Materials &Methods: Data on 5743 cases in Razavi Khorasan (Mashhad Medical University Coverage) over 5 years were analyzed. A GIS map is designed to show and compare incidence rate among different regions using ArcGIS software and different correlations between patients specifications are analyzed.

Results: The mean incidence of disease in the province is 26 per hundred thousand people which is highly correlated to animal population of every area. In the first 3 years of study the disease incidence was ascending and in last 2 years it was descending and in May till August the prevalence was more than other months.85% of patients were rural and 15% were urban. 56.9% were male and 43.1% female. Household and farmer-rancher were the most common jobs. Average age of patients was 33.4 ±18.1 year. 77.2% had consumption of unpasteurized dairy products which milk (91.4%) and cheese (21.4%) had the highest consumption. The most common symptoms were fever (79%) and anorexia (47.5%). A significant relationship between location and both livestock vaccination history and also family history, was found.

Conclusion: because of higher incidence rate of the disease in Daregaz, Takhtjolge and Rashtkhar, and young people aged 10 to 30 years and villagers, It’s need to control the disease in these groups.
