Estimates of the prevalence of tuberculous infection among children 1–9 years of age were available for four defined zones of India from a recently concluded tuberculin survey. These were pooled together and the average annual risk of infection in the country was computed as 1.5%. It was higher in urban areas, at 2.2%, than in rural areas, at 1.3%. The results call for further intensificationof tuberculosis control activities, especially in urban areas, greater involvement of private practitioners and information, education and communication (IEC)for high-risk groups, to reduce the diagnostic and treatmentdelay thereby reducing the transmission of infection in all settings.
