Wastewater Surveillance Guidance and Resources

This repository hosts guidance documents and resources developed by the PHA4GE Wastewater Surveillance Working Group. These documents address core challenges involved in designing effective wastewater surveillance strategies, analyzing wastewater pathogen sequencing and quantification data, and sharing this data with the global public health community.

The PHA4GE Wastewater Contextual Data Specification

The PHA4GE Wastewater Contextual Data Specification Package is scoped for data collection and sharing (within organizations, within networks and if desired, with public repositories) of both pathogen-agnostic genomics contextual data and genotypic attributes (such as antimicrobial resistance genes) derived from amplicon-based, WGS, and metagenomic sequencing approaches. The goal of the specification is to create a data interoperability framework that enables exchange and communication between data generators and consumers using wastewater for surveillance, that is extensible for other types of water-based surveillance (e.g. agriculture-based water monitoring, freshwater and marine environmental studies, and wildlife vector investigations), and is compatible with existing clinical and One Health standards. The specification was designed through consultation with partners involved in different wastewater projects in LMICs and HICs.

PHA4GE kicked off work on malaria genomics data standards at ASTMH 2024 in New Orleans, where Alan Christoffels and Tracey Calvert-Joshua presented a funding proposal on metadata collection.

A look into how PHA4GE is creating a set of development guides, as well as a database of searchable attributes enabling the assembly of suites for specific use cases and ensuring that relevant terms are re-used, increasing interoperability across the data streams in public health

Wastewater surveillance is a crucial public health tool that involves monitoring the contents of wastewater to gain insights into community health. This method can detect the spread of infectious diseases, track drug use patterns, and assess the effectiveness of public health measures. By analyzing wastewater, health officials can identify outbreaks early, observe disease trends, and allocate resources more effectively, ultimately safeguarding public health.
