Tuberculosis (TB) disproportionately affects older males in Nepal, with higher rates of smear-positive cases. Controlling this pulmonary TB burden presents significant challenges for low-middle income countries.
Area of Science:
- Global Health
- Infectious Diseases
- Public Health
Background:
- Tuberculosis (TB) is a leading global cause of death, exacerbated in Nepal by poverty and malnutrition.
- Sputum identification of *Mycobacterium tuberculosis* is crucial for diagnosing pulmonary TB.
Purpose of the Study:
- To investigate the prevalence, burden, and challenges of pulmonary tuberculosis in Nepal.
- To analyze demographic and diagnostic factors associated with pulmonary TB in a low-middle income country.
Main Methods:
- A retrospective audit of one year of secondary data was conducted (n=4131).
- Descriptive analysis (frequency, percentage) and inferential statistics (chi-square test) were employed.
- Significance level was set at p < 0.05; ethical approval was obtained.
Main Results:
- Pulmonary TB prevalence was highest in individuals over 60 years (32.54%) and lowest in those 15 years or younger (5.79%).
- Males had 1.67 times more smear-positive pulmonary TB cases.
- Among AFB-positive cases, smear 3+ was most frequent (38.54%), followed by smear 1+ (31.28%) and smear 2+ (30.16%).
Conclusions:
- Smear-positive pulmonary TB is more prevalent in males, with a higher intensity (smear 3+) observed.
- Adults and the elderly bear a greater burden of pulmonary TB.
- Controlling pulmonary TB poses a significant challenge for developing nations like Nepal.

Pulmonary Tuberculosis I
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.
