Illustration of the taxonomy tree for the Herpesviridae virus family. Virions with a known reconstructed structure (via cryogenic-electron microscopy or X-ray) are shown as 3D visualisations. Herpesviruses are enveloped with a double-stranded, non-segmented genome. They are classified into three subfamilies: Alpha, Beta and Gammaherpesvirinae. Some species infect humans and cause herpes infections, Epstein-Barr diseases or Kaposi磗 sarcoma.
