Virus Taxonomy

Taxonomy lies at the uneasy interface between biology and logic. The processing of information follows somewhat different rules in these two systems and the role of taxonomy is to reconcile them as tidily as possible. To this end, the Virology Division of the International Union of Microbiological Societies (IUMS) charged the International Committee on Taxonomy of Viruses (ICTV) with the task of developing, refining, and maintaining a universal virus taxonomy. The goal of this undertaking is to categorize the multitude of known viruses into a single classification scheme that reflects their evolutionary relationships, i.e. their individual phylogenies.

The ICTV Online (10th) Report is is the standard and definitive reference for virus taxonomy. It is a freely available, online resource, that updates and replaces previous ICTV Reports that had been available as printed books. The Report can be accessed from the "ICTV Reports" menu selection above, or from the following link: http://ictv.global/report/
