Researchers have detected a virus believed to cause Kaposi's sarcoma in the saliva of gay men. Kaposi's sarcoma is a form of cancer that usually only occurs in people with weakened immune systems, such as people with AIDS. Recently, researchers have found evidence that the cancer is caused by a type of herpes virus. In the new research, scientists detected the virus in the saliva of six of seven HIV-positive gay men with a current or previous history of Kaposi's sarcoma. NPR's Joe Neel reports.
