In recent years, wastewater-based epidemiology (WBE) has emerged as a valuable and cost-effective tool for monitoring the prevalence of COVID-19. Large-scale efforts have been implemented in numerous countries, primarily focusing on sampling at entrance wastewater treatment plants (WWTPs) to cover large population. However, finer spatial scale, such neighborhood level (NGBs), pose new challenges, including absence composite infrastructure increased uncertainty due dynamics small catchments. This study aims investigate feasibility accuracy WBE when deployed (sampling sewers) compared city WWTP). To achieve this, we specific stations intraurban scale within three NGBs Barcelona, Spain. The period covers 5th 6th waves COVID-19 Spain, spanning from March 2021 2022, along with WWTP downstream NGBs. results showed strong correlation between clinical cases SARS-CoV-2 loads both NGB levels.

Interestingly, did not exhibit major differences among different socioeconomic statuses.

Wastewater-based epidemiology (WBE) is an effective, non-invasive method for monitoring the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by tracking viral prevalence in water. This study aimed to investigate presence SARS-CoV-2 surface water Vietnam over two years. One-step quantitative reverse transcription polymerase chain reaction (qRT-PCR) assays were employed quantify and its variant-specific mutation sites (G339D/E484A) pepper mild mottle virus (PMMoV) from a total 315 samples (105 per type) compare with reported Coronavirus disease 2019 (COVID-19) cases environmental factors. was detected 38 % (40/105), 43 (45/105), 39 (41/105) Sites A, B, C, respectively, concentrations 3.0-5.6 log

Abstract During the COVID-19 pandemic, wastewater monitoring has been used to monitor levels of SARS-CoV-2 RNA entering sewerage system. In Italy, Istituto Superiore di Sanità coordinated SARI project (Sorveglianza Ambientale Reflue in Italia) detect and its variants. this study, concentration variants raw against cases was evaluated together with effect temperature precipitation on virus spread. We validated a predictive model, proposed by De Giglio et al., 2021, establish number cases/100,000 inhabitants. A receiver operating characteristic curve model applied predict Poisson regression study rainfall viral load. Apulia, from October 2021 December 2022, we analyzed 1041 samples, which 985 (94.6%) tested positive for SARS-CoV-2. Median atmospheric inversely proportional load wastewater; no correlation found precipitation. The confirmed that at least 11 inhabitants would occur 15 days following detection wastewater.

Wastewater-based epidemiology provides an approach for assessing the prevalence of COVID-19 in a sewer service area. In this study, SARS-CoV-2 RNA was measured 44 wastewater-treatment plants varying sizes that sampled approximately 67% population Minnesota, from September 2020 through December 2022. Various linear regression models were investigated to predict weekly case count concentrations under various transformation and normalization methods which we validated via cross-validation averaged across all treatment plants. We find relationship between incidence wastewater may be plant-specific. study storage time-to-analysis data large effects temperature, indicating collection have important effect on utility validity infectious disease monitoring. Our findings are any large-scale surveillance program.

Background Testing samples of waste water for markers infectious disease became a widespread method surveillance during the COVID-19 pandemic. While these data generally correlate well with other indicators national prevalence, that cover localised regions tend to be highly variable over short time scales. Methods We introduce procedure estimating realtime growth rate pathogen prevalence using series from wastewater sampling. The number copies target gene found in sample is modelled as time-dependent random whose distribution estimated maximum likelihood. output depends on hyperparameter controls sensitivity variability underlying data. apply this reporting N1 SARS-CoV-2 collected at treatment works across Scotland between February 2021 and 2023. Results real-time 121 sampling sites covering diverse range locations population sizes. find fitting natural determines its reliability detecting early stages an epidemic wave. Applying hospital admissions data, we changes are detected average 2 days earlier than Conclusion provide robust generate reliable estimates provides responsive situational awareness inform public health.
