CORONASTEP Report 28 SARS-CoV-2 Sewage Surveillance in Luxembourg

Vers le niveau supérieur

This report 28 presents the results of SARS-CoV-2 contamination of wastewater at the inlet of 13 wastewater
treatment plants (WWTPs) obtained during the week 48. Three distinct sampling dates were analysed, excepted
for the Hespérange and Boevange-sur-Attert wastewater treatment plants.
During week 48, the level of contamination remains for all wastewater treatment plants analysed at high
values of SARS-CoV-2 fluxes, indicating a still high prevalence of the virus in wastewater, higher than this
of the first wave (Figures 1a and 1b). However, the data collected this week seems to validate the downward
trend observed last week, although it is still weak. This trend must be interpreted with caution and will have to
be confirmed in the coming days or weeks.
At the scale of the treatment plants, the RNA flows of SARS-CoV-2 still show sawtooth variations on a weekly
basis. However, a downward trend in comparison with previous weeks can also be observed for all the
wastewater treatment plants studied individually.
