Wastewater monitoring in Luxembourg as part of SARS-CoV-2

The CORONA STEP report is published every 15 days.

According to the latest CORONASTEP report drawn up by the LIST (Luxembourg Institute of Science and Technology), the contamination level of the 13 wastewater treatment plants analysed during the 33th and 34th week of 2022 still shows a high prevalence of SARS-CoV-2 in wastewater at national level. The downward trend observed during the last two weeks (weeks 31 and 32) continues and the level of SARS-CoV-2 contamination in wastewater continues to decrease, both nationally and regionally, and may soon reach an average level. All CORONASTEP reports are available on the LIST website:
