NCT05041764

Brief Summary

The aim is to compare the percentage of the different SARS-CoV2 lineages that are detected in wastewater samples with matched clinical samples. About 1,400 swab samples from patients living in Nice were tested by Biogroup between Oct 19th and Oct 23rd (Week 43 of 2020). The sequence of 81 PCR positive samples, corresponding to all samples that were unambiguously assigned to one of the wastewater catchment areas and their lineage was determined. These values were compared to values measured in wastewater.
