Diaspora, disease, and health care.

When groups of people relocate from their homelands to other nations, especially if the movement is involuntary, minority populations are created in the countries that receive them. The issues related to these diaspora and diasporic communities--any groups that have been dispersed outside their traditional homelands--are financial, social, historical, political, or religious. In health care, issues include heritable diseases, cultural barriers, patients' health care beliefs, and unique disease presentations. In long-term care, many residents and health care providers have relocated to the United States from other countries.
