Few countries have shown the link between behavior and HIV infection as clearly as Thailand. Overall, behavioral changes have reduced the number of new HIV infections each year from almost 143,000 in 1991 to 29,000 in 2000. With support from the Thai government and leaders from all levels of society, emphasis was placed on reducing the risky sexual practices and the vulnerability of young people as well as on more specific risky behaviors of particular groups. Efforts were made to increase knowledge and awareness of HIV, as well as to improve life skills, such as decision-making and negotiation. Condoms were promoted and educational opportunities for young girls were increased so that they were less likely to become sex workers. Also, national policy guidelines to protect the human rights of people living with HIV/AIDS were issued. As shown in the graph, one of the most striking effects of the national program was a reduction in visits to sex workers, the behavior most closely associated with HIV infection in Thai studies.
