Abstract :

Tuberculosis occurs world wide and remains an important cause of morbidity and mortality in many countries.In 2013 there were an estimated 9 million new cases of tuberculosis and an estimated 11 million prevalent cases causing death to 1.5 million people globally. There were an estimated 2.2 million (26% of the total cases) new cases in India and 0.28 million people died in our country due to tuberculosis in 2013. It is a cause for concern as India stands first in terms of absolute number of cases, closely followed by China (1). It is a real paradox because pathogenesis, transmission, prevention, diagnosis and specific therapy are all well known for tuberculosis.
