title: Expanded AIDS case definition increases Pennsylvania's reported AIDS cases.
abstract: At the beginning of 1993, the Centers for Disease Control and Prevention adopted an expanded case definition of AIDS and a revision of the classification system for HIV infection for persons ages 13 years or older. This article explains the changes and their effects, defines the new system categories, and offers resources for physicians treating HIV-infected patients.
