Ten-year summary of human immunodeficiency virus serology in west Tennessee.

Abstract

Since the isolation of human immunodeficiency virus (HIV), numerous laboratory tests have been developed to confirm the immunologic response to the virus. In 1991, the state of Tennessee mandated that clinical laboratories performing Western blot analyses for HIV report all new cases of confirmed HIV infection. This report is a summary of HIV confirmed cases evaluated by this facility from 1985 until July 1, 1995. During each year, the laboratory screens approximately 20,000 persons for HIV and all positive screens are confirmed by an FDA-approved Western blot. During the period described, the laboratory has confirmed HIV serologic positivity in 4,096 individuals, principally from Shelby County and surrounding Tennessee counties. Although these data are not complete, they clearly indicate that we have a continuing problem with this infectious disease. Based on the current rate of positive cases seen thus far in 1995, this facility may confirm nearly 900 new cases of HIV infection in this year alone.
