During the COVID-19 pandemic, measurement of SARS-CoV-2 RNA levels in wastewater quickly emerged as an additional tool for monitoring and to provide early warning system. This led development several regional, national international projects aimed at applying this approach. The main principle is based on detection viral signature untreated indication infection within connected populations. However, concentration can be impacted by dilution factors or population changes sewer shed, leading misinterpretation results. Therefore, there need normalization ensure accurate representation numbers. aim study was evaluate different bacterial markers their efficiency normalizing WBE data, which will enhance accuracy when interpreting concentrations wastewater. Weekly sampling conducted from two treatment plants (WWTP A WWTP B) eThekwini district over a period three months (July-October 2022). Three biomarkers (crAssphage, Bacteroides (HF 183), Pepper Mild Motile Virus) where chosen ascertain most suitable data normalization. Biomarker SARS CoV-2 samples were determined using droplet digital PCR (ddPCR). Physicochemical characteristics also identify potential impact these biomarkers. To determine biomarker, correlation analysis Adaptive neuro fuzzy inference system (ANFIS) model used. Average sampled WWTPs ranged 0.28 copies/µL 9.57 copies/µL.

A focus on water quality has intensified globally, considering its critical role in sustaining life and ecosystems. Wastewater, reflecting societal development, profoundly impacts public health. Wastewater-based epidemiology (WBE) emerged as a surveillance tool for detecting outbreaks early, monitoring infectious disease trends, providing real-time insights, particularly vulnerable communities. WBE aids tracking pathogens, including viruses, sewage, offering comprehensive understanding of community health lifestyle habits. With the rise global COVID-19 cases, gained prominence, aiding SARS-CoV-2 levels worldwide. Despite advancements treatment, poorly treated wastewater discharge remains threat, amplifying spread water-, sanitation-, hygiene (WaSH)-related diseases. WBE, serving complementary surveillance, is pivotal community-level viral infections. However, there untapped potential to expand surveillance. This review emphasizes importance link between health, highlighting need further integration into management.

By tracking infectious diseases through sewage, municipal-scale wastewater surveillance has provided early warnings of future COVID-19 hospitalisations, identified biases in diagnostic testing, and is rapidly expanding to a broader array pathogens. Despite applications the targeted delivery local interventions, near-source received less attention we know little about time series dynamics contrasting To address this, conducted at five sites for SARS-CoV-2 two norovirus GI, GII, influenza A virus, B human respiratory syncytial virus (RSV RSV B). Sites were selected functions: an office, charity centre, museum, university, care home. The key findings are (1) detections linked events (staff sickness, enhanced cleaning, changing populations); (2) decreased order GII > GI ≈ B; (3) correlation between data national increases as function catchment size viral prevalence (examples include BA.4/BA.5 variant peak museum winter season); (4) strong weekday periodicity detections, with against case numbers increasing when modelling variable lag times faecal shedding onset clinical diagnosis (R 2 = 0.45 0.84-0.86); (5) log-linear relationship frequency detection log(catchment size⋅viral prevalence) 0.6914-0.9066). Finally, propose use cases. Firstly, rare or high-risk pathogens, sentinel systems provide warning outbreaks, achieving high community coverage without behaviour change low cost versus testing.
