The Herpesviridae are a large family of DNA viruses that cause diseases in animals, including humans. The Herpesviridae family is divided into 3 subfamilies. The Alphaherpesvirinae, Betaherpesvirinae and Gammaherpesvirinae. The Herpes Simplex Virus 1 (HSV-1), Herpes Simplex Virus 2 (HSV-2) and Varicella Zoster Virus (VZV) belongs to Alphaherpesvirinae subfamily, which is distinguished by reproducing more quickly than other subfamilies of Herpesviridae.
Infection with the Herpes Simplex Virus is categorized based on the site of infection, with oral herpes being the most common and genital herpes the second most common. HSV-1 is the main cause of oral herpes and HSV-2 the main cause of genital herpes. Varicella Zoster Virus is the cause of chicken-pox and shingles.
