Abstract In 1994 Chang and Moore reported on the latest of the gammaherpesviruses to infect humans human herpesvirus 8 HHV-8 1 . This novel herpesvirus has and continues to present challenges to define its scope of involvement in human disease. In this review aspects of HHV-8 infection are discussed such as the human immune response viral pathogenesis and transmission viral disease entities and the virus s epidemiology with an emphasis on HHV-8 diagnostics. 1. The Herpesviruses . Classification of herpesviruses More than 100 herpesviruses have been discovered of which all are double-stranded DNA viruses that can establish latent infections in their respective vertebrate hosts however only eight regularly infect humans. The Herpes-virinea family is subdivided into three subfamilies the Alpha- Beta- or Gammaherpesvirinea. This classification was created by the Herpesvirus Study Group of the International Committee on Taxonomy of Viruses using biological properties and it does not rely upon DNA sequence homology. However researchers have been able to identify and appropriately characterize the viral subfamilies using DNA sequence analysis of the
