Materials and Methods This cross – sectional study was carried out on children under 15 years old in Hamadan province during 2012-2014. 460 patients in this period were investigated. Data were analyzed using by descriptive statistics and incidence rate as an analytic statistics with Stata software version 12. P-value≤0.05 considered as statistically significant. Results Overall 460 Brucellosis cases were detected in children during the studied period, among them N (%) of boys and reside in rural area were 317 (68.9) and 404 (87.8) respectively.
