Every year, nearly 250 million people move across borders temporarily or permanently for a job opportunity, studying, to flee a crisis back home, or for other reasons. Another 750 million move for similar reasons within the borders of their countries. With the understanding that human mobility affects public health, and health affects human mobility and migrants, for decades, IOM has been providing critical health services to women, children and men on the move, while standing by governments for technical and operational support as needed. In 2019, in lower-income settings and in complex emergencies, along the world’s most perilous migration routes, in the aftermath of natural disasters or in response to disease outbreaks, IOM’s health teams have provided hundreds of thousands with primary health-care consultations, mental health and psychosocial support, sexual and reproductive health care, pre-migration health services, and much more. This year, more than ever before, as the world reels from the socioeconomic impact of COVID-19, we have experienced that health is a cross-cutting component of overall human development and well-being.
