RESUMO
OBJECTIVE: To study the factors associated with the presence of antibodies against herpes simplex virus type 1 (HSV-1) and to screen for HSV-1 in genital samples. MATERIALS AND METHODS: Students answered a survey and provided biological samples (blood and genital discharge). The detection of IgG and IgM antibodies against HSV-1 was performed by an ELISA test. From IgM positive samples we sought and extracted genital DNA and identified a beta-globulin gene and HSV-1. RESULTS: Eight hundred and fifteen students participated. IgG/HSV-1 seroprevalence was 56.7%, HSV-1 infection was associated with number of sexual partners, exchanging sex for money, same sex relationships and occasional partners. IgM/HSV-1 seroprevalence was 18.2%, 91 samples were positive for human beta-globuline but none for HSV-1 DNA. CONCLUSIONS: Epidemiological evidence suggests that HSV-1 could be transmitted by sexual contact among college students; however, HSV-1 was not detected in any of the genital samples analyzed. To further test our hypothesis we need to study HSV-1 among high risk groups or increase our sample size.

Objetivo: Estudiar los factores asociados a la presencia de anticuerpos contra el virus del herpes simplex tipo 1 (HSV-1), así como identificar éste en muestras genitales. Métodos: Los estudiantes universitarios contestaron un cuestionario y proporcionaron muestras biológicas (sangre y exudado genital). La detección de anticuerpos clase IgG e IgM contra HSV-1 se realizó mediante ELISA. A partir de las muestras positivas a IgM se buscó su muestra genital, se extrajo ADN y se identificaron betaglobina humana así como HSV-1. Resultados: Participaron 815 estudiantes, la seroprevalencia de IgG-HSV-1 fue de 56.7 %; la infección se asoció con el número de parejas sexuales, intercambiar sexo por dinero, relaciones con personas del mismo sexo y parejas ocasionales. La seroprevalencia de IgM-HSV-1 fue de 18.2 %; a partir de estas muestras se buscó infección genital por HSV-1; 91 muestras fueron positivas a betaglobina pero en ninguna se detectó HSV-1. Conclusiones: Los datos epidemiológicos sugieren que el HSV-1 puede ser una infección de transmisión sexual en la población universitaria analizada, sin embargo, en ninguno de los individuos se corroboró presencia genital del HSV-1. Es necesario estudiar esta infección en otras poblaciones susceptibles o incrementar el tamaño de la muestra.
