[Tuberculosis and HIV infection in the Kweneng district, Botswana].

The prevalence of HIV infection in a group of Botswana tuberculosis patients was studied in a linked, anonymous survey that included 214 cases. The testing was done by ELISA serology. 45 of 214 patients (21%) were HIV positive. The HIV seropositivity reached 29% in the age group 15-49 years. 25% of the females (average age 34 years) and 18% of the males (average age 39 years) were HIV positive. 18 (40%) of the 45 HIV positive patients had AIDS. No significant differences were found between HIV positive and HIV negative patients with regard to clinical type of tuberculosis. The findings are discussed in relation to other studies from Africa.
