Background: The purpose of this study was to determine the epidemiological characteristics and incidence rate of brucellosis in the Tiran-Karvan Township in Isfahan province, Iran, during 1999-2012. Methods: This cross-sectional study was performed on all patients with brucellosis in public and private sectors of the Tiran-Karvan Township from 1999 to 2012, which had completed brucellosis form. The incidence density rate was calculated and reported based on total person-years in study duration. Findings: The mean incidence density rate in a 14-year period was 52.96 per 100000 person-years. This rate was 5.67 in urban area, and 52.54 in rural area. The highest incidence was in people employed in agriculture and animal husbandry and the least level was for students. Besides, the highest incidence rate was in spring and the least in autumn as 26.69 and 2.44 per 100000 personyears, respectively. Conclusion: The mean incidence of brucellosis in the Tiran-Karvan was higher than province average and the trend of its incidence was rising. However, the disease is much more common in rural than urban areas. © 2014, Isfahan University of Medical Sciences(IUMS). All rights reserved.
