Abstract:
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 intensification
of 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 treatment
delay thereby reducing the transmission of infection in all settings.
