Abstract: 

Introduction & Objectives: The World Health Organization estimates that there are at least 170 million children less than 15 years old deaths directly attributable to the tuberculosis in the world. The aim of the present study was to survey the evaluation of benefits of Tuberculin Test for identification of tuberculosis in the children who were vaccinated with BCG vaccine in the high level.
Methods: This study is a cross-sectional descriptive investigation that was performed on children aged 7-11 years old in Tabriz, northwest of Iran, in 2004. Cluster random sampling was used in this study and 1024 cases were participated who received BCG vaccine previously. Tuberculin test was done on the basis of Mantox Skin Test method. The data including age, sex, etc. were gathered through a questionnaire and analyzed using SPSS software system.
Results: All the 992 participants were tested by Tuberculin test (3% were not available). In general 88% of the cases were from urban regions and 12% were from rural areas. 80.5% of the cases had postulations due to BCG vaccine that were injected in childhood. 34.3% had no indurations, but 37.5% had ≥ 10 mm indurations, 16.2% had ≥ 15mm indurations.
Discussion & Conclusion: Significant difference was observed in indurations diameter of participants (P<0/05). Significant differences were also observed among indurations diameter, age, places of birth, BCG postulation and response to Tuberculation reactions of participants (P<0/0001). Our results in this study showed that Tuberculin Test (Mantox Skin Test) could be a useful method for identification of tuberculosis infections in high risk societies using high level of BCG vaccination.
