In what is being hailed as a landmark breakthrough in HIV prevention, a new study shows that giving anti-AIDS drugs to HIV-positive people can reduce the transmission of the virus to spouses and partners by 96 percent, U.S. researchers said Thursday. Though studies had suggested that treatment of patients with antiretroviral drugs could slow transmission of the virus, the new results represent the first large clinical trial to confirm those suggestions and showed that the drugs are unexpectedly effective. The results of the study of nearly 1,800 couples in the United States and southern Africa were so dramatic that the National Institutes of Health terminated it four years before its scheduled completion to get the word out.
