Abstract
BACKGROUND: Considering the high prevalence and clinical importance of herpes simplex virus (HSV) infection worldwide, we aimed to evaluate the seroprevalence of HSV-1 and HSV-2 in a population aged between 15 and 35 years in Mashhad, Iran. METHODS: This cross-sectional study was conducted on 916 cases composed of 288 (31.4%) men and 628 (68.6%) women. Using ELISA method, the presence of IgM and IgG antibodies against HSV-1 and HSV-2 was assessed. RESULTS: Among the population studied, 681 (74.3%) cases were positive for anti-HSV antibodies, while 235 (25.7%) cases were negative. Moreover, no IgMs were found and all positive subjects had IgG antibodies. Age (p < 0.001), occupation (p < 0.001), education (p = 0.006), smoking (p = 0.029), and BMI (p = 0.004) demonstrated a significant association with HSV-1 and HSV-2 infection. CONCLUSION: Our study indicates a high seroprevalence of HSV infection; however, there was no cases positive for IgM antibodies, suggesting the high prevalence of latent infection.
