Genomic pathogen surveillance (service)

Genomic pathogen surveillance sequences pathogen genomes at scale to track viral and bacterial evolution, detect emerging variants and map transmission chains, feeding public health response decisions faster than case-count reporting alone. Ginkgo Bioworks’ Concentric platform runs the CDC’s Traveler-based Genomic Surveillance Program, sequencing pooled nasal-swab and wastewater samples from international travelers, and has expanded to new US airports including Miami and Chicago while partnering with Illumina to deploy biosurveillance technology globally, including a Rwanda government partnership. Oxford Nanopore Technologies’ portable MinION sequencers enable real-time field sequencing during outbreaks — its published workflow for Mpox virus sequencing is one current example of a technology previously deployed during Ebola and COVID-19 outbreak response. The Wellcome Sanger Institute runs the UK’s National Metagenomic Pathogen Surveillance Programme in partnership with the UK Health Security Agency (UKHSA), sharing initial surveillance data at the European Congress of Clinical Microbiology and Infectious Diseases (ESCMID). BGI Genomics operates large-scale pathogen genomic sequencing infrastructure in China, built out during the COVID-19 pandemic and continuing as part of the country’s infectious-disease response capacity. In India, the Rajiv Gandhi Centre for Biotechnology has been selected as the national next-generation-sequencing hub for metagenomic syndromic surveillance.

The key directions of genomic pathogen surveillance are:

1. Traveler-based genomic biosurveillance (Traveler-Based Genomic Surveillance): sequencing pooled samples from international travelers or at border points to detect emerging variants before they’re identified through clinical case reporting — Ginkgo Bioworks’ Concentric, the CDC airport program.
2. Portable field sequencing (Portable Genomic Sequencing): compact sequencers deployed directly at outbreak sites for real-time genomic data without shipping samples to a central lab — Oxford Nanopore Technologies.
3. National metagenomic surveillance programs (Metagenomic Pathogen Surveillance): government-partnered sequencing programs providing standing pathogen-genomics infrastructure for a country’s public health system — Wellcome Sanger Institute/UKHSA, Rajiv Gandhi Centre for Biotechnology.
4. Large-scale sequencing infrastructure (Genomic Surveillance Infrastructure): high-throughput national sequencing capacity built for pandemic response and sustained as ongoing surveillance capability — BGI Genomics.

Cross-cutting technologies of the sector:

• Traveler-based biosurveillance (Traveler-Based Genomic Surveillance): pooled sampling at international travel hubs catches emerging variants circulating abroad before they appear in domestic clinical case data.
• Portable nanopore sequencing (Portable Genomic Sequencing): compact, field-deployable sequencers generate genomic data at the outbreak site itself, cutting the turnaround time a central-lab shipping step would add.
• National metagenomic infrastructure (Metagenomic Pathogen Surveillance): standing government-partnered sequencing hubs provide continuous pathogen-genomics capacity rather than one-off pandemic-response mobilization.

The stack pairs sequencing hardware (portable and centralized) with bioinformatics lineage-calling pipelines and public-health reporting workflows, converting raw genomic data into an actionable surveillance signal.

1. Traveler-based biosurveillance (Traveler-Based Genomic Surveillance):
   • Ginkgo Bioworks’ Concentric platform pools nasal-swab and wastewater samples from international travelers at airport sites, sequencing them to detect variants circulating abroad before they surface in domestic clinical case data, now expanded to additional US international airports.
2. Portable field sequencing (Portable Genomic Sequencing):
   • Oxford Nanopore Technologies’ MinION devices generate genomic sequence data directly at an outbreak site, with published workflows (including for Mpox) supporting rapid field deployment without shipping samples to a central lab.
3. National metagenomic surveillance infrastructure (Metagenomic Pathogen Surveillance):
   • The Wellcome Sanger Institute/UKHSA partnership and the Rajiv Gandhi Centre for Biotechnology’s designation as India’s national NGS hub both build standing, government-partnered sequencing capacity rather than one-off pandemic mobilization.
4. Large-scale sequencing infrastructure (Genomic Surveillance Infrastructure):
   • BGI Genomics’ pandemic-scale sequencing capacity, built out during COVID-19, continues as part of China’s ongoing infectious-disease genomic-surveillance capability.
