Sex trafficking of girls and women is widespread across South Asia and is recognized as both a violent gender-based crime and major human rights violation. Inadequate empirical data exist to characterize this phenomenon and its related health consequences, such as human immunodeficiency virus (HIV) infection.

In this study, repatriated Nepalese sex-trafficked girls and women were found to have a high prevalence of HIV infection, with increased risk among those trafficked prior to age 15 years. Present findings demonstrate the need for greater attention to reducing and intervening in sex trafficking in South Asia, particularly among the very young.
