The taxonomy of herpesviruses has been updated by the International Committee on Taxonomy of Viruses (ICTV). The former family *Herpesviridae* has been split into three new families: *Herpesviridae*, *Alloherpesviridae*, and *Malacoherpesviridae*. The revised *Herpesviridae* retains mammal, bird, and reptile viruses, while *Alloherpesviridae* includes fish and frog viruses, and *Malacoherpesviridae* contains a bivalve virus. Three new genera have been created within *Herpesviridae*: *Proboscivirus*, *Macavirus*, and *Percavirus*. These genera are formed by the transfer of species from established genera and the addition of new species. The names of some nonhuman primate virus species have also been changed. The family *Alloherpesviridae* includes the genus *Ictalurivirus* and the new species *Cyprinid herpesvirus 3*. The family *Malacoherpesviridae* incorporates the new genus *Ostreavirus* with the species *Ostreid herpesvirus 1*. The classification update reflects the genetic distances among the three groupings of herpesviruses and aims to balance logic and utility in taxonomy.The taxonomy of herpesviruses has been updated by the International Committee on Taxonomy of Viruses (ICTV).
