GNUVID

GNUVID assigns allele-based sequence types to SARS-CoV-2 whole-genome sequences for rapid genomic surveillance and tracking of clonal complexes.

Key Features:

• Rapid whole-genome sequence typing: Employs an allele-based scheme to assign sequence types to SARS-CoV-2 genomes quickly.
• Adaptability with growing databases: Updates to allele definitions accommodate new genomic variants as sequence databases expand.
• Phylogenetic consistency: Sequence typing aligns with phylogenetic analyses to reflect evolutionary relationships among isolates.
• Geographical tracking of clonal complexes: Identifies clonal complexes and their geographic distributions to monitor spread and transmission.
• Detection of emergent strains: Flags novel allele combinations indicative of potentially increased transmissibility or virulence.

Scientific Applications:

• Epidemiology: Traces transmission patterns of SARS-CoV-2 by comparing sequence types across regions.
• Public health surveillance: Provides rapid genotype assignments to support monitoring of emerging viral strains.
• Viral evolution research: Supports studies of SARS-CoV-2 evolutionary dynamics through allele-based typing consistent with phylogeny.

Methodology:

Processes SARS-CoV-2 whole-genome sequences using an allele-based typing scheme that compares allele variations to assign sequence types and identify clonal groups and their geographic distribution.
