Methods: In ths study, nformaton about the new cases of acute flaccd paralyss whch were provded by Management Center of Mnstry of Health and Medcal Educaton n 8 (006) were analyzed. Posson Mxture dstrbuton was used to fnd out the number of at rsk groups. Number of components and parameters of each component were found by nonparametrc maxmum lkelhood method usng the C.A.MAN software. Bayes theorem and programs whch are wrtten n the R.8.0 software were used to assgn each provnce to a parameter. Fnally the results were shown on the map usng ArcGs9.. Results: The results show that the ncdence of acute flaccd paralyss can be classfed nto four categores, each havng ther own specfc rsk and probablty. Concluson: Ths study showed that Mxture models can be used to accurately map acute flaccd paralyss n Iran.
