PoxviridaeSubfamily Chordopoxvirinae Orthopoxvirus Parapoxvirus Avipoxvirus Capripoxvirus Leporipoxvirus Suipoxvirus Molluscipoxvirus Yatapoxvirus Subfamily Entomopoxvirinae Entomopoxvirus A Entomopoxvirus B Entomopoxvirus C Poxviruses (members of the family Poxviridae) can infect as a family both vertebrate and invertebrate animals. Poxviridae viral particles (virions) are enveloped and vary in their shape depending upon the species but are generally shaped like a brick or as an oval form similar to a rounded brick. The virion size is around 200 nm in diameter and 300 nm in length and carries its genome in a single, linear, double-stranded segment of DNA . By comparison, Rhinovirus is 1/10th as large as a typical Poxviridae virion. Electron micrographs of Orthopoxvirus and Parapoxvirus Genera, including the smallpox virus, have been collected by the International Committee on Taxonomy of Viruses in their Poxviridae picture gallery. The name of the family, Poxviridae, is a legacy of the original grouping of viruses associated with diseases that produced pocks in the skin. Modern viral classification is based on the shape and molecular features of viruses, and the smallpox virus remains as the most notable member of the family. The following genera are currently included here:
