Considering the importance of this study, the aim of this study was to determine the prevalence of brucellosis in Kohgiluyeh and Boyer Ahmad Province in 2017. Materials and Methods: This retrospective cohort study was conducted to determine the rate and causes of brucellosis in Kohgiluyeh and Boyer Ahmad province in 1396. Sampling was done by census.

In order to collect data from a researcher-made list, data collection for brucellosis patients was used. Descriptive statistics and SPSS 21 series software were used to analyze the data. Results: 17 cases had negative test. The highest number of occurrences in 2016 was 143 cases and the highest occurrence was 171 in the spring. Boyer Ahmad city has the highest rate with 107 cases and Bahmei city with the least amount of brucellosis in 9 cases. 360 people were from rural population.

The prevalence of this disease depends on the number of livestock and the absence of complete animal vaccination (2). Among the various causes of brucellosis, the most common cause of the bacterial pathogenicity of the coccobacilli is germicide of the invasive Brucella National Tenissi (3). Communication and consumption of animals such as sheep, dogs, camels and cows, dolphins and eel can provide conditions for the disease in humans (4). Brucellosis can even survive in dairy products for a long time, causing contamination and disease in humans (5). Human involvement with brucellosis is very important both in terms of health and economics (6). Due to the inaccessibility of accurate data on the extent of infection, there is no accurate statistics on the distribution of this disease in the world (7). In Iran, the number of cases of brucellosis has been estimated to be around 25% per 100,000, which is declining annually (8). Brucellosis is present in various parts of the world, especially in the Mediterranean, the Middle East, the Arabian Peninsula, Central and South America, Asia and Africa (9). In countries like the United States, the disease is considered a work hazard (10). The most frequent season that this disease may develop is spring and summer, and it is seen in rural areas more than urban areas (11). In Iran, there are concerns about the disease in the western regions (12). Kohgiluyeh and Boyer Ahmad province, in terms of geographical location and its
