The International Center for Research on Women (ICRW) and the Center for Social Development Studies (CSDS), Hanoi, are investigating the causes, manifestations, and consequences of HIV-related stigma and discrimination at the community level in Vietnam. This research explores the community context in which HIV-related stigma occurs and the extent to which the stigma associated with injection drug use and sex work intersects with that of people living with HIV/AIDS, and the effects of gender on these processes. In addition, the project will bring together a group of leaders from key constituencies and strengthen their capacity to serve as advocates for people living with AIDS.
