摘　　要：目的了解福建省人体钩虫感染的流行现状,为巩固钩虫病防治成果和控制钩虫感染率提供依据。方法于2015年按《全国人体重点寄生虫病现状调查方案》要求,采用分层整群随机抽样法抽取福建省农村常住人口,采集粪便标本,用改良Kato-Katz涂片法和试管滤纸培养法检查钩虫卵;对钩虫感染率、感染度、地区、人群分布和虫种构成进行描述性分析。结果共调查10 652人,检出钩虫感染358例,感染率为3.36%;以轻度感染为主,占81.56%。调查的15个县(市、区)仅周宁县未检出钩虫感染,宁化县钩虫感染率最高,为15.73%。浙闽山地丘陵生态区的钩虫感染率平均为4.00%,高于滇桂粤中部闽南山地丘陵生态区的2.68%(P<0.05)。男、女性钩虫感染率分别为3.06%和3.65%,差异无统计学意义(P>0.05)。钩虫感染率随着年龄增长呈上升趋势(P<0.05),感染者平均(58.30±14.10)岁;农民钩虫感染率较高,为4.54%。虫种以美洲钩虫为主,检出率为59.86%。结论福建省人群钩虫感染率有所降低,但与全国其他省份比仍处于较高水平;低经济水平地区务农的老年人是钩虫感染的主要人群。Objective To understand the prevalence of human hookworm infection in Fujian Province,and to provide evidence for the consolidation of hookworm disease prevention and further reduce the infection rate of hookworm.Methods In 2015,according to the requirements of the“National Survey on the Status of Human Key Parasitic Diseases”,the stratified cluster random sampling method was used to select the resident population of rural areas in Fujian Province,and the fecal specimens were collected to examine hookworm eggs by modified Kato-Katz smear method and test tube-filter paper culture method.Hookworm infection rate,infection degree,region,population distribution and species composition were descriptively analyzed.Results A total of 10 652 people were investigated and 358 cases of hookworm infection were detected.The infection rate was 3.36%,which was mainly caused by mild infection,accounting for 81.56%.Among the 15 counties(cities,districts)surveyed,the hookworms were not found in Zhouning County.The highest infection rate of hookworms was found in Ninghua County(15.73%);the average infection rate of hookworms in the hilly ecological regions of Zhejiang and Fujian was 4.00%,which was higher than the 2.68%of the hilly ecological regions in the southern part of Fujian and the central parts of Yunnan,Guizhou and Guangdong(P<0.05).The hookworm infection rates of male and female were 3.06%and 3.65%,respectively,and the difference was not statistically significant(P>0.05).The infection rate of hookworm increased with age(P<0.05),and the average age of infected people was(58.30±14.10)years old.The infection rate of hookworm was relatively high in farmers(4.54%).The detection rate of American hookworms was 59.86%.Conclusion The infection rate of hookworms in Fujian Province had decreased,but it was still remained at a relatively high level compared with other provinces in China;the elderly who were farmers in low-economic areas were the main population of hookworm infection.
