|Brucellosis is one of the most prevalent bacterial zoonotic diseases considered as a public health problem in Golestan province (north-east of Iran), but its spatial pattern remains unclear. Hence we evaluated the spatial analysis of brucellosis disease in Golestan province during 2015-2017. In this study, we explored the Spatial and Spatiotemporal clusters by using scan-statistic to consider influencing factors. In addition, logistic regression and Pearson’s chi-square tests were used to analyze the clusters' zones and compare them with others. We used GIS to determine unites' (Golestan cities) coordinate centers and visualize the location of the clusters. Results revealed that the geographical distribution of brucellosis in Golestan province was affected by several spatial and spatiotemporal clusters. Constituent units of both spatial and spatiotemporal clusters were the same, but the identified time period of spatiotemporal clusters was from January 2015 to June 2016. The main influencing factors were in contact with livestock and dairy hygiene. This study can assist health authorities to plan more effectively to control diseases by highlighting the high-risk areas and behaviors.|

Brucellosis is a prevalent bacterial zoonotic disease, which is an important health burden causing an abortion in animals as well as a fetal multi-system sickness in human beings. WHO reports that there are more than 500,000 cases of brucellosis worldwide diagnosed annually, especially in the developing countries, while four cases remain undetected per a diagnosed case (Zeinalian Dastjerdi et al., 2012). Common symptoms of brucellosis are fever, night sweating with a peculiar odor, chilling, weakness and malaise, arthralgia, constipation, sexual impotence, being nervous, insomnia, anorexia, headache, and depression (Seleem et al., 2010). Simple infections of brucellosis without complications can usually be treated successfully with antibiotics, which the therapy often takes several weeks to months, although relapsing is common. (Von Bargen et al., 2012) Despite a well-established Primary health care system (PHC), Iran is one of the top five countries with a high incidence rate of brucellosis disease, especially in rural areas (Haghdoost et al., 2007). Socio-economic and environmental conditions, as well as brucellosis distribution in a community, can influence the incidence rate strongly (Mirnejad et al., 2017). Most parts of Iran are endemic for the disease, particularly the areas where humans live in close contact with livestock (Sofian et al., 2008). The prevalence of human brucellosis depends on factors such as socioeconomic situation, environmental hygiene, dietary habits, husbandry practices, methods of processing milk, and dairy products (Gwida et al., 2010). There is a considerable variation in the prevalence of brucellosis in different parts of Iran, and the incidence rate differs from 98 to 130 per 100,000 of the total population. The
Spatial analysis approach
Brucellosis may lead to severe morbidity, and it has been an important health concern in the north-east of Iran (Golestan province). As there is no recommended treatment for complicated forms yet, it is necessary to plan multicenter studies with more cases to reach better therapeutic choices, especially in these types.
