Since the COVID-19 pandemic, a decrease in prevalence of Influenza A virus (IAV) and respiratory syncytial (RSV) has been suggested by clinical surveillance. However, there may be potential biases obtaining an accurate overview infectious diseases community. To elucidate impact on IAV RSV, we quantified RSV RNA wastewater collected from three treatment plants (WWTPs) Sapporo, Japan, between October 2018 January 2023, using highly sensitive EPISENS™ method. From to April 2020, M gene concentrations were positively correlated with confirmed cases corresponding area (Spearman's r = 0.61). Subtype-specific HA genes also detected, their showed trends that consistent clinically reported cases. B serotypes detected wastewater, 0.36-0.52). The detection ratios decreased 66.7 % (22/33) 42.4 (14/33) 4.56 (12/263) 32.7 (86/263), respectively city after prevalence. present study demonstrates usefulness wastewater-based epidemiology combined preservation (wastewater banking) as tool for better management viral diseases.

Wastewater-based epidemiology (WBE) is a promising approach for monitoring the spread of SARS-CoV-2 within communities. Although qPCR-based WBE powerful in that it allows quick and highly sensitive detection this virus, can provide limited information about which variants are responsible overall increase or decrease virus sewage, hinders accurate risk assessments. To resolve problem, we developed next generation sequencing (NGS)-based method to determine identity composition individual wastewater samples. Combination optimization targeted amplicon-sequencing nested PCR allowed each variant with sensitivity comparable qPCR. In addition, by targeting receptor binding domain (RBD) S protein, has mutations informative classification, could discriminate most concern (VOC) even sublineages Omicron (BA.1, BA.2, BA.4/5, BA.2.75, BQ.1.1 XBB.1). Focusing on benefit decreasing reads. We applied samples collected from treatment plant Kyoto city throughout 13 months (from January 2021 February 2022) successfully identified lineages wild-type, alpha, delta, omicron BA.1 BA.2 as well their compositions The transition these was good agreement epidemic situation reported during period based clinical testing. These data indicate our NGS-based useful detecting tracking emerging sewage Coupled advantages WBE, potential serve an efficient low cost means community assessment infection.

Background Wastewater surveillance has expanded globally as a means to monitor spread of infectious diseases. An inherent challenge is substantial noise and bias in wastewater data because the sampling quantification process, limiting applicability monitoring tool. Aim To present an analytical framework for capturing growth trend circulating infections from conducting scenario analyses guide policy decisions. Methods We developed mathematical model translating observed SARS-CoV-2 viral load into effective reproduction numbers. used extended Kalman filter infer underlying transmissions by smoothing out observational noise. also illustrated impact different countermeasures such vaccinations non-pharmaceutical interventions on projected number cases using three study areas Japan during 2021–22 example. Results Observed notified were matched with range estimated our approach only, across virus methods, especially when disease prevalence was high. Estimated numbers derived consistent notification-based Our projections showed that 10–20% increase vaccination coverage or 10% reduction contact rate may suffice initiate declining areas. Conclusion demonstrates how can be track perform modelling inform The proposed complements conventional clinical surveillance, reliable timely epidemiological are not available.
