Description

Wastewater-based epidemiology (WBE) has emerged as an exceptionally effective tool for widespread infectious disease surveillance, offering a cost-effective and population-wide approach to monitoring public health [8]. This non-invasive method provides community-level insights into pathogen circulation, often detecting trends before clinical cases become widely apparent [3]. WBE's utility spans across various public health challenges, emphasizing its crucial role in tracking disease spread and informing targeted public health responses, particularly vital during outbreaks and pandemics [1, 8]. The ability to gather comprehensive data from a single point of collection makes it a powerful sentinel system for community health [3].

The application of WBE has been particularly prominent in tracking viral pathogens. For instance, a global overview highlighted its crucial role in monitoring SARS-CoV-2, exploring diverse methodological approaches and showcasing successful applications in public health surveillance during the pandemic [1]. Beyond SARS-CoV-2, WBE is instrumental for the early detection and ongoing surveillance of other emerging viral pathogens, where wastewater systems serve as critical sentinels [3]. Surveillance efforts also extend to specific viruses like influenza, providing a comprehensive review of methods, findings, and implications for tracking seasonal dynamics and detecting novel strains, serving as an early warning system for respiratory outbreaks [4]. Critical reviews have also evaluated wastewater surveillance for poliovirus and other enteroviruses, recognizing its efficacy in detecting silent circulation, which is essential for global eradication efforts and broader enteric pathogen monitoring [7]. Furthermore, norovirus wastewater surveillance provides timely data on circulation, aiding in outbreak detection and informing interventions for this highly contagious gastrointestinal pathogen [9].

Wastewater monitoring is equally significant in addressing bacterial threats, especially the growing concern of antimicrobial resistance (AMR). Systematic reviews have assessed WBE for monitoring various bacterial pathogens, synthesizing findings on detection methods and the utility of wastewater data for understanding community-level pathogen prevalence and distribution [5]. This technique also delves into wastewater surveillance for antimicrobial resistance genes (ARGs), discussing key methodological considerations for accurate detection and quantification. Such monitoring offers a comprehensive picture of community-level AMR trends, aiding in the development of effective mitigation strategies [2]. This work further explores the current state and future potential of using WBE to track antimicrobial resistance within communities, providing crucial, non-invasive insights into the circulation of resistance genes, which is vital for responding to this critical public health challenge [6].

Despite the demonstrated effectiveness, the field of WBE continues to evolve with ongoing research into methodologies and the addressing of inherent challenges. Discussions around methodological considerations are crucial for ensuring accurate and reliable detection and quantification across different pathogen types [2, 4]. The current progress in WBE highlights its potential as a robust tool, yet future challenges include standardizing methods, improving sensitivity, and expanding its reach to diverse communities [8]. Researchers are continuously refining techniques and exploring new applications, ensuring that WBE remains at the forefront of public health monitoring.

Looking ahead, wastewater surveillance is expanding into new frontiers, notably the emerging field of fungal pathogens. This innovative area positions WBE as a new approach in public health, outlining methodologies, potential targets, and the utility of detecting fungi in wastewater. Such efforts promise to contribute to a deeper understanding of environmental health risks and the overall burden of disease within populations, marking a significant development in the broader application of wastewater epidemiology [10]. The continuous exploration of novel targets reinforces WBE's adaptability and expanding role in comprehensive public health surveillance.

Conclusion

Wastewater-based epidemiology (WBE) provides a powerful, non-invasive approach to public health surveillance. The collected research highlights its global utility, notably in monitoring SARS-CoV-2 during pandemics by exploring methodological approaches and successful applications for tracking viral spread and informing public health responses. WBE is crucial for early detection and surveillance of emerging viral pathogens, acting as a critical sentinel system that offers community-wide insights before clinical cases surge. This surveillance extends to specific viral threats like influenza, tracking seasonal dynamics and detecting novel strains as an early warning system for respiratory outbreaks. It also critically evaluates poliovirus and other enterovirus surveillance, essential for eradication efforts and broader enteric pathogen monitoring. Beyond viruses, WBE is vital for assessing antimicrobial resistance genes, discussing detection methodologies and their applications in understanding community-level resistance trends. Furthermore, it covers the monitoring of various bacterial pathogens, synthesizing findings on detection methods and pathogen prevalence. The field is continuously evolving, detailing current progress and challenges while exploring new frontiers, such as wastewater surveillance for fungal pathogens, which promises to enhance understanding of environmental health risks and disease burdens within communities.
