Infectious disease screening for refugees resettled in the United States.

Refugees resettling in the United States carry a significant burden of infectious diseases as a result of exposures in their countries of origin and the circumstances of their migration. Overseas screening is required before entry, but it incompletely assesses infectious diseases in refugees. Domestic health assessment has the potential to provide more comprehensive assessment for infectious diseases. Screening protocols ideally should test for tuberculosis, hepatitis B, and intestinal and other parasites and should include mechanisms for providing or updating immunizations. Testing for other infectious diseases, including malaria, hepatitis C, human immunodeficiency virus, and sexually transmitted diseases, can be performed on the basis of clinical signs and symptoms. This article reviews the current status of overseas and domestic health screening for refugees, infectious disease burdens, and future goals for health assessment of refugees and other immigrants.
