Virus Taxonomy

Orthography: ("spelling conventions")
  • The names of virus orders, families, subfamilies, genera and species should be written in italics with the first letter capitalized.
  • Other words are not capitalized unless they are proper nouns, e.g. Tobacco mosaic virus, Poliovirus, Murray River encephalitis virus.
  • This format should only be used when official taxonomic entities are referred to - it is not possible to centrifuge the species Poliovirus for example, but it is possible to centrifuge poliovirus.
  • Italics and capitalization are not used for vernacular forms (e.g. rhinoviruses, c.f. the genus Rhinovirus), for acronyms (e.g. HIV-1), nor for adjectival usage (e.g. poliovirus polymerase).
  • See: M.H.V. Van Regenmortel: How to write the names of virus species. Arch.Virol. 144 (1999) 5, 1041-1042.

    In 2010 the International Committee on Taxonomy of Viruses (ICTV) formally recognized:

    • 6 Orders
    • 87 Families
    • 19 Subfamilies
    • 348 Genera
    • and 2285 Species of viruses

    This formal taxonomy is constantly changing, so readers are advised to click on the above link where they will be able to find the latest information for themselves. However, as a convenience, the structure of the major taxonomic groups of viruses as recognized at the time of publication is given below:
