This paper reports the studies conducted in India by different agencies on prevalence of tuberculosis (TB) disease in different parts of the country at different points of time. Epidemiological investigations are undertaken to detect the changing trends in the incidence and prevalence of TB in a community. The three major tools for the study of epidemiology are: sputum examination (microscopy and culture), mass radiology and tuberculin testing. The first nationwide TB prevalence survey was conducted by Indian Council of Medical Research (ICMR) during 1955-58 in sixselected zones of the country. Thereafter, National Tuberculosis Institute (NTI) conducted a disease prevalence survey in Tumkur district and another with four rounds of disease surveys in rural areas of Bangalore as part of a longitudinal study. This study gave vital information on various aspects of epidemiology of the disease and its trend. The summarised findings of these and various other surveys carried out in India from the early 1950's to 1997 give valuable information on the burden of TB in India.
