Wastewater-Based Epidemiology; Emerging trends in monitoring pathogens (i.e., viruses) and chemicals

By analysing wastewater, we can detect and monitor the spread of various pathogens and viruses, providing invaluable insights that complement traditional epidemiological approaches.

We begin by introducing the concept of Wastewater-Based Epidemiology, delving into its scientific underpinnings and the methodologies employed to detect pathogens and viruses in wastewater. This approach has evolved significantly, with its roots tracing back to monitoring polio virus, and it has gained substantial traction in recent years, particularly highlighted by its role in tracking the spread of SARS-CoV-2.

The process of WBE involves a series of intricate steps, starting from the collection of wastewater samples to the advanced analytical techniques used to interpret the data. These methods are crucial for translating raw data into meaningful epidemiological information that can guide public health decisions. Through various case studies, we'll examine how WBE has been applied globally to track a range of pathogens, showcasing its versatility and impact. We'll explore the diverse array of pathogens and viruses that can be detected in wastewater, discussing how they behave and persist in the sewerage system. Environmental factors play a significant role in the survival and detection of these microorganisms, influencing the accuracy and reliability of WBE data.

Interpreting data from wastewater is a complex but crucial aspect of WBE. We'll delve into how this information is used to predict and respond to outbreaks, integrating WBE findings with traditional epidemiological data to provide a comprehensive view of public health trends. The session will also highlight the latest technological advancements and innovations in the field, which are set to further enhance the capabilities of WBE.

Despite its potential, WBE faces several challenges, from analytical difficulties to ethical considerations. Addressing these challenges is essential for the effective implementation and acceptance of WBE as a tool in public health. We'll discuss the importance of infrastructure, resources, and collaboration among stakeholders in overcoming these hurdles.

The implications of WBE extend beyond data collection, influencing public health policies and interventions. By examining how WBE data has shaped responses to events like the COVID-19 pandemic, we'll gain insights into its potential to inform future public health strategies.
