A sample survey was carried out in the North Arcot district of Tamil Nadu with the objective of finding out the prevalence of bacteriologically positive and radiologically active pulmonary tuberculosis among persons aged 15 years and above using two screening methods viz.. elicitation of suggestive symptoms and chest X-ray examination. Another objective was to estimate the prevalence of tuberculosis infection in children aged below 10 years. A population of 1,05,339 persons was registered in a random sample of 35 villages from the rural areas and 102 town streets from the urban sector. All children aged 0-9 years were tuberculin tested with ITU RT23. Persons aged 15 years and above were screened for suggestive symptoms. and one-third of the sample was screened by X-ray of chest as well. Sputum specimens from the symptomatics and/or X-ray abnormals were subjected to bacteriological examination. The prevalence of infection among ‘below 10 years old’ children without BCG scar was 6.7%. The prevalence of disease by sputum smear and/or culture among symptomatics was 4.3 per thousand in population aged 15 years and above. The prevalence rate of bacteriological positives based on symptoms and X-ray screening, in the one-third sample was 7.9 per thousand. The prevalence of X-ray positive cases was 17.0 per 1000. Information available from similar other studies in the country has been reviewed.
