Screening of human immunodeficiency virus infection in pulmonary tuberculosis patients in Taiwan.

To disclose the impact of human immunodeficiency virus (HIV) infection on the tuberculosis epidemic in Taiwan, we prospectively screened for HIV infection in patients with active pulmonary tuberculosis. A total of 378 patients who were admitted to the Taiwan Provincial Chronic Disease Control Bureau from January through December 1996 were enrolled. HIV serologic testing was performed by enzyme-linked immunosorbent assay (ELISA). A positive ELISA test was confirmed by Western blot analysis. One patient was infected with HIV. We conclude that the impact of HIV infection on the epidemic of tuberculosis in Taiwan is not significant at present.
