Waste water monitoring in Luxembourg as part of SARS-CoV-2
According to the latest CORONASTEP report on the monitoring of SARS-CoV-2 in waste water in Luxembourg, prepared by the LIST (Luxembourg Institute of Science and Technology), it appears that the national level of SARS-CoV-2 contamination remains stable, with results that are very similar to those of week 37. However, a re-emergence of the SARS-CoV-2 signal has been detected in three wastewater treatment plants (Mersch, Uebersyren and Wiltz) with signals very close to the test's limit of detection. The geographical differences persist with the same four treatment plants (Pétange, Beggen, Schifflange and Bettembourg) being strongly impacted while the other treatment plants remain at a low level of contamination. The SARS-CoV-2 signal was not detectable in four (Echternach, Grevenmacher, Boevange-sur-Attert and Troisvierges) of the thirteen wastewater treatment plants.
