Brucellosis with decreasing productivity, abortion and weakness in cattle and disability, causes a dramatic drop in the economic and social capital of countries. Since the province of Markazi was considered as a high infection regions, therefore, the aim of this study was to evaluate the epidemiology and incidence trend of disease in the Khomein (2014-2016). This descriptive-analytical study was carried out in the city of Khomein, using data from the national program of brucellosis. The statistical population consisted of patients with brucellosis, whose information was recorded. To calculate the age-standardized incidence rate (ASR) was using the world standard population. Data were analyzed using SPSS-20 software. The mean age of patients was 40.9 ± 19.1 years. During this period, the average annual incidence rate (IR) of the disease was 61.8 and the mean age-standardized incidence rate (ASR) was estimated to be 56.16 per 100,000 people. 62.7% of the patients were male and 88.7% were rural residents and there was no significant difference between the two variables (P = 0.26). Farmers-rancher occupations (25.5%) and housekeeping (18.6%) had the most cases. Most people are in the third and sixth decades of life. The majority of patients (87.7%) had a history of animal contact as a risk factor expression. Muscle pain and back pain (92.6%) were the most common cause of referral. Despite the slow decline in the disease process, the Khomein province is from infected areas and high-risk of the disease in the country. It seems that changes in the pattern of transmission and the risk disease from food to work are ongoing, which requires the attention of health politicians to carry out appropriate interventions such as Correct implementation the SHEP program to reduce the incidence of brucellosis.
