Abstract

A tuberculin survey was conducted in selected clusters of 26 districts in four defined zones of India. Children 1–9 years of age were subjected to tuberculin testing with 1TU PPD RT23 with Tween 80, and the maximum transverse diameter of induration was measured 72 h later. Prevalence of infection was estimated using the cut-off point method (Method I) and the mirror-image technique (Method II) among children without bacille Calmette-Guérin scar. Results from individual zones have been reported earlier, and the results from all four zones are presented here as a consolidated summary.
