A consensus or society position rather than new primary data.
This is a narrative review of wastewater-based epidemiology (WBE) as a surveillance methodology for detecting viral pathogens in populations. The source describes WBE's principles, advantages (non-invasive, community-level, captures asymptomatic individuals), known challenges (variability in composition, RNA degradation, need for standardization), and successful application during COVID-19, but does not present original comparative data or quantified diagnostic performance.
Journal article. Populations shedding viral pathogens in excreta, including both symptomatic and asymptomatic individuals; emphasis on applicability in low-resource settings..
WBE enables early detection and surveillance of pathogens including Rotavirus, Astrovirus, Adenovirus, Sapovirus, poliovirus, and noroviruses. WBE was successfully used as an early warning system during the COVID-19 pandemic to predict outbreaks and guide public health interventions. Molecular techniques including PCR and genomic sequencing have enhanced sensitivity and specificity of viral detection in wastewater samples.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
WBE is presented as a complementary surveillance tool for public health authorities to monitor disease trends and support timely outbreak response, particularly where individual testing capacity is limited. Clinicians should understand WBE as a population-level epidemiological signal, not a diagnostic test for individual patients.

What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Wastewater-based epidemiology (WBE) has emerged as a powerful and cost-effective approach for monitoring the spread of viral diseases within populations. By analyzing wastewater for viral genetic material shed in human excreta, WBE enables the early detection and surveillance of pathogens such as Rotavirus, Astrovirus, Adenovirus, Sapovirus, poliovirus, and noroviruses. This method provides a non-invasive, community-level assessment of infection trends, capturing data from both symptomatic and asymptomatic individuals. Despite its advantages, challenges such as variability in wastewater composition, environmental degradation of viral RNA, and the need for standardized protocols remain. Nevertheless, WBE holds significant promise as a complementary surveillance tool, particularly in low-resource settings, enabling timely responses to emerging and re-emerging viral threats. WBE gained global prominence during the COVID-19 pandemic, where it was successfully used as an early warning system to predict outbreaks and guide public health interventions. Advances in molecular techniques, including PCR and genomic sequencing, have enhanced the sensitivity and specificity of viral detection in wastewater samples. Wastewater-based epidemiology represents an innovative and scalable strategy for public health monitoring, offering valuable insights into population-level disease dynamics and supporting proactive disease control measures.
