目的了解影响荆州市血吸虫病传播控制达标的风险因素,为快速处置风险提供科学依据。方法全市6个县(市、区)各抽查1个村,每村调查3个环境。以村为单位,现场抽样调查钉螺和野粪分布情况,并进行风险分级评估。结果现场抽查活螺平均密度为0.43只/0.1 m2,有螺框出现率为9.12%,未发现感染性钉螺。现场野粪均为牛粪,环境点野粪阳性率为37.50%(3/8),牛粪阳性率为8.11%(3/37)。居民点附近野粪阳性率为0,沟渠和堤坡野粪阳性率分别为12.50%和8.33%,差异无统计学意义(χ2=0.07,P>0.05)。结论牛仍是荆州市主要血吸虫病传染源,是影响传播控制达标的主要风险因素,需加大对牛的控制力度。
Objective To understand the risk factors that affect the transmission control of schistosomiasis in Jingzhou City and provide a scientific basis for rapid treatment of the disease. Methods Six sampling counties (cities and districts) in the city were randomly selected for testing one village and three villages for each village. The village as a unit, on-site sampling survey snails and wild feces distribution, and risk rating assessment. Results The average spot density of live snails was 0.43 /0.1 m2. The incidence rate of snails was 9.12%. No infectious snails were found. The field manure was cow manure, the environmental point of the positive rate of stool was 37.50% (3/8), cow dung positive rate was 8.11% (3/37). The positive rate of stool near settlements was 0, and the positive rates of stool and dykes were 12.50% and 8.33%, respectively, with no significant difference (χ2 = 0.07, P> 0.05). Conclusion Cattle is still the main source of schistosomiasis infection in Jingzhou City, which is the main risk factor affecting the transmission control standard. It is necessary to increase the control of cattle.
