This report on migrant and seasonal farm workers (MSFWs) uses data from focus groups, a survey, and interviews of MSFWs and service providers conducted in New York state plus the references to describe the risk and inadequate access to testing and care that MSFWs face. It emphasizes issues relating to HIV/AIDS, barriers to accessing health care and related services, and common elements of successful MSFW programs. The data indicate that HIV/AIDS is escalating among MSFWs, and that immediate steps need to be taken to prevent devastating impact among the population and their families. Recommendations are provided for improving health outcomes among MSFWs, preventing HIV transmission, and providing continuous comprehensive care and support for HIV-infected MSFWs. Appendices A and B list New York State Department of Health and AIDS Institute contracts providing health care for MSFWS.
