Abstract: In this study, we investigated the spatial distribution of CCHF incidences of Tokat Province within the frame of Geographic Information Systems (GIS). For this purpose, we evaluated the public health data collected between 2003 and 2006. Frequency data that belongs to 133 settlements was joined to the referenced point database of Turkey in GIS and interpolated to raster maps by employing Kriking method with Spherical variogram model. Produced raster maps of each year and combination of all years were interpreted visually. Relationships between incidence and other available variables (population, elevation, cattle number, sheep and goat number) were investigated by employing bi-variety correlation analysis (Pearson coefficients). According to the results, CCHF events in Tokat increased from 50 to 100 within the 4 years and showed the tendency to spread in certain geographic locations of the province. CCHF incidence and elevation showed significant (positive) correlation (0.687) at 0.05 level under an altitude threshold (1340 m).
