Background:
Tuberculosis (TB) remains a significant public health challenge in India, particularly among vulnerable populations. The Saharia tribe, a Particularly Vulnerable Tribal Group (PVTG), faces a disproportionately high TB burden. This study aimed to systematically review and quantify the TB burden among the Saharia tribe through meta-analysis.
Methods:
A comprehensive search was conducted in PubMed, Embase, Scopus, and Web of Science databases. Studies reporting TB prevalence in the Saharia tribe were included. The quality of included studies was assessed using the JBI Critical Appraisal Checklist. A random-effects model was used to estimate the pooled TB prevalence. Heterogeneity was assessed using I2 statistics, and publication bias was evaluated using funnel plots.
Results:
Eight studies encompassing 163,562 Saharia individuals were included. The pooled TB prevalence was 2,416 per 100,000 population (95% CI: 1,827-3,004 per 100,000). Significant heterogeneity was observed (I2 = 98.67%, p < 0.05). Sensitivity analysis revealed no significant influence of individual studies on the overall prevalence estimate.
Conclusion:
This meta-analysis reveals an alarmingly high TB prevalence among the Saharia tribe, far exceeding the national average. These findings underscore the urgent need for targeted interventions, improved healthcare access, and culturally sensitive TB control programs for this vulnerable population.

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.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
