Introduction: Herpes Simplex virus type 2 (HSV-2) infection is associated with an increased risk of human immunodeficiency virus type 1 (HIV-1) acquisition and transmission. Individuals co-infected with HIV-1 and HSV-2 may have longer lasting, more frequent and severe outbreaks of herpes symptoms. Previous studies have assessed HSV-2 seroprevalence and associated risk factors in adult populations. However, there is limited data on the HSV-2 seroprevalence among adolescents and youth living with HIV-1. The study aimed to determine the HSV-2 seroprevalence and associated risk factors among adolescents and youth living with HIV-1 at referral hospital setting in Northern Tanzania.

Methodology: A cross-sectional survey was conducted between February and July 2017 among HIV-1-infected individuals aged 10-24 years attending the Child -Centred Family Care Clinic at Kilimanjaro Christian Medical Centre. Blood specimens from 180 individuals were collected for ELISA-based detection of HSV-2 antibodies. Associations between risk factors and HSV-2 seroprevalence were analysed by univariate and multivariate logistic regression models.

Results: The overall HSV-2 seroprevalence was 18% (32/180). A significant HSV-2 seroprevalence was noted among adolescents and youth, who reported having had sexual intercourse than those who never had sexual intercourse (28.9% vs 13.3%, p = 0.02). Youths aged 20-24 had six folds higher risk of HSV-2 seroprevalence compared to those aged 10-14 years (AOR = 5.97 95% CI 1.31 – 27.19, p = 0.02).

Conclusions: Our study found that HSV-2 seroprevalence increased by age among adolescents and youth living with HIV-1. Age-specific approaches might play an important role in interventions targeting HSV-2 infection.
