The rights of nations to protect against infectious disease and unsafe medical practices, as well as the rights of human beings displaced by war, traffi cking, and economic and cultural disruption, are critical concerns for health policy makers. Poverty and social disparities are key factors in the growth of global migration. Therefore, it is timely to consider whether mobility is a human right, and whether those who migrate have rights to health care in their new country. These questions should be considered by health policy makers within the ethical contexts of individual autonomy, social justice, nonmalefi cence, and benefi cence.
