Statement

The aim of this study was to adapt a protocol for amplifying and sequencing the complete SARS-CoV-2 genome, and to compare the diversity of variants observed following passive and grab sampling. Passive sampling and grab sampling of wastewater were carried out in parallel in the sewers of two French cities in April and May 2022, in regions with contrasting incidence rates. The devices were immersed for 24 hours at eleven sites, and sampling was repeated once at two-day intervals. The complete genome was amplified by ARTIC multiplex PCR and sequenced by Illumina MiSeq. Bioinformatics analysis was performed using the ASPICov pipeline. Sequencing of the SARS-CoV-2 genome from both types of sample showed that the circulating omicron variant sublineage BA2.1 was in the majority, and that sublineages B1.1, B.1.1.529, B.1.1.161 and BA.2.3 were poorly represented. Multiple mutations with varying frequencies were observed. The total number of reads and the percentage of mapped reads were similar for both sampling procedures. The protocol developed allowed the first sequencing of the SARS-CoV-2 genome in wastewater samples collected by passive sampling.
