Abstract
To determine if patients initially identified by history, clinical examination, and serologic status as having asymptomatic herpes simplex virus type 2 infection report clinically recognizable genital lesions after having a detailed instructional session on the clinical signs and symptoms of genital herpes, a prospective follow-up of two groups of women, in an outpatient clinic of an urban city-county hospital, was perfromed. Two populations of women were recruited. One group was referred because they had documented asymptomatic genital herpes or were suspected of asymptomatically transmitting genital herpes to a sex partner. The other group was recruited from the hospital''s general gynecologic clinic and consisted of women with herpes simplex virus type 2 antibodies who denied a history of genital herpes. Patients had a one-on-one interview describing the clinical symptoms of genital herpes. Twelve of nineteen women with herpes similex virus type 2 antibodies who had documented asymptomatic genital herpes or were suspected of asymptomatically transmitting infection to a sex partner, and 18 of 43 women with herpes simplex virus type 2 antibodies who were recruited from the gynecologic clinic developed clinically recognizable genital lesions during a 5-month follow-up. Symptomatic genital herpes was the most frequent gynecologic complaint identified during follow-up. Approximately 50% of women with herpes simplex virus type 2 antibodies who do not initially report a history of genital lesions do indeed have clinically symptomatic genital herpes. These women can be accurately counseled and taught to distinguish genital herpes from other genitourinary infections. Identification of symptomatic recurrences and counseling to avoid sexual activity during these episodes may help reduce transmission of genital herpes.
