Migration and AIDS in Mexico: an overview based on recent evidence.

OBJECTIVES: Provide an overview of the relation between migration to the United States and AIDS cases in Mexico. Characterize the sexual behaviors of Mexican migrants. Describe HIV/AIDS prevention and clinical attention actions developed.
METHODS: The following were analyzed: AIDS cases databases, various prevalence studies, the migrants survey, and information of the Ministries of the Interior and of Health. A documental analysis was undertaken of works published between 1992 and 2000 on migration and AIDS.
RESULTS: In terms of their sexual practices, migrants in the past year had more sexual partners, tended to use a condom in their most recent relation in greater proportion, and had greater use of injected medicines and drugs. Two bi-national programs undertake epidemiological surveillance activities, while several initiatives have used innovative formats to provide prevention information to migrants. Imminent universal coverage leaves the challenge to assure quality of attention for migrants.
CONCLUSIONS: Studies to evaluate the impact of international migration on distribution of infected persons will be indispensable to establish priorities in prevention and attention among migrants. More information is needed on bi-national health projects to understand the impact they may have in prevention, while continuity of the prevention initiatives must be guaranteed. Attention to migrants in bi-national contexts requires information exchange agreements on migrants living with the HIV/AIDS.
