Prevalence of human immunodeficiency virus among pulmonary tuberculosis patients: A cross-sectional study.

Tuberculosis (TB) is caused by Mycobacterium tuberculosis and is an endemic disease in Sudan, where it has rapidly become the major complication of human immunodeficiency virus (HIV) infection. Thus, this study aimed to determine the prevalence of HIV among TB patients and evaluate the co-infection rate. The association of HIV prevalence with gender, age, and duration of treatment as risk factors was also determined.
