Even as the AIDS epidemic enters its second decade, Americans still misunderstand how the disease is transmitted and stigmatize those with AIDS, says UC Davis psychology researcher Gregory Herek in an article published this month in the American Journal of Public Health. Large percentages of those surveyed believed they could contract AIDS through casual contact. About half erroneously believed they could contract AIDS from someone with HIV through a shared drinking glass, a cough or sneeze, or an insect bite. A disturbingly high number of people supported quarantine of those with AIDS or expressed negative feelings toward them, Herek said. Nearly 50 percent also said they would avoid shopping at a neighborhood grocery store if the owner had AIDS. From the survey results, Herek concludes that reducing stigma and fostering compassion toward people with AIDS should be part of AIDS education and prevention programs.
