Avian Influenza Genomic Surveillance

WINGS

Wild-bird Influenza Genomics and Surveillance

About WINGS

WINGS is a portable Snakemake workflow for genomic characterization, bioinformatics analysis, and surveillance of avian influenza A viruses from wild-bird samples sequenced using Oxford Nanopore technologies.

The workflow integrates read preprocessing, influenza assembly, segment-level quality assessment, consensus polishing, variant calling, subtype screening, genotype assignment, annotation, and interactive reporting to support genomic epidemiology and wildlife disease surveillance.

Pipeline capabilities

Nanopore sequencing

Processes Oxford Nanopore reads for influenza A genomic analysis.

Genome assembly

Uses CDC IRMA for influenza genome assembly and segment recovery.

Genomic characterization

Performs consensus polishing, variant analysis, subtype screening, genotype assignment, and sequence annotation.

Surveillance reporting

Generates sample-level and sequencing-run HTML reports for reviewing genomic surveillance results.

Genomic epidemiology and surveillance

WINGS was designed to support genomic epidemiology of avian influenza viruses detected through surveillance of wild birds. The workflow provides a reproducible path from raw sequencing reads to curated genomic outputs that can be used in downstream phylogenetic, phylodynamic, and epidemiologic analyses.

Local-first reporting

Sequencing results remain on the user's computer or analysis system. WINGS includes a local report server for navigating run-level and sample-level reports without publishing sequencing data to this site.

After generating the reports, launch the local viewer from the repository root with:

./view_reports.sh

Pandemic ESCAPE Center

WINGS was developed in support of the Pandemic ESCAPE Center and its efforts in pathogen surveillance, sequencing, bioinformatics, and understanding the emergence and spread of infectious disease threats.
