Publications

The publications on this page showcase the core scientific and implementation work of the Public Health Alliance for Genomic Epidemiology (PHA4GE). Together, they highlight how PHA4GE develops and shares open standards, tools, data models, and guidance to support genomic epidemiology and public health practice around the world.

Wastewater metagenomics is transforming how we monitor microbial communities, offering a powerful and cost-effective approach for pathogen surveillance, antimicrobial resistance (AMR) tracking, and environmental health insights. In Africa, high-throughput sequencing (HTS) of wastewater can serve as an early warning system for infectious disease outbreaks—especially in densely populated areas with limited sanitation—while also supporting discovery of emerging pathogens and novel microbial functions. This overview highlights both the major opportunities and the key challenges, including infrastructure limitations, bioinformatics capacity gaps, variable wastewater composition, and data governance considerations, and outlines the collaborations and investments needed to unlock equitable public health and economic benefits.

During the 2022 and 2024 global Mpox outbreaks, a standardized contextual data specification was developed to support public health genomic surveillance of MPXV. The specification defines ontology-based fields and controlled vocabularies for harmonized capture of sample metadata, epidemiological, clinical, laboratory, and methodological information, with emphasis on geo-temporal context, data provenance, and sampling strategy. Implemented within the open-source DataHarmonizer platform, the MPXV specification enables structured curation, validation, and transformation of surveillance data and is currently in use in Canada, with international applicability and extensibility to other pathogens.

This publication presents the PHA4GE wastewater contextual data specification, an ISO-compatible, ontology-based standard developed with global partners to support interoperable wastewater genomic surveillance. Implemented through open-source tools and shared frameworks, the specification enables harmonised data integration and serves as a model for broader environmental and metagenomic surveillance standards.

Guidance Documents & Standards

PHA4GE develops guidance documents, standards, and best-practice resources to support the effective use of genomics in public health. These outputs are created through collaborative working groups and reflect consensus-driven, evidence-based approaches informed by global public health practice.

In the Media

PHA4GE’s work in public health genomics and global disease surveillance has been featured in international media, specialist publications, and sector-focused outlets. These independent mentions reflect growing recognition of the importance of coordinated, data-driven approaches to strengthening global public health systems.

This piece highlights Pathoplexus, a community-driven viral genomics database developed with input from PHA4GE to advance open data sharing, ethical use, and transparent governance in public health genomics.

From COVID-19 to measles, scientists are showing how wastewater surveillance can expose underreported infections and strengthen national health monitoring.

More than 270 scientists, policy-makers, funders and public health experts from around the world attended the third International Pathogen Surveillance Network (IPSN) Global Partners Forum in Cape Town, South Africa from 27 to 29 October 2025. The forum was held jointly with the second Public Health Alliance for Genomic Epidemiology (PHA4GE) biennial conference and was co-hosted by the WHO Hub for Pandemic and Epidemic Intelligence and WHO’s Regional Office for Africa

Conferences

PHA4GE hosts a biennial international conference that brings together the global public health genomics community to share knowledge, align on standards, and advance the use of genomic epidemiology for public health action.

More than 270 scientists, policy-makers, funders, and public health experts from around the world gathered in Cape Town for the third International Pathogen Surveillance Network Global Partners Forum, held jointly with PHA4GE’s second biennial conference. Under the theme Data for Action, the meeting focused on translating genomics into public health impact through stronger surveillance systems, digital infrastructure, and equitable global data sharing.

PHA4GE’s first-ever conference took place from 30 October to 1 November 2023 at Cavalli Estate in Cape Town, South Africa, bringing together the global public health genomics community. The meeting explored key topics including pathogen surveillance tools, data harmonisation, laboratory quality assurance, ethical data sharing, and enabling genomics in resource-limited settings.
