ICTV Study Group Information

The ICTV maintains a Study Group for each virus family. Study Groups examine the classification and nomenclature of the viruses that are members or potential members of the family, and develop criteria (phenotypic and genotypic characters) that determine which viruses belong to a particular taxon. They also review proposals to create new taxonomy or modify existing taxonomy.

The content available from the links to the left, provide information on the indicated virus family or genus. This content is maintained by the relevant Study Groups.
