Genital disease caused by HSV-1 and HSV-2 have different clinical presentation and prognostic features. The objective of this study was to estimate the proportion of cases of genital herpes caused by HSV-1 and identify the main clinical and epidemiological characteristics in a busy, public STD clinic.


We performed a retrospective chart review of individuals with culture and/ or type-specific HSV serology collected during the year of 2007 at the Downtown STD clinic of the Miami-Dade County Health Department. Demographics and clinical information were included in the analysis. Primary genital herpes caused by HSV-1 was defined by a positive culture for HSV-1 and a negative serological test. Recurrent genital HSV-1 was defined by a positive culture and a positive serological test for HSV-1.


A total of 663 individuals were tested for HSV infection in the study period. 418 (63%) were males and 245 (37%) females. In this sample, the prevalence for HSV-1 was 42.1% and HSV-2 was 36.7%. Cultures were obtained in 325 individuals and were positive in 94 cases. Most of the cultures were positive for HSV-2 (84%) nonetheless 16% were positive for HSV-1. All HSV-2 positive cultures were from the anogenital areas. Out of the 15 individuals with a HSV-1 positive culture, eleven were from genital ulcers and 4 from the oral mucosa. Among those eleven individuals with positive genital HSV-1 cultures 5 were women and 6 men, the majority were heterosexuals (9/11) and they were all HIV-negative. Less than half of them (5/11) complained of symptoms related to the ulcers, but all of them had ulcers during the examination. Nine of them did not have HSV- specific serology performed, one had a negative test and one had a positive test.


HSV-1 is not an uncommon cause of genital herpes in patients presenting with genital ulcers in this STD clinic.
