Tuesday and Thursday, were analysed during this week, with eleven and thirteen wastewater samples respectively. Most of the WWTPs were therefore analysed twice, with the exception of Hespérange and Boevange-sur-Attert.
During week 47, the SARS-CoV-2 RNA flows in the treatment plants were very comparable to those observed during from weeks 44 to 46. The level of contamination remains in the thirteen treatment plants analysed at high values of SARS-CoV-2 fluxes, indicating a still very high prevalence of the virus in wastewater (Figures 1a and 1b). For the second time, the data collected this week seem to indicate a slight downward trend, although it remains very low. This trend will have to be confirmed in the coming days or weeks.
At the scale of WWTPs, the SARS-CoV-2 RNA fluxes show sawtooth variations at high levels, giving no clear signs of decrease or increase.
