This study was conducted to estimate the prevalence of tubercular infection and compute the Annual risk of tuberculosis infection (ARTI) in Bijnor district of western Uttar Pradesh through a hospital-based tuberculin survey conducted at a pediatric hospital. A total of 1085 children below 18 years (0-4 years 866, 5-17 years 219), attending the out-patient department during October 2007 through September 2008 were included. Tuberculin skin test using standard PPD RT23 with Tween 80 was performed on every 4th child attending the out-patient department and induration was measured after 48 to 72 hours. Using a cut-off of 15 mm among 0-4 y aged children, the average prevalence rate was 7.4%, and using cut-off of 10 mm in 5-17 y age group the average prevalence rate was 26.9%. ARTI was 4.11% (95% CI 3.09-5.14) and 3.50 % (2.46-4.48), respectively in the two age groups.
