Establishment of a Universal Viral Classification System by the ICTV

In 1966, the International Committee on Taxonomy of Viruses (ICTV) established a universal classification system for viruses, utilizing ranked taxons to categorize them effectively. The hierarchical structure includes Order (-virales) as the highest recognized taxon, followed by Family (-viridae), Subfamily (-virinae), Genus (-virus), and Species (e.g., tobacco mosaic virus). This classification system allows for systematic comparisons of various viruses, including those affecting vertebrates and plants, facilitating research and understanding of viral diseases across different hosts.

    8. Meeting Classification Needs A universal system of viral classification and a unified taxonomy was established by the International Committee on Taxonomy of Viruses (ICTV) in 1966. The system makes use of a series of ranked taxons, with the: - Order (-virales) being the highest currently recognized. - then Family (-viridae) - Subfamily (-virinae) - Genus (-virus) - Species ( eg: tobacco mosaic virus)
