Background:
This study aims to determine the prevalence of TB among ambulatory people living with HIV in Guangxi Province, which experienced the biggest HIV epidemic in China.
Methods:
We undertook a longitudinal study in five HIV/AIDS designated hospitals randomly selected from Guangxi Province; all newly diagnosed HIV/AIDS outpatients from 2019 to 2021 were screened for TB and interviewed with a questionnaire.
Results:
A total of 4539 HIV/AIDS outpatients were enrolled, with 2886 (63.6%) men and 1653 (26.4%) women. The prevalence of TB/HIV coinfection was 0.8%, with a clear downward trend from 1.3% in 2019 to 0.4% in 2021 (p = 0.0011). The prevalence of LTBI was 24.3%, with no significant differences from 2019 to 2021. The percentages of AIDS, comorbidity, nine symptoms and abnormal chest X-ray of TB were higher than those of the other PLWH.
Conclusion:
The prevalence of TB among ambulatory people with HIV in Guangxi Province was 14 times higher than the general population, and the annual declined TB prevalence indicated the effectiveness of TB and HIV control and prevention over recent years. The findings proved that symptom screening was insufficient for TB diagnosis and highlighted the importance of systematic TB screening at every visit to a health facility.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
