The region hosts around 26.6 per cent of the world’s migrants - 61.6 million people. Migrants and internally displaced persons who try to re-establish themselves in other places are often subjected to discrimination, violence and lack of access to social and health services. Migration represents a growing challenge that affects the continuity of healthcare and the management, treatment and prevention of communicable diseases. Migrants and internally displaced populations have significant impact on their communities of origin, transit and destination.
