Prevalence of pulmonary tuberculosis in far Western Nepal.
Keeping in view of high prevalence of tuberculosis in far western development region in different reports, a door to door survey of 125 household was carried out randomly in Mahendra Nagar municipality ward no 13 of Kanchanpur district to pick up symptomatics suggestive of pulmonary tuberculosis and find the prevalence in the target population. A total of 200 sputum specimens from 70 symptomatics within the age range of 10-80 years were collected and subjected to smear microscopy by Ziehl - Neelsen's method. Out of 10 positive cases (14.28%), infection in males and females was 80% and 20% respectively. The infection was found in the productive age group 20-69. The highest prevalence was obtained in 20-29 age group (25%) followed by 40-49 (11%), 30-39 (9%), 50-59 (8%) and 60-69 (8%). The diagnostic yield of single sputum specimen examined was insufficient in field condition, especially where the sputum positivity was low. Of the three sputum smears examined, the early morning specimen had the best result.
