Brucellosis is a major problem in many parts of the world, including Iran, where livestock are an important source of income and employment.
This cross-sectional (descriptive-correlational) study enrolled individuals diagnosed with brucellosis from 2012 to 2016 and their information was available in the health center of Kermanshah province. Data were analyzed in SPSS software (version 21).
From all the patients with brucellosis (2714), 55.3% were male and 44.7% were female. Most of them were living in Kermanshah province, their mean age was 35.05 ± 17.35 years and the most common age group was 21 - 30 years. The most common route of transmission was consumption of contaminated dairy products (99.1%) and contact with livestock (99.71%). Musculoskeletal and back pain were the most commonly observed clinical signs (89.8%). There was a statistically significant difference between years of incidence and livestock vaccination history (P < 0.001). The highest number of patients wright test was in titer 1:160 (33.1%) and 2 ME test 1:80 (36.8%). Regarding the use of medication for treatment, most patients were prescribed combination of rifampin and co-trimoxazole (12.97%).
Timely diagnosis, livestock vaccination, training and refraining from unpasteurized dairy products can be effective in preventing outbreaks of brucellosis.
