This document aims to provide practical, non-clinical guidance to help concerned health providers understand the phenomenon of human trafficking. It outlines the health provider's role in providing care and describes some of the limitations of his or her responsibility to assist. The development of this handbook was supported by the UN.GIFT and coordinated by the International Organization for Migration and the Gender Violence & Health Centre of the London School for Hygiene & Tropical Medicine.More information about human trafficking on the website of IOM.
