Abstract

The trend of tuberculosis in a sample of 22 villages observed over a period of about 16 years (1961-77). is reported. Distributions of tuberculin indurations did not show a clear cut demar-cation between infected and non-infected. The choice of demarcation level, therefore, is somewhat arbitrarily made on the basis of the distributions and these varied from survey to survey; between 10 mm at survey I and 16 mm at survey V. The method adopted to demarcate the cut off point has been described in detail. The actual and standardised infection rates showed more or less declining trend in 0-4 years, 5-9 years and 10-14 years age groups, The prevalence of cases was not significantly different from survey to survey (varying from 3.96 to 4.92 per thousand from first to fifth survey). How-ever, there was a shift in the mean age of cases, and better survival rate of cases diagnosed at later surveys.
