See text Varicellovirus (var′i-sel′ō-vi′rŭs) is a genus of viruses belonging to subfamily Alphaherpesvirinae, a member of family Herpesviridae.

[2][1] The following 20 species are assigned to the genus in ICTV 2022[1] As with other alphaherpesviruses, the virus particle has a layered structure: Virions consist of an envelope, a tegument, a nucleocapsid, and a core.

Tegument is disordered; they do not display a structure and proteins in variable amounts are arranged sometimes in an asymmetric layer located between envelope and capsid.

[2] The capsid consists of 162 capsomer proteins with a hexagonal base and a hole running halfway down the long axis.

[2] Only one member of the Varicellovirus genus, Varicella zoster virus (HHV-3) infects Homo sapiens (humans).
