摘要
分析江西省钩虫感染流行变化趋势和现状,为制定防治对策提供依据.收集并分析1989、2002和2015年3次全国人体寄生虫病抽样调查(以下简称寄调)中江西省钩虫病的调查数据以及2016-2020年江西省土源性线虫病国家监测点中钩虫感染的监测数据.采用改良加藤厚涂片法检查钩虫感染情况;采用试管滤纸培养法进行钩蚴培养,鉴定钩虫虫种.3次寄调结果显示,1989、2002和2015年江西省人群钩虫感染率分别为17.63％(9 176/52 042)、7.39％(1 490/20 154)和 4.63％(1 094/23 606),呈下降趋势(x2=3 112.64,P＜0.05).1989 和2015 年女性感染率(18.68％和 5.59％)均高于男性(16.60％和 3.88％)(x2=38.71、28.85,均 P＜0.05).1989 年50～59岁年龄组人群的感染率最高(27.33％),2002和2015年≥ 60岁年龄组最高(12.37％和10.06％).1989年江西省钩虫感染的优势虫种为十二指肠钩虫、2002和2015年为美洲钩虫.2016-2020年,江西省人群各年度钩虫感染率分别为 1.04％(116/11 126)、1.09％(122/11 203)、0.63％(70/11 183)、1.00％(112/11 197)和0.62％(70/11 240),呈下降趋势(x2=44.85,P＜0.01);在性别分布上,女性钩虫感染率(0.97％,269/27 718)高于男性(0.78％,221/28 231)(x2=5.98,P＜0.05);在年龄分布上,≥ 60岁年龄组居民感染率最高(1.51％,235/15 594).江西省人群钩虫感染率呈现持续下降态势,并维持低度流行状态,但部分地区钩虫感染率依然较高.女性和高年龄组人群是目前钩虫病防治工作的重点人群.
Abstract
To analyze the epidemic trend and current situation of hookworm disease in Jiangxi Province,all for providing a basis for formulating countermeasures of hookworm disease.The survey data of hookworm disease in Ji-angxi Province in three national sampling surveys of human parasitic diseases(1989,2002 and 2015)and the surveil-lance data of hookworm infection in the national monitoring sites of soil nematode disease in Jiangxi Province from 2016 to 2020 were analyzed,respectively.The Kato-katz smear method was used in the survey and surveillance to ex-amine the hookworm infection,and the test-tube filter paper culture method was used to identify hookworm species.The results showed that the infection rate of hookworm in Jiangxi were 17.63％(9 176/52 042)in 1989,7.39％(1 490/20 154)in 2002 and 4.63％(1 094/23 606)in 2015 with the downtrend as a whole(x2=3 112.64,P＜0.05).The in-fection rates in female in 1989 and 2015(18.68％and 5.59％)were higher than that in male(16.60％and 3.88％)(x2=38.71,28.85,both P＜0.05).As for the age distribution of infection in 3 national surveys,the infection rate in age group of 50-59 in 1989 was the highest(27.33％),and the rates in ≥ 60 age group in 2002 and 2015 were the highest accordingly(12.37％and 10.06％).The dominant species of hookworm in 1989 was Ancylostoma duodenale,while Necator americanus becoming dominant in 2002 and 2015.The infection rates of hookworm from 2016 to 2020 in Jiangxi were 1.04％(116/11 126),1.09％(122/11 203),0.63％(70/11 183),1.00％(112/11 197)and 0.62％(70/11 240),respectively and continued to decline(x2=44.85,P＜0.01).In the gender distribution,the infection rate of female(0.97％,269/27 718)was still higher that of male(0.78％,221/28 231)(x2=5.98,P＜0.05).In the age distribution,the infection rate in ≥ 60 age group was still the highest(1.51％,235/15 594).The analysis results indicated that the infection rate of hookworm shows a continuous decline trend,and maintains a low epidemic state in Jiangxi.Rural women and high age groups are the focus of hookworm control.
