A South Indian village population of about 40,000 was examined by X-ray in 1950-51 at the start of an intensive tuberculosis control campaign. By comparing the prevalence of X-ray positive cases suggestive of active or probably active pulmonary tuberculosis as found by a new and independent reading of the 1950-51 films with that obtained by a survey done in 1957-58, children below the age of 10 showed a decrease whereas there was no change, or a small but statistically insignificant increase in the rest of the population. The absence of a decrease in the adults is ascribed to the result of.keeping patients alive who would have died if they had not been treated with antibiotics and the fact that the great majority of fresh cases arising since 1950-51 were already infected with tubercle bacilli before the control campaign began.
