HIV seroprevalence in hospital patients in rural Georgia.

To determine human immunodeficiency virus (HIV) seroprevalence among hospital patients in three rural community-based hospitals in southern Georgia, we anonymously tested patients 15 to 54 years old for antibodies to HIV-1 from residual blood specimens collected for routine diagnostic purposes. Data collected included age, sex, race, hospital service, presenting condition, physician's knowledge of HIV infection status, and discharge diagnosis. Of 1319 patients tested, seven (0.5%, 95% confidence interval = 0.2% to 1.1%) had antibodies to HIV-1. Of those seven, five had HIV infection unsuspected by their physicians, and four had an infectious disease. HIV seroprevalence was 0.5% for both men and women, 1.0% for blacks, and 0.3% for whites. HIV-positive patients were found on all hospital services. These results suggest that in rural southern Georgia hospitals, HIV should be routinely considered in the differential diagnosis of conditions that may be related to HIV. In addition, these data demonstrate a need for medical services or referral networks for HIV-related illnesses and a need for continuing HIV counseling and testing offered by local health departments in rural southern Georgia.
