Human mobility is one of the most defining characteristics of our global history, yet for millions, the act of moving across borders is fraught with systemic hurdles. Today, the scale of migration has reached unprecedented levels, with more than a billion people—approximately one in eight individuals globally—on the move according to the World Health Organization (WHO). As these populations navigate new environments, the urgency for inclusive health policies for refugees and migrants has shifted from a humanitarian ideal to a critical public health necessity.
For those of us in the medical community, the data is clear: the experience of migration is a primary determinant of health. Whether driven by conflict, poverty, environmental degradation, or a search for education, the journey and the destination both shape a person’s physical and mental well-being. But, the path to universal health coverage remains obstructed by institutional discrimination, restrictive policies, and deep-seated cultural barriers that often leave the most vulnerable without a safety net.
Recent efforts by the WHO to establish a global baseline for migrant-inclusive health highlight a complex landscape. While there is encouraging progress in how nations integrate these populations into national strategies, significant gaps persist in data collection and governance. Achieving a truly migrant-responsive health system requires more than just opening clinic doors; it requires a fundamental shift in how we view the right to health for all, regardless of legal status or origin.
The Scale of Global Displacement and Migration
The numbers reflecting human mobility are staggering and continue to rise. As of 2024, an estimated 304 million people are international migrants, a figure that has more than doubled since 1990 when the count stood at 154 million per WHO data. This diverse group includes approximately 170 million migrant workers and 7 million international students, illustrating that migration is driven by a wide array of professional and personal aspirations.
Parallel to voluntary migration is the crisis of forced displacement. We see estimated that 117.3 million people are forcibly displaced globally according to WHO reports. This total includes 73.5 million internally displaced persons (IDPs), 36.4 million refugees, and 8.4 million asylum seekers. The human toll is particularly acute among the youth, with 49 million children among the displaced, including 2.3 million who were born into refugee life.
These populations often arrive in host countries already burdened by the trauma of war, economic collapse, or disasters. The conditions of their journeys—characterized by inadequate access to clean water, food, and sanitation—increase their susceptibility to a range of health crises. These include communicable diseases, accidental injuries, hypothermia, and delivery-related complications for pregnant women as detailed by the WHO.
Barriers to Care and Health Inequities
Despite the inherent human right to health, refugees and migrants frequently experience poorer health outcomes compared to host populations. These inequities are rarely the result of a single factor but are instead the product of intersecting vulnerabilities. Language and cultural barriers often make the first point of contact with a healthcare provider a source of frustration rather than relief, while institutional discrimination can lead to suboptimal care or the outright denial of services.
Restrictive policies in transit and destination countries further exacerbate these risks. When legal status is precarious, the fear of detention or deportation often outweighs the urgency of medical need, leading individuals to avoid seeking care until a condition becomes critical. This not only harms the individual but creates systemic risks for the broader public health infrastructure by leaving communicable diseases untreated and preventable chronic conditions unmanaged.
The COVID-19 pandemic served as a stark reminder of these vulnerabilities. Refugees and migrants faced increased risks of infection and death, while the accompanying lockdowns and travel restrictions intensified their economic instability and highlighted the existing gaps in health service utilization according to WHO analysis.
Progress Toward Migrant-Responsive Health Systems
In response to these challenges, the WHO established the Health and Migration Programme (PHM) in 2020 to provide global leadership and align efforts with the Global action plan: promoting the health of refugees and migrants 2019–23 as reported by the WHO. A key milestone in this effort is the “World report on promoting the health of refugees and migrants: Monitoring progress on the WHO global action plan,” which utilizes data from 93 Member States to track how countries are meeting their commitments to inclusive health.
The report indicates that countries are increasingly incorporating refugee and migrant health into their national policies and public health priorities. There is a growing recognition that inclusive health systems are not merely a matter of charity but a strategic investment. When refugees and migrants have access to care, they are better positioned to contribute to their host communities through labor markets, caregiving, and social cohesion. The economic contributions of migrants, such as remittances, can improve health service access in their countries of origin per WHO findings.
The shift toward evidence-based policy is encouraging. By relying on science and established norms, governments can design systems that address the specific physical and mental health needs of displaced populations—needs that are heavily influenced by the conditions of their origin, the perils of their journey, and the environment of their destination.
Identifying the Persistent Gaps
While the trajectory is positive, the path to universal health coverage for migrants remains uneven. The WHO’s global snapshot reveals that several critical gaps continue to hinder progress. One of the most significant is the lack of robust data systems. Without the routine collection and analysis of migration-related health data, policymakers are essentially operating in the dark, unable to accurately allocate resources or identify emerging health trends within these populations according to the Health and Migration Programme.
Governance and participation also remain major hurdles. In most countries, refugees and migrants are under-represented in the decision-making processes that govern the very services they rely on. True inclusivity requires the meaningful participation of these individuals in the design and delivery of primary health care.
the level of access varies wildly depending on the subgroup. While refugees may have more structured access to certain services, other groups—including migrant workers, international students, and those in irregular legal situations—often find themselves inconsistently covered or entirely excluded from national health frameworks per WHO reports.
Key Challenges in Inclusive Health Implementation
| Barrier Category | Primary Impact | Systemic Result |
|---|---|---|
| Institutional | Restrictive policies and legal precariousness | Avoidance of care due to fear of deportation |
| Cultural | Language gaps and lack of sensitive care | Misdiagnosis and poor patient adherence |
| Structural | Gaps in national health data systems | Inefficient resource allocation and planning |
| Social | Xenophobia and discrimination | Psychological distress and social isolation |
The Path Forward: Strengthening Global Health Security
To move from policy to practice, the international community must prioritize the integration of refugees and migrants into all levels of national health strategies. This includes not only health services but also a coordinated approach across housing, education, and employment, acknowledging that health is inextricably linked to these social determinants.
Training for healthcare providers is another essential pillar. Moving toward “culturally responsive care” means equipping doctors, nurses, and administrators with the tools to navigate linguistic barriers and understand the unique traumas associated with forced displacement. When care is delivered with dignity and cultural competence, patient outcomes improve, and trust in the health system is restored.
the health of refugees and migrants is an integral part of global health security. In an interconnected world, a health crisis in one marginalized community can quickly become a broader public health threat. By ensuring that everyone—regardless of where they were born or how they arrived—has access to essential health services, we strengthen the resilience of health systems for the entire population.
The continued collaboration between the WHO, the International Organization for Migration (IOM), and the UN High Commissioner for Refugees (UNHCR) will be vital in translating global commitments into local actions. The goal is clear: a world where the right to health is a reality for all, and where migration is no longer a barrier to receiving life-saving care.
The WHO continues to monitor progress through its Global Action Plan, with ongoing updates expected as Member States report on the integration of migrant-inclusive policies into their national frameworks.
