Prevalence of HIV in Patients with Pulmonary Tuberculosis in the City of Bongor in Chad

TB/HIV co-infection is a public health problem in countries with limited resources. The objective of this work was to determine the prevalence of TB/HIV co-infection and to assess the level of contamination of patients screened in each district of the city of Bongor. A prospective cohort study took place from January 2019 to December 2021, in the Department of Phtisiology and the laboratory of the Provincial Hospital of Bongor, including patient files from the 17 districts of the city of Bongor. Ziehl-Neelsen staining and the GeneXpert automaton were used to process and analyze the patients sputum and blood. Epi Info 7™ software facilitated statistical analyses. A total of 320 patients were included in this study. In this study obtained 56.25% of positive sputum and 20.31% of seropositive patients. TB/HIV co-infection was found in 17.19% of seropositive patients. The most co-infected age group was between 32–38, representing 32.73% of patients. TB/HIV co-infected patients by neighborhood represented 0.41% of the inhabitants. The most affected neighborhood was Djoh-Bongor with 0.068%. Conclusion: TB/HIV co-infection in the city of Bongor affects 11 neighborhoods out of 17. The State must provide resources for more awareness-raising in order to stop contamination.
