CORONASTEP Report 18 SARS-CoV-2 Sewage Surveillance in Luxembourg

Vers le niveau supérieur

The present report 18 incorporates the results about the contamination of wastewater at the inlet of the wastewater treatment plants (WWTP) during week 44. During this week, the major WWTPs have been sampled twice in order to a finer picture of the virus dynamics in the wastewater.
Over the week, the total SARS-CoV-2 RNA flux of at the inlet of the WWTP showed variations between 2 to 4 × 1012 SARS-CoV-2 RNA copies per day and per 100,000 inhabitants (Figures 1a and 1b).
Before the beginning and the end of week 44, the fluxes of SARS-CoV-2 RNA in the wastewater treatment plants have:

  • decreased in some WWTPs (Beggen, Schifflange, Pétange, Bettembourg, Mersch, Troisvierges, Boevange-sur-Attert)
  • increasing in others (Bleesbruck,Hespérange, Übersyren, Grevenmacher, Echternach, Wiltz)

but remained in every WWTPs at high values indicating a still very high prevalence of the virus in the wastewater.
