This report 55 presents the results of SARS-CoV-2 contamination of wastewater at the entrance of the 12 wastewater treatment plants at the very beginning of the week 10 of 2021. The flux of SARS-CoV-2 RNA present in wastewater treatment plants at the early beginning of the week 10 indicates a still high prevalence of the virus in wastewater at the national level, with, however, a continuing downward trend. Next week's sampling will confirm or not the observed dynamics.
A comparable downward trend was also observed overall at the various wastewater treatment plants.
