In the world, economical losses due to the parasitic diseases reach enormous ratios in animal production. Both developed and developing countries set aside a considerable budget to control these parasitic diseases. This situation aids in the improvement of control methods of parasitic diseases. Also, it causes new ways of investigation that includes observation, evaluation and prevention of parasitic diseases. The Geographical Information System (GIS) has recently become one of the most common methods utilized to provide disease information technology with computer supported technology in many countries. The most important qualities of GIS are the formation of a powerful database, continual updating and rapid provision of coordination related to units. Many factors are evaluated at the same time by the system and also, results from analysis of data related to disease and their causes could reduce or prevent economical losses due to parasitic disease. In this study, possible uses of Geographical Information Systems against parasitic diseases and an approach in terms of animal health economics were presented.
