摘要
目的评估江苏省血吸虫病疫情控制的效果。方法采用回顾性分析与现场抽样调查相结合的方法,统计2004～2006年居民粪检阳性率、家畜粪检阳性率、急性血吸虫病发病人数、实有钉螺面积和感染性钉螺面积变化情况;2007年采用Kato-Katz法(1粪3检)和粪便毛蚴孵化法调查居民和家畜血吸虫感染情况,并现场抽查核对防治资料的准确性和完整性。结果2004～2006年全省居民血吸虫感染率分别为0.09%、0.07%、0.02%,家畜感染率分别为0.19%、0.06%、0.02%;发生急性血吸虫病人数分别为38、11、3例;钉螺面积分别为7882、5357、4067hm2;感染性钉螺面积分别为2131、1185、703hm2。2007年在12个县(市、区)共调查193个村,检查居民42227人,查出粪检阳性14人,人群平均感染率为0.03%。其中有10个村查到了粪检阳性病人,病人最多的村查出阳性3例,感染率为1.42%;调查各种家畜4292头(只),其中牛906头,羊3386只,未查到粪检阳性家畜;现场走访140户427人,其中送粪查病231人,查病登记结果和走访情况完全一致。结论2004年以来江苏省血吸虫病疫情逐年稳定下降,各项血吸虫病疫情指标已达到我国血吸虫病疫情控制标准的指标要求。
Objective To evaluate the effect of infection control of schistosomiasis in Jiangsu Province. Methods The retrospective analysis and field sample investigation were carried out to calculate and compare the schistosome positive rates of stool examinations in residents and livestock, the number of acute schistosomiasis patients, areas with Oncomelania snails and areas with infected Oncomelania snails in Jiangsu Province from 2004 to 2006 year by year. The schistosome infection rates in residents and livestock were surveyed with Kato-Katz technique （3 slides of 1 stool sample） and the hatching method in 2007. The accuracy and integrality of former field investigation data of schistosomiasis control were also evaluated with the field sample investigation in 2007. Results In Jiangsu Province, the infection rates of residents were 0.09%, 0. 07%and 0. 02%; the infection rates of livestock were 0.19%, 0.06% and 0.02%; the numbers of acute schistosomiasis patients were 38, 11 and 3; the areas with snail were 7 882, 5 357 hm^2 and 4 067 hm^2 ; and the areas with infected snail were 2 131, 1 185 hm^2 and 703 hm^2 from 2004 to 2006, respectively. In 2007, 42 227 residents were investigated in 193 villages of 12 counties （districts or cities）, 14 persons were schistosome positive in the stool examination and the average infection rate was 0.03% in the population. There were schistosomiasis patients （schistosome positive in the stool examinations） in 10 villages and there were 3 patients in one of the villages in which the infection rate was 1.42%. A total of 906 cattle and 3 386 sheep were investigated but the infection rate was zero. A total of 427 residents of 140 households were questioned, and among them, 231 persons said they once sent the stool samples for the examination, and the results were consistent with the record data before. Conclusions From 2004 to the present, the trend of endemic situation of schistosomiasis is decreasing year by year in Jiangsu Province. The indexes of infection control of schistosomiasis in Jiangsu Province have achieved the national criteria for infection control of schistosomiasis.
