【摘要】：目的了解安徽省27个血吸虫病疫情控制县(市、区)疫情现状。方法按照《血吸虫病防治地区达标考核评估方案》确定的抽样调查方法,在安徽省27个血吸虫病疫情控制县(市、区)各抽取3个疫情相对较重的乡(镇),每个乡(镇)抽取1个疫情相对较重的流行村作为调查现场。调查常住人口和散养家畜病情,以及近3年查出钉螺且人畜活动频繁环境的钉螺感染情况。同时,查阅各县(市、区)近年来感染性钉螺调查结果和当地感染急性血吸虫病疫情资料。结果现场共抽查81个乡(镇)81个村。累计血清学检查34 293人,阳性1 086人,平均阳性率为3.17%(0.65%~9.58%);累计粪检1 068人,平均阳性率为0.37%(0~4.0%),推算人群平均感染率为0.01%。累计调查家畜3 057头(只),其中牛438头,羊2 550只,其他家畜69只,均未查到阳性。累计调查钉螺60 944框,捕获活螺11 261只,解剖全部活螺均未发现感染性钉螺。27个县(市、区)均在调查前2年以上未查出感染性钉螺,平均未查出感染性钉螺年限为2.9年(2~6年);均已2年以上未发生急性血吸虫病,平均未发生急性血吸虫病年限为4.9年(2~9年)。结论安徽省血吸虫病疫情控制地区人畜病情较低,已查不出感染性钉螺。
[Abstract]:Objective to understand the epidemic situation of schistosomiasis in 27 counties (cities and districts) in Anhui province. Methods according to the method of sampling investigation, 27 counties (cities) of schistosomiasis control in Anhui province were selected. Each of the three townships (towns) with relatively heavy epidemic situation and one epidemic village with a relatively heavy epidemic situation were selected as investigation sites in each township (town). To investigate the condition of resident population and scattered livestock, and to find out the snail infection of snail in the last three years in the environment of frequent human and animal activities. At the same time, the survey results of infected snails in various counties (cities and districts) in recent years and the epidemic data of local acute schistosomiasis infection were consulted. Results A total of 81 villages were investigated. The average positive rate was 3.17% (0.659.58%), and the average positive rate was 0.37% (04.0%) for 1 068 stool samples. The average infection rate was 0.01%. A total of 3 057 domestic animals were investigated, of which 438 were cattle, 2 550 sheep and 69 other domestic animals. A total of 60,944 frames of snails were investigated, 11 261 live snails were captured, and no infected snails were found in all the living snails dissected. All the 27 counties (cities and districts) did not find infected snails more than 2 years before the investigation. The average number of years of undetected infected snails was 2.9 years (2 ~ 6 years), and no acute schistosomiasis occurred for more than 2 years, and the average number of years without acute schistosomiasis was 4.9 years (2 ~ 9 years). Conclusion the infection of infected snails was not detected in the area of schistosomiasis control in Anhui province.
