Tuberculosis is one of the most prevalent infectious disease and significant public health problem in Nepal and continues to pose serious threat to the health of the population and development of the country. Currently nearly 80,000 people have tuberculosis in Nepal, with more than 44,000 new cases arising every year. About half of these are infectious (sputum smear-positive) cases which continue the chain of transmission. The majority of TB patients belong to the economically active age groups of 15–45 years.
