Abstract：We investigated the present epidemic status of human parasitic diseases in Fujian Province. According to the unified methods formulated by the national investigation scheme and stratified cluster random sampling, 15 counties were selected in Fujian Province. Five pilots were selected in the county. The number of the subjects investigated in individual pilot was defined over 250. The cyst and trophozoite of intestinal protozoa were examined by method of direct saline smear and iodine staining. In addition, Kato-Katz thick smear was applied to detecting the eggs of intestinal helminthes. Results showed that altogether 75 pilot sites of 15 counties were selected and clustered random sampling. A total of 10 652 people were detected, and 222 people was positive, six species of intestinal protozoa were identified and infection rates were as follows: Blastocystis hominis (0.79%), Endolimax nana (0.58%), Entamoeba coli (0.41%), Entamoeba hartmanni (0.18%), Entamoeba polecki (0.09%), and Giardia lamblia (0.02%). The infection rates were 0.84% and 1.25% in males and females, the later was much higher than the former (P<0.05). The eldest infection was 86, the youngest was 3. The infection were mainly in high age group (38.3%), which was above 56 years old. The infection were distributed in many occupations, among which 77.9% were peasants, 14.4% were students. The rate of regional infection in Pingtan was the highest, followed by Zhangpu 4.62%, Zhouning 3.92%. The infection rate of ecological functional areas was 1.52% (83/5 469) in hills of Zhejiang and Fujian, 2.68% (139/5 183) in the middle of Southern hills of Yunnan, Guangxi and Guangdong. And the difference was statistically significant (χ2=17.674, P<0.01). The total infection rate of protozoa was greatly reduced in this investigation. And the number of infection species was decreased. Blastocystis hominis,the common intestinal protozoa should be listed as the focus of future control.
