HIV-1 seroprevalence among childbearing women in northern Thailand: monitoring a rapidly evolving epidemic

Abstract

A rapid rise in HIV prevalence in childbearing women was followed by a sharp decline among young primigravidas. In each year, the prevalence was highest among young primigravidas. They may be the best subgroup of pregnant women for monitoring HIV epidemic trends, but they also represent a challenging prevention priority that will require its own targeted interventions.
