title: Notification of syringe-sharing and sex partners of HIV-infected persons--Pennsylvania, 1993-1994.
abstract: In April 1993, a man incarcerated in a prison in Berks County in eastern Pennsylvania voluntarily requested testing for human immunodeficiency virus (HIV) antibody and was diagnosed with HIV infection. Following an interview and counseling by Pennsylvania Department of Health HIV Prevention Program (HIVPP) staff (1), he provided contact information about four persons with whom he had shared syringes to inject drugs before incarceration. As a result of follow-up investigation, HIV infection was diagnosed in two of these four persons. One of these two persons provided contact information about 47 partners, including 41 partners with whom he had shared syringes only and six with whom he had had sex and shared syringes. By May 1994, partner notification follow-up of the four partners of the index patient and all subsequently identified partners of HIV-infected persons identified a social network of 124 persons linked by syringe-sharing and/or sex. This report describes the findings of the investigation of this network during April 1993-May 1994 and limited additional information from June-September 1994.
