Samples of 744 person from 14875 population of 17 villages in plane area and 502 persons from 10031population of 11villages in forest area (1246 person in total) that was 5% of the total population of two regions were collected. In this study the percentage of infection with intestinal parasites for age, sex, literacy, area condition (plane -forest), and the type of drinking water (pipeline - nonpipeline) was determined. The laboratorial diagnosis of the stool sample was performed by two methods the direct method and the formalin - ether - method. The prevalence of infection with all parasites in two areas was 43.9%, that infection with pathogenic parasite was 28.25% the most prevalence of infection with intestinal protozoa was for Giardia lamblia (17.82%) that the highest percentage of infection was in housewives (20.43%) . The prevalence of infection with Entamoeba histotytica was 4.97%. The prevalence of other intestinal protozoa was found as below: Entamoeba coli 6.82% , Iodamoeba butschli 1.68% , Endolimax nana 6.09% , Blastocytis hominis 8.19% , Chilomastix mesnili 1.12%. The most prevalence of infection with Hymenolepis nana (3.61%) that the highest rate was found in animal husbandmen. The prevalence of infection with Hook worms (2.25%) was in the next range that the highest percentage of infection was found in farmers especially in rice farmers. The prevalence other intestinal parasites was found as below: strongyloides stercoralis 1.0-1%, Enterobius vermicularis 0.32%,Trichostrongylus 0.24%, Ascaris lumbricoides 0.4%.
