Abstract: 

Amebiasis caused by Entamoeba histolytica is cosmopolitan in distribution. Aproximately 80% of the morbidity population are without any signs. A recent estimate is that there are about 500 million infected individuals worldwide, with an annual mortality rate of 75000 to 11OOOO. It is caused the third mortality after Malaria and Schistosomiasis in the world. In this research, we will be determining prevalence rate (PR) of intestinal amoebiasis (IA) and related factors such as age and sex in villages of Sarakhs.
The type of study was Cross-sectional. PR of disease was determined by 250 samples of stool from three villages (one located in flat, the other in slope and tertiary located in mountain area.( Total 250 persons were studied in three villages. (100 in flat area, 88 in slope and 62 in mountain area). In this study, no acute amoebiasis was seen. PR of IA was 7.2 percent. Because all of cysts positive were in flat area, hence PR of IA in this village was 18 percent. Proportion of infected in male was 11.9 percent and in female 22.4 percent. Sex differences of infected persons were not statistically significant (P>0.05).
The highest proportion of infected age group was 5-9 year. Mean of age of infected persons was 22.7 years (standard deviation=17.3) and in other was 24.1 years (standard deviation=28.1). Differences of mean of age were not statistically significant (P>0.05).
Occurrence of Amebiasis is worldwide. The most infected areas in the world were Asia and Africa. PR of amebiasis in cities of Iran is 6-8 percent and in rural areas 5 to over 30 percent Total PR of IA was 7.2 percent. Lack of infected person in later villages for many reasons especially sanitary water availability in these areas. Differences of Proportion in male and female groups were not statistically significant. (P>0.05) This result is consistent with other studies. In this study, most of cases were seen in 5-9 year age group. Whereas other studies showed that, most of cases occur in 20-40 years. As a result, for control of the disease, water sources and other public finances must be care intensively.
