RESUMO
To obtain a better understanding of the evolving HIV-1 epidemic in Thailand, we utilized antibody to hepatitis C virus (HCV) to indicate the mode of HIV-1 transmission. Although the proportion of men with HCV co-infection increased between 1995 and 2000, the prevalence was similar, whereas the prevalence of men not co- infected decreased (1.93-0.46%). This suggests that HIV-1 infection associated with parenteral transmission has been stable despite a dramatic reduction in the sexual transmission of HIV-1.

This study examined changes in sexual behavior among Thai army conscripts from 1992 to 1998 in association with human immunodeficiency virus (HIV) seroprevalence. The sexual behavior survey was started in 1992 during the epidemic of HIV infection in Thailand, when sexual transmission was the most common route and young men were at high risk, and it has continued yearly since 1995. The self-reported questionnaires were administered to randomly selected conscripts (N = 294 in 1992, N > 4,000 in 1995-1998), and trends in sexual behaviors were studied. The results showed that risky sexual behaviors generally decreased in relation to the decline in HIV seroprevalence, but the conscripts still engage in risky sexual behaviors. Appropriate interventions should be implemented to change these behaviors. The periodic sexual behavior surveys will be useful in evaluating program outcomes and planning for future interventions.

To assess whether patterns of HIV transmission have changed in Thailand, we tested for antibody to hepatitis C virus (HCV) as a marker for parenterally acquired infection among HIV-infected and uninfected young Thai men. Antibody to HCV was present in 49.5% of HIV-infected men and 2.2% among uninfected men. These data suggest that a significant number of HIV infections among young men in Thailand may be associated with injection drug use.

Characterization of the HIV epidemic in Thailand has benefited from the systematic testing of young men upon entry into the military. These data, which have shown that public health measures can reverse an HIV epidemic, have been reanalyzed with current geographic information systems methods. The resulting maps are, thus far, the best means of visualizing the geography of the dynamic HIV epidemic in Thailand.
