Climate change, global conflict and economic necessity are driving the highest levels of migration in history. According to the International Organization for Migration (IOM) some 192 million people are living outside their place of birth, representing about 3% of the world's population. The sheer scale of human displacement has turned migrant health into a priority global public-health issue, an issue rendered more complex by the diversity of the populations involved--from people in search of work or education to more vulnerable groups like asylum seekers and refugees. Apart from the increased potential for the spread of infectious disease that a more mobile global population brings, there is also rising concern that migrants' health needs are not always adequately met. Many countries restrict access to health care for certain migrant groups--including irregular migrants and asylum seekers. For example, until a recent court ruling, the United Kingdom restricted access to free health care to some migrants--including irregular migrants--to counter any possibility that they were entering the country primarily for free medical treatment. Dr Daniel Lopez-Acuna, director of WHO's Health Action in Crises Recovery and Transition Programmes, says migrant health issues are coming to a head in some countries, which is why they have been raised at the highest levels within the public-health agenda at national and international health levels. [ILLUSTRATION OMITTED] For Lopez-Acuna, the threat of communicable diseases spreading is only one aspect of the issue: With ever-increasing migrant populations in many countries, more strain is being put on government systems that provide health services to the public, he says. This strain is even greater when the flow of humanity is between lower-income countries, says Dr Eric Laroche, assistant director-general of the Health Action in Crises cluster of departments at the World Health Organization (WHO). Providing health care for new flows of migrants can place extra burdens on the receiving country, he says, and cites poverty, marginality and the stress of displacement among the factors affecting the health of populations on the move. At the World Health Assembly in May, WHO agreed on four strategies to address the vulnerabilities and healthcare needs of migrants. Advocacy and policy development is crucial to ensure migrants have equitable access to health services, says Lopez-Acuna. There is also a need to assess trends in migrants' health by improving country health information systems, which can help identify and fill gaps in service delivery. Lopez-Acuna also believes it is essential to train policy-makers and health stakeholders on migrant health issues, and to improve service delivery to reinforce migrant-friendly public-health services and establish minimum health-care standards for all vulnerable migrant groups. Between 1960 and 2005 the number of international migrants in the world more than doubled, from an estimated 75 million in 1960 to almost 191 million in 2005, according to a United Nations report, Trends in total migrant stock, 2005 revision. Migration is now running at about 3% annually, according to the IOM. Undocumented migration is harder to track but the International Labour Organization estimates that there are 15-30 million irregular immigrants internationally. Refugees represent 9.7% of global migrants, according to the Worm refugee survey in 2005, which estimated that there were 17 million global refugees, most of whom were hosted by African countries. Family reunification and the allure of a better life, including enhanced prospects for work or education are driving migration to countries belonging to the Organisation for Economic Co-operation and Development (OECD). From 2004 to 2005 immigration to OECD countries increased by four million people. This labour-driven trend is expected to continue as high-income countries with low fertility see their populations decline and age. …
