PIP: While away from their families and communities, migrant workers often engage in behavior which puts them at increased risk of HIV infection. Such behavior includes drug and alcohol use, and sex with multiple partners or prostitutes. A significant proportion of northeast Thailand's rural population works away from home in either Thailand or abroad for at least part of the year. The risk behavior of this subpopulation while away from home and their subsequent behavior upon their return home has contributed to the spread of HIV in the region. In the "Letters to Loved Ones" program, women in northeast Thailand write letters to their loved ones who are working away from home to remind them of the risks of HIV/AIDS and teach them about prevention. This program and other AIDS prevention strategies grew out of the Multisectoral AIDS Prevention Strategy in Northeast Thailand. Through the program, a considerable number of women can now play important roles in sexual negotiation and health education for themselves, their families, and their communities.
