Risk of developing active tuberculosis following tuberculosis screening and preventive therapy for Tibetan refugee children and adolescents in India: An impact assessment.

Background: Tuberculosis (TB) rates among Tibetan refugee children and adolescents attending boarding schools in India are extremely high.
