摘要
目的掌握三峡库区影响血吸虫病流行的相关因素,为制定预防控制方案提供依据。方法设立监测点,建立病例报告制度,开展个案调查;对人群采用间接血凝试验(IHA)作血清抗体筛查,阳性者进行粪便检查;调查家畜和植物引进情况等。结果分别检查从疫区返乡人员、来渝人员88、107人,血清抗体阳性率分别为1.14%、1.87%,未检出血吸虫卵;未发现从流行区引进的植物和家畜;当地居民生产以牛耕为主,经常接触江、河水。结论三峡库区存在血吸虫病传染源输入,存在血吸虫病流行的潜在威胁。
Objective To understand the correlative factors of impacting schistosomiasis prevalence so as to provide the scientific evidence for drawing up the control project in Three Gorges Reservoir areas. Methods The report system of schistosomiasis was set up, and the cases were investigated. The population were screened by indirect haemagglutination test (IHA), and the serum-positive people were examined with Kato-Katz technique. The livestock and plants imported from the schistosomiasis endemic areas were investigated. Results Eighty-eight floating people returning from schistosomiasis endemic areas and 107 floating persons from endemic areas were investigated, and the serurn positive rates were 1.14% and 1. 87%, respectively. No schistosome eggs were found in stool examinations. There was no livestock and plant imported from schistosomiasis endemic areas. The production of local inhabitants depended on mainly eatde, and the river water contact was popular. Conclusions There are infection resources of schistosomiasis imported from endemic areas, which has a potential risk of schistosomiasis prevalence.
