Description

Wastewater-based epidemiology (WBE) provides a global view as an effective tool for monitoring SARS-CoV-2. It primarily serves as an early detection system for COVID-19 outbreaks and offers the capacity to track viral spread within communities, including emerging variants. Authors discuss practical methodologies, existing challenges, and future potential of WBE in public health surveillance, highlighting its non-invasive nature and ability to detect both symptomatic and asymptomatic infections [1]. The evolution of WBE as a public health tool is evident, from its initial applications in detecting various community health indicators to its prominent role in monitoring SARS-CoV-2. This review summarizes the core principles, analytical techniques, and diverse applications, providing historical context while emphasizing its rapid development and increasing importance, particularly during the recent pandemic. WBE’s ability to offer a collective, unbiased snapshot of public health at a community level is a key benefit [3]. Complementing these insights, a year-long monitoring study of SARS-CoV-2 RNA in the wastewater of a Brazilian city correlated findings with clinical case data. This research demonstrated WBE's effectiveness in providing timely and complementary insights into the pandemic's progression. WBE data can serve as a leading indicator for clinical outbreaks, track community viral load, and potentially identify local transmission dynamics, offering valuable perspectives for future public health surveillance strategies beyond individual patient testing [8].

The application of WBE extends significantly to monitoring illicit drug use. In Brazil, its current state and future outlook specifically focus on this area, covering methodologies, detectable substances, and how data informs public health interventions and drug policy. Unique challenges and opportunities for WBE implementation in Brazil are discussed, stressing its potential to provide objective, real-time insights into community drug consumption patterns [2]. Similarly, in Spain, WBE reviews its application for monitoring community-wide usage of psychoactive substances. It details how WBE provides objective and timely data on drug consumption trends, complementing traditional survey-based methods. The utility of WBE in identifying spatial and temporal variations in substance use is critical for informing public health policies, targeted interventions, and resource allocation in prevention and treatment programs across different regions of Spain [5]. A comprehensive overview of WBE in monitoring illicit drugs and pharmaceuticals, with a focus on global trends, synthesizes current knowledge on analytical methods, biomarkers, and interpretation of WBE data to estimate population-level consumption. This highlights geographic and temporal patterns of substance use revealed worldwide, informing drug policy and public health interventions [9].

Beyond these specific applications, a broader perspective on WBE in public health applications outlines its present status and future directions. This includes core principles, analytical techniques, and a wide spectrum of applications, from monitoring infectious diseases to illicit drug use and environmental contaminants. Advancements have propelled WBE into a key tool for community health surveillance, with forecasts for its continued integration into broader public health strategies due to its unique advantages for non-invasive, population-level assessment [6]. Another crucial area is the application of WBE for monitoring pharmaceuticals and personal care products (PPCPs). This review summarizes methodologies for detecting a wide array of PPCPs in wastewater, assessing their environmental concentrations, and estimating community consumption patterns. WBE's ability to track the usage and environmental fate of these compounds, often not fully metabolized by humans, and discuss implications for environmental health and potential public health risks, calls for more standardized monitoring approaches [7].

Finally, WBE is critically evaluated for tracking environmental pollution indicators. It delves into methodologies used to detect and quantify various pollutants, including industrial chemicals, heavy metals, and emerging contaminants, in wastewater. WBE's capacity to serve as an early warning system for environmental contamination, assess the effectiveness of pollution control measures, and inform environmental policy is emphasized. Limitations and future directions for enhancing WBE's role in comprehensive environmental management and public health protection are also addressed [10]. However, implementing and scaling WBE programs faces significant challenges, particularly in low- and middle-income countries (LMICs), as highlighted by a global perspective. Disparities in infrastructure, funding, technical expertise, and political will hinder WBE's full potential. Strategies such as tailored approaches and international collaborations are proposed to overcome these barriers, advocating for considerations of unique socio-economic and environmental contexts to strengthen global health surveillance [4].

Conclusion

Wastewater-based epidemiology (WBE) is emerging as a critical tool for public health surveillance, offering a non-invasive and objective approach to monitoring community health. It has demonstrated significant utility in tracking the spread of infectious diseases, notably SARS-CoV-2, by serving as an early detection system for outbreaks and identifying emerging variants within communities. Beyond pathogen surveillance, WBE provides real-time insights into population-level illicit drug consumption patterns, aiding in public health interventions and drug policy formulation. The technique also extends to monitoring pharmaceuticals, personal care products, and environmental pollution indicators, assessing their usage, environmental concentrations, and potential health risks. This field has seen rapid development, with various reviews outlining its core principles, analytical techniques, and diverse applications, from historical contexts to its current prominent role. Studies highlight its ability to offer an unbiased snapshot of public health, complementing traditional survey-based methods. While offering immense potential globally, especially in low- and middle-income countries (LMICs), WBE implementation faces challenges related to infrastructure, funding, and technical expertise. Addressing these barriers through tailored approaches and international collaborations is crucial for strengthening global health surveillance. Researchers continue to explore WBE's future directions, forecasting its deeper integration into broader public health strategies for comprehensive community-level assessment.
