# Virus-Host Database for Viral Genomics

## Dataset Summary

This dataset consolidates information from the [Virus-Host DB](https://www.genome.jp/virushostdb/), a resource by the Kyoto University Bioinformatics Center that documents virus-host relationships using taxonomy identifiers from NCBI and RefSeq. It includes viral genomic data, host associations, and metadata, offering a comprehensive resource for studying virus-host interactions.

## Source and Citation

Data in this dataset is sourced from the Virus-Host DB, maintained by Kyoto University’s Bioinformatics Center, which compiles data from GenBank, UniProt, and additional literature curation. Please cite:
- **Mihara, T., et al.** (2016). *Linking Virus Genomes with Host Taxonomy*. _Nucleic Acids Research_, 44(D1): D549-554. DOI: [10.1093/nar/gkv1261](https://doi.org/10.1093/nar/gkv1261).

## Dataset Structure

### Key Fields
- **virus_tax_id**: NCBI Taxonomy ID for the virus
- **host_tax_id**: NCBI Taxonomy ID for the host
- **sequence**: Viral genome sequence
- **lineages**: Taxonomic classifications for viruses and hosts
- **disease**: Associated diseases
- **pmid**: PubMed ID references

### Usage Example
Load the dataset using the Hugging Face library:
```python
from datasets import load_dataset
dataset = load_dataset("zwang2/virus_host_db")
```

## Applications

This dataset supports research in virology, epidemiology, and bioinformatics, enabling analysis of virus evolution, host specificity, and pathogen emergence patterns.
