      Like a growing number of young women in Vietnam's northern part city of Haiphong, Pham Thi Hue

was infected with HIV by her husband, one of the town's many drug users. But instead of being shamed

into silence, as Vietnamese with HIV and AIDS are, the 25-year-old tailor and mother of one child went

public, appearing on television and at conferences. Her business suffered and her neighbors insulted (辱骂)

her, but Hue has now become the public face of Mothers and Wives, an HIV/AIDS support group established

in Haiphong by a Norwegian nongovernmental organization and her neighborhood's People's Committee. Last

year, she founded a smaller group named after a local flower. People who need advice on treatment or help

can dial a hot line and get assistance from able and empathetic (同情的) HIV victims. "We gather to support

each other," Hue says. "When we are sick, what we need most is encouragement and comfort from people

who understand our situation and are willing to share our happiness, as well as our sadness."

      On a hot and damp night last month, Hue welcomed into her small home a very thin woman, also a tailor,

who was HIV positive. The woman tearfully told Hue that she had not told anyone about her condition, fearing

that she would lose customers and that her daughter would be insulted at school. Hue became the wise elder,

offering medical and personal advice.
