An epidemiological survey was made on human intestinal protozoa in Xinjiang Uygur Autonomous Region (Xinjiang) to evaluate recent control achievements and provide basis for making specific control strategies.
Regions in Xinjiang were categorized by types of ecological system and geographical characteristics into five ecological areas（types I-V） according to the National Ecological Function Stratification issued by the Ministry of Environment Protection and Chinese Academy of Science and Technology. Stratification sampling was made in each ecological area. Feces from human of all ages were collected for morphological identification of protozoan species using the Iodine Liquid Direct Smear Method.
In the five ecological areas, 26 886 people from 132 survey sites in 39 counties (cities) were examined, with an examination rate of 81.47% （26 886/33 000）. The infection rate was 0.32%（85/26 886）. Four species of intestinal protozoa were detected, i.e., Entamoeba histolytica, Giardia lamblia, Blastocystis hominis, and Entamoeba coli, with an infection rate of 0.22% （60/26 886）, 0.03% （9/26 886）, 0.01% （2/26 886） and 0.61% （17/26 886）, respectively. Of the five areas, the type IV area had the highest infection rate of 0.75%（28/3 758）（P<0.05）. Besides, the infection rate was higher in males （0.24%, 33/13 623） than that in females （0.39%, 52/13 263） （P<0.05）, higher in age ranges of 21-30（1.40%, 16/3 959） and 31-40 years（0.46%, 22/4 799） than other age groups （P>0.05）, higher in housewives （0.48%, 2/418） than those with other occupations, higher in the Hui group （0.61%, 15/2 445） than that in other ethnic groups, as well as highest in populations with a primary education level （0.37%, 35/9 375） and lowest in those with a college level or above（0.20%, 8/3 945）.
The human intestinal protozoa infection was at a low level in Xinjiang in 2015.
对新疆维吾尔自治区人体肠道原虫进行流行病学调查，以评估近期防控成效，为制定针对性防控策略提供依据。
依据环境保护部和中国科学院发布的《全国生态功能区划》，按照生态系统类型和地理特征，将新疆地区划分为五个生态区（Ⅰ - Ⅴ型）。在每个生态区进行分层抽样。采集各年龄段人群粪便，采用碘液直接涂片法进行原虫种类的形态学鉴定。
在五个生态区，对39个县（市）132个调查点的26886人进行了检查，检查率为81.47%（26886/33000）。感染率为0.32%（85/26886）。检测到四种肠道原虫，即溶组织内阿米巴、蓝氏贾第鞭毛虫、人芽囊原虫和结肠内阿米巴，感染率分别为0.22%（60/26886）、0.03%（9/26886）、0.01%（2/26886）和0.61%（17/26886）。五个区域中，Ⅳ型区感染率最高，为0.75%（28/3758）（P<0.05）。此外，男性感染率（0.24%，33/13623）高于女性（0.39%，52/13263）（P<0.05）；21 - 30岁（1.40%，16/3959）和31 - 40岁年龄组（0.46%，22/4799）的感染率高于其他年龄组（P>0.05）；家庭主妇感染率（0.48%，2/418）高于其他职业人群；回族感染率（0.61%，15/2445）高于其他民族；小学文化程度人群感染率最高（0.37%，35/9375），大专及以上文化程度人群感染率最低（0.20%，8/3945）。
2015年新疆人体肠道原虫感染处于低水平。
