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.
