Virus Taxonomy

The ICTV Report on Virus Classification and Taxon Nomenclature

The ICTV Report is a freely available, online resource, that updates and replaces previous ICTV Reports that had been available as printed books. The starting point for the current Report (also previously referred to as the Online, 10th Report) is the ICTV 9th Report, published in 2011. ICTV Study Groups, consisting of leading experts in the field, are updating the information from the chapters of the 9th Report to produce current Report chapters. In addition, chapters for new viral taxa created since the 9th Report are also being produced. Chapters will be updated on a regular basis to describe recent taxonomic changes resulting from the approval and ratification of new taxonomic proposals. 

Summaries of the Online Report chapters are published in the Journal of General Virology in the new section, ICTV Virus Taxonomy Profiles. These profiles provide concise review-type articles of individual chapters from the online Report. Written by ICTV Study Groups, these reviews provide overviews of the classification, structure and properties of individual virus orders, families and genera. These summaries are linked to the full Online Report chapters on this website and are indexed in PubMed. An Editorial has been written by ICTV President, from Dr Andrew Davison.

The Online Report and ICTV Virus Taxonomy Profiles have been made possible thanks to a Biomedical Resources grant from Wellcome.

The 9th ICTV Report on Virus Taxonomy

In addition to the current ICTV Report, we are now providing access to an online version of the 9th ICTV Report (see link above). Published in 2011, this was the last printed Report of the ICTV and presents detailed descriptions of virus taxa from the 2009 release of the ICTV taxonomy. If there is an updated version available for any chapter from the 9th Report, there will be a link at the top of the chapter that will take you to the 10th Report chapter.
