Since 1975, more than 3 million refugees have settled in the United States, fleeing unrest, conflict, and persecution. Refugees represent diverse ethnic, cultural, religious, socioeconomic, and educational backgrounds. Despite this heterogeneity, there are commonalities in the refugee experience. Before resettlement, all refugees must undergo an overseas medical screening to detect conditions that pose a potential health threat in the United States. On arrival, they should undergo an examination to detect diseases with high prevalence in their country of origin or departure. Refugees have higher rates of chronic pain compared with the general population, and their mental health and wellbeing are strongly influenced by their migration history. Refugees have higher rates of mood disorders, posttraumatic stress disorder, and anxiety than the general population. Some refugees have been tortured, which contributes to poorer health. Chronic noncommunicable diseases, such as diabetes mellitus and hypertension, are also prevalent among refugees. Many refugees may be missing routine immunizations and screenings for cancer and chronic diseases. Attention to reproductive health, oral health, and vision care will help identify and address previously unmet needs. Refugees face barriers to care as a result of cultural, language, and socioeconomic factors.
