Background: Despite substantial efforts to control the disease, brucellosis remains one the most rampant zoonotic infections among agricultural and rural populations. It is still considered a major public health challenge in endemic areas including Iran.

Objectives: regarding high prevalence rate of brucellosis in north-west of Iran and the occupational nature of the disease, this study intends to describe epidemiological pattern of brucellosis in Salmas, Iran, during 2014-2017.

Methods: this cross-sectional study was conducted on the data collected using a checklist designed to investigate personal health records of patients available at Urmia University of Medical Sciences from 2014 to 2017. Data analyses were conducted using version 19 of SPSS software. Chi-square, t-test and the Cochran-Armitage χ2 test for trend were performed.

Results: Among 417 brucellosis cases, the total incidence rate was 52.73 cases/100,000 inhabitants over the 4-year study. The prevalence rate of brucellosis was higher in males and the male to female ratio was 1.38. The most infected age group was of 31-45. The summer season showed higher prevalence. Brucellosis was more common among Housewives-stockbreeders. Cheese was the most frequently consumed unpasteurized dairy product. The majority of patients were from rural regions.

Conclusion: the study shows a statistically significant increase in the prevalence of human brucellosis in Salmas, hence the disease has to be regarded as a public health priority. Educating farmers and inhabitants of endemic areas to take preventive measures can play a significant role in controlling brucellosis.
