Tuberculosis control in migrant populations : guiding principles and proposed actions

Overview

Human migration, defined as the “movement of a person or a group of persons, either across an international border, or within a State”, has been increasing over the last several decades. According to current United Nations estimates, there are approximately 232 million international migrants worldwide, with over 71 million living in Asia, and an additional 740 million internal migrants moving within their own countries. The total number of migrants worldwide is greater than the population of all but the world’s two most-populous nations.
