Abstract Background Central Michigan University (CMU) participated in a state-wide wastewater monitoring program starting 2021. One rural site consistently produced higher concentrations of SARS-CoV-2 genome copies. Samples from this were sequenced retrospectively and exclusively contained derivative Alpha variant lineage B.1.1.7 that shed the same for 20-28 months. Results Complete reconstruction each open reading frame (ORF) alignment to an early clinical isolate identified novel mutations selected non-structural (nsp1, nsp2, nsp3, nsp4, nsp5/3CLpro, nsp6, RdRp, nsp15, nsp16, ORF3a, ORF6, ORF7a, ORF7b) structural genes (Spike, M, N). These rare have not accumulated samples worldwide. Mutational analysis revealed divergence reference sequence over time. We present on available models discuss potential role these during chronic infection. Conclusions This study further supports small treatment plants can enhance resolution events facilitate viral genomes due relative lack contaminating sequences identifies may be associated with infections.

Aim: Wastewater-based epidemiology (WBE) is increasingly used to monitor pandemics. In this manuscript, we review methods and limitations of WBE, as well their online dashboards. Materials & methods: Online dashboards were retrieved using PubMed search engines, annotated for timeliness, availability English version, details on SARS-CoV-2 sublineages, normalization by population PPMoV load, case/hospitalization count charts raw data export. Results: We 51 web portals, half them from Europe. Africa represented South only, only seven portals are available Asia. Conclusion: WBS provides near-real-time cost-effective monitoring analytes across space time in populations. However, tremendous heterogeneity still persists the WBE literature.

Wastewater-based surveillance has emerged as an important method for monitoring SARS-CoV-2. This study investigated the presence of SARS-CoV-2 in wastewater Zambia. We conducted a longitudinal Copperbelt and Eastern provinces Zambia from October 2023 to December during which 155 samples were collected. The subjected three different concentration methods, namely bag-mediated filtration, skimmed milk flocculation, polythene glycol-based assays. Molecular detection nucleic acid was using real-time PCR. Whole genome sequencing Illumina COVIDSEQ assay. Of samples, 62 (40%) tested positive these, 13 sequences sufficient length determine lineages obtained two phylogenetically analyzed. Various Omicron subvariants detected including BA.5, XBB.1.45, BA.2.86, JN.1. Some these have been clinical cases Interestingly, phylogenetic analysis positioned sequence Province B.1.1.529 clade, suggesting that earlier variants late 2021 could still be circulating may not wholly replaced by newer subvariants. stresses need integrating into mainstream strategies circulation
