To inform the development of global wastewater monitoring systems, we surveyed programmes in 43 countries. Most monitored predominantly urban populations. In high-income countries (HICs), composite sampling at centralised treatment plants was most common, whereas grab from surface waters, open drains, and pit latrines more typical low-income middle-income (LMICs). Almost all analysed samples in-country, with an average processing time 2·3 days HICs 4·5 LMICs. Whereas 59% regularly for SARS-CoV-2 variants, only 13% LMICs did so. share their data internally, partnering organisations, but not publicly. Our findings show richness existing ecosystem. With additional leadership, funding, implementation frameworks, thousands individual initiatives can coalesce into integrated, sustainable network disease surveillance-one that minimises risk overlooking future health threats.

Much of what is known and theorized concerning passive sampling techniques has been developed considering chemical analytes.

Wastewater-based epidemiology (WBE) has been widely used to track levels of SARS-CoV-2 infection in the community during COVID-19 pandemic. Due rapid expansion WBE, many methods have and developed for virus concentration detection wastewater. However, very little information is available on relative performance these approaches. In this study, we compared five commonly wastewater quantification pathogenic viruses (SARS-CoV-2, norovirus, rotavirus, influenza, measles viruses), fecal indicator (crAssphage, adenovirus, pepper mild mottle virus), process control (murine norovirus bacteriophage Phi6) laboratory spiking experiments. The evaluated included those based either ultrafiltration (Amicon centrifugation units InnovaPrep device) or precipitation (using polyethylene glycol [PEG], beef extract-enhanced PEG, ammonium sulfate). two best were further tested 115 unspiked samples.

The first step in SARS-CoV-2 genomic surveillance is testing to identify people who are infected. However, global rates falling as we emerge from the acute health emergency and remain low many low- middle-income countries (mean = 27 tests per 100,000 day).

Abstract During the COVID-19 pandemic, wastewater-based epidemiology (WBE) and clinical surveillance have been used as tools for analyzing circulation of SARS-CoV-2 in community, but both approaches can be strongly influenced by some sources variability. From challenging perspective integrating environmental data, we performed a correlation analysis between concentrations raw sewage incident cases areas served medium-size wastewater treatment plants (WWTPs) from 2021 to 2023. To this aim, datasets were adjusted several variability: WBE data factors including analytical protocol, flow, population size, while adjustments considered demographic composition population.

Wastewater-based epidemiology has emerged as a powerful public health tool to trace new outbreaks, detect trends in infection, and provide an early warning of COVID-19 community spread. Here, we investigated the spread SARS-CoV-2 infections across Utah by characterizing lineages mutations detected wastewater samples. We sequenced over 1,200 samples from 32 sewersheds collected between November 2021 March 2022. Wastewater sequencing confirmed presence Omicron (B.1.1.529) on 19, 2021, up 10 days before its corresponding detection via clinical sequencing. Analysis diversity revealed Delta most frequently lineage during (67.71%), but it started declining December with onset (B.1.1529) sublineage BA.1 (6.79%).
