Peste des petits ruminants (PPR) is one of the most important infectious diseases of livestock. This disease is endemic in Iran. The aim of this study was to use GIS to help control PPR over an eight-year period in Kermanshah province. Reports of PPR disease in Kermanshah province were collected over a period of 2011-2019.

The total number of livestock   infected, mortality and high risk centers were added to the descriptive table and It was connected to the province map using the Geographical Coordinate System. .Data analysis was performed based on the difference between disease incidence points, incidence rates and areas of Kermanshah province using SSPS 18 software and Fisher chi-square test.: There was a significant difference in disease incidence in different parts of the province (P <0.05). In conflict and infection centers, the highest and lowest statistics were related to the western region with 39.4%, the central region with35.9% and the eastern region with 24.6%, respectively.
