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

The CORONASTEP 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 47th and 48th week of 2022 shows a high prevalence of SARS-CoV-2 in wastewater. The situation regarding the contamination level of the waste water seems to be quite stable compared to the previous two weeks, although a very slight upward trend could be observed from week 47 onwards. The next results will be essential to know if this trend is confirmed.

All CORONASTEP reports are available on the LIST website:
