Definition
Genital herpes is a sexually transmitted viral infection characterized by primary and recurrent genital inflammation and lesions.

Pathophysiology
Genital herpes is mostly caused by HSV-2 and HSV-1 transmitted through sexual contact.

Epidemiology
The incidence of genital herpes in North America is estimated to range from 5,000 to 24,000 per 100,000 people per year.

Disease course
Clinical manifestations include lesions of mucous membrane presenting as bilateral clusters of macules, papules, followed by vesicles, pustules, and ulcers on the external genitalia with symptoms of pain, itching, burning, dysuria, lymphadenopathy, fever, cervicitis (women), and proctitis (homosexual men). Complications in women include aseptic meningitis and urinary retention. Recurrent episodes may show prodromal symptoms of paresthesia and pains in the area of lumbosacral dermatomes. Asymptomatic genital shedding without any clinical symptoms is quite frequent. The disease increases psychological stress with frequent recurrences.
