A previous study on patterns of migration of HIV-infected persons suggested that most patients in a rural setting in eastern Tennessee acquired their disease in an urban area, typically during a period of prolonged residence. Disease and disability were the most common reasons for returning to their hometown. We studied our urban, border-city HIV clinic population to see whether similar patterns of migration were discernible. Fifty-one of the 103 patients studied lived outside the El Paso/Juarez area when they contracted HIV infection. The major reason cited for returning home was a desire to return to family (25%). Those who returned and those who had never left showed no statistically significant difference in age, race, or risk factors. This study suggests that migration of HIV-infected patients back to their hometown does not appear to be an exclusively rural phenomenon.
