Objective:

To identify risk factors associated with transmission and mortality specifically in asymptomatic pulmonary tuberculosis (TB) patients.

Key Findings:
  • 36.4% of patients with pulmonary TB were asymptomatic.
  • 25.5% of asymptomatic patients had potential transmission risks.
  • Higher transmission risk associated with male sex (OR 1.385), low BMI (OR 1.687), current smoking (OR 1.443), diabetes (OR 1.399), and autoimmune diseases (OR 2.233).
  • Mortality rate was higher in patients with transmission risk factors (9.3% vs 7.1%).
Interpretation:

Asymptomatic individuals with specific risk factors are significant transmitters of TB and have higher mortality, highlighting the need for targeted screening strategies.

Limitations:
  • Study limited to South Korea, which may not generalize to other regions.
  • Data reliant on self-reported information, which may introduce bias in the assessment of risk factors.
Conclusion:

Targeted screening for asymptomatic TB patients with identified risk factors is essential for controlling TB transmission and improving health outcomes.
