Refugee health is an interdisciplinary academic field and research concept that investigates the health status, determinants, and healthcare access of populations displaced across international borders due to conflict, persecution, or other significant disruptions. This field specifically examines the complex interplay of pre-migration trauma, transit experiences, and post-resettlement factors influencing the physical, mental, and social well-being of refugees, often focusing on vulnerabilities, resilience, and health disparities. Its significance lies in generating evidence to inform public health interventions, policy development, and equitable healthcare provision for these populations globally.
