Abstract
INTRODUCTION: Brucellosis is communicable between humans and animals. In spite of having an active health care system. Iran is considered as an endemic area and it stands in the fourth place in world ranking. One of the common methods for identifying the disease incidence is a regression analysis. Therefore, the aim of the study was to investigate the trend of brucellosis incidence during 2006 to 2016 and the components affecting such disease. MATERIALS AND METHODS: This was a trend study which was conducted on the total of 144 brucellosis cases were recorded in the registration software in CDC of Iranian, Ministry of Health. We analyzed the changes in brucellosis incidence during 2006 to 2016 in Juybar province by the join point regression. Moreover, comparing the changes of incidence in one year intervals was also taken into account. RESULTS: The average age of patients was 18±29 years. About 60% of the patients were men, and 85.4% had used non-pasteurized dairy and meat products. The contact with animals had a significant difference between the two genders (P= 0.006). During 2006 to 2016, brucellosis incidence had a decreased trend about 15%. This trend had a breakpoint in a way that during 2006 to 2008, 66.2% decrease and during 2008 to 2016, 7% increase was observed that none of these annual percentage changes (APC) were statistically significant at p= 0.05. Also, APC of brucellosis incidence in groups below 20 and between 20 to 50 years old had a decrease in a way that in groups under 20, it had 26.7% decrease and it was statistically significant. CONCLUSION: It is necessary to provide appropriate education training, information on the Human Brucellosis for the young and individuals with high risk professions. Moreover, some health behaviors such as not using non-pasteurized dairy, animals' vaccinations, and awareness of the disease symptoms are needed.
