Mapping Vulnerability in Pandemic Response: Optimizing Wastewater Epidemiology with Geospatial Intelligence Heading link

WBE initiative

Wednesday, January 24, 2024
12:00 pm – 1:00 pm

Wastewater-Based Epidemiology (WBE) has become an essential public health tool, particularly critical in times when traditional clinical testing is limited. The Illinois Wastewater Surveillance System (IWSS), one of the largest WBE initiatives in the USA, plays a vital role in public health monitoring. It achieves this by continuously monitoring ~ 80 wastewater treatment plants (WWTPs) across the state, tracking infection rates and identifying variant trends of diseases like COVID-19, influenza, and RSV at the community level. This presentation will discuss the vulnerability-driven site selection strategy developed for the Illinois WBE program. This strategy is fundamental to the program’s ability to deliver comprehensive and equitable public health surveillance throughout Illinois. We will delve into the development of this strategic site selection methodology, which melds epidemiological modeling with machine learning algorithms within a geospatial framework. This innovative approach not only enhances the accuracy of public health surveillance but also ensures the equitable representation of diverse urban and rural communities across the state.
