摘　　要：目的了解海南省人体重点寄生虫感染现状和流行特征,为制定全省寄生虫病防治策略提供科学依据。方法2015年按照《全国第三次人体重点寄生虫病现状调查实施细则》,采用分层整群随机抽样的方法从海南省8个市(县)中抽取10个行政村和8个城镇为调查点。所有调查点均开展土源性线虫感染、带绦虫感染调查,仅在行政村调查点开展肠道原虫感染调查。每个调查点抽取3岁及以上常住居民不少于250人。采集受检者粪样,采用改良加藤厚涂片法(Kato-Katz法,一粪二检)检查肠道蠕虫卵,试管滤纸钩蚴培养法鉴别美洲钩虫和十二指肠钩虫,透明胶纸肛拭法检查3~6岁儿童蛲虫卵和带绦虫卵,生理盐水和碘液直接涂片法检查肠道原虫滋养体和包囊。采用SPSS 21.0软件对数据进行统计分析。结果共调查8个市(县) 18个调查点4 773人,总感染率为13.3%(633/4 773)。其中原虫感染率为2.8%(76/2 698),检出原虫5种;蠕虫感染率为12.1%(576/4 773),检出蠕虫7种,主要为钩虫(5.6%)和鞭虫(4.3%)。252名儿童接受透明胶纸肛拭法检测,蛲虫感染率为31.4%(79/252),无带绦虫感染。共有143例钩虫感染者阳性粪样进行钩蚴培养,其中美洲钩虫感染120例,美洲钩虫和十二指肠钩虫混合感染23例。行政村、城镇调查点蠕虫感染率分别为18.1%(488/2 698)、 4.2%(88/2 075)(P <0.01)。男性、女性蠕虫感染率分别为10.9%(247/2 273)和13.2%(329/2 500)(P <0.05);60~69岁年龄组蠕虫感染率最高(17.6%, 77/438), 15~19岁年龄组最低(6.2%, 12/194),各年龄组之间感染率差异有统计学意义(P<0.01);苗族蠕虫感染率最高,为19.1%(97/508),不同民族间差异有统计学意义(P <0.01);蠕虫感染率职业分布以农民最高(14.1%, 384/2 717),商人最低(3.5%, 8/228),不同职业间差异有统计学意义(P <0.01);文化程度分布以文盲感染率最高,为20.8%(33/159),大专及以上学历感染率最低,为5.8%(34/591),不同文化程�Objective To understand the current status and trends of human important parasitic diseases(HIPD) as a basis for their better control, a survey was carried out in Hainan Province in 2015. Methods According to the Protocol of the 3 rd National Survey on the Status of Human Key Parasitic Infections. Total 18 survey sites(10 villages, 8 townships) were selected from 8 cities(counties) using a stratified random sampling method. The prevalence of soil-transmitted helminth and taenia infections was surveyed in all sites. The prevalence of intestinal protozoa infections was surveyed only in 10 village sites. In each survey site, no less than 250 permanent residents with age above 3 years old were recruited. Fecal sample was collected from each participant and the eggs of intestinal helminthes were examined in duplicate under microscope using Kato-Katz technique. Tube filter paper culture method was applied to culture the larvae and identify the species of hookworm. The Enterobius eggs were detected in children aged 3 to 6 years old by using adhesive tape. The cysts and trophozoites of intestinal protozoans were examined using saline direct smear and iodine staining. SPSS 21.0 software was used for statistical analysis. Results A total of 4 773 individuals were surveyed for HIPD from 18 selected sites with an overall infection rate of 13.3%(633/4 773) for HIPD infections. The prevalence of intestinal protozoa infections was 2.8%(76/2 698) with 5 species of protozoans identified. The prevalence of helminth infection was 12.1%(576/4 773) with7 species of helminths including whipworm(5.6%) and hookworm(4.3%) as main species. Using adhesive tape method, 252 children of 3-6 years old were examined for the infection of E. vermicularis, and an infection rate of31.4%(79/252) was found among the children examined. No Taenia infection was found. A total of 143 fecal samples with hookworm egg positive were cultured for identifying the species of hookworm, 120 of them were Necator ameicanus only, while other 23 were mixed with N. am
