SUMMARY About 57 per cent of our present old aged population are infected with tubercle bacilli. There has been an appreciable reduction in the reservoir of tuberculosis during the interval of ten years. More men than women react to the tuberculin test among the aged. Although a gratifying reduction of the tuberculosis reservoir is noted, tuberculosis among the elderly remains a major problem. Retesting with tuberculin of this age group after a period of ten years would give us a new index of tuberculosis infection.
