Waste water monitoring in Luxembourg as part of SARS-CoV-2

The latest CORONASTEP report drawn up by the LIST (Luxembourg Institute of Science and Technology), indicates that during the week of 30 November to 6 December, SARS-CoV-2 flows in wastewater remain high. However, the latest data collected, particularly at the end of the week in question, confirmed the downward trend observed in previous weeks. This trend will have to be confirmed in the coming days or weeks.
