To evaluate the implementation of Survey of oncomelanid snails (WS/T 563-2017) in schistosomiasis-endemic foci, two schistosomiasis-endemic counties were selected from two provinces of Sichuan and Anhui. Professional staff working in province-, city-, county- and township-level disease control and prevention institutions, parasitic disease control institutions or medical institutions were recruited, and the understanding, use and implementation of Survey of oncomelanid snails (WS/T 563-2017) were investigated using questionnaires and interviews. The awareness, use, proportion of propagation and implementation and correct rate of answering questions pertaining to Survey of oncomelanid snails (WS/T 563-2017) were analyzed. A total of 270 questionnaires were allocated, and 269 were recovered, including 254 valid questionnaires. The overall awareness of Survey of oncomelanid snails (WS/T 563-2017) was 84.64% (215/254), and propagation and implementation of Survey of oncomelanid snails (WS/T 563-2017) was not performed in 23.28% (17/73) of the survey institutions following implementation of Survey of oncomelanid snails (WS/T 563-2017), with meeting training and allocation of propagation materials as the main type of propagation and implementation. Among 254 respondents, 77.16% (196/254) were familiar with the standard, 66.14% (168/254) understood the conditions for use of the standard during snail surveys, and 96.85% (246/254) had the approach for identifying snails. In addition, there were 41.73% (106/254), 50.78% (129/254) and 7.48% (19/254) of respondents that considered the operability of Survey of oncomelanid snails (WS/T 563-2017) was very good, good and general, respectively. The findings demonstrate that the issue and implementation of Survey of oncomelanid snails (WS/T 563-2017) has filled the gap for the standardization of snail control techniques, and which plays an importang guiding role in the national schistosomiasis control program.
［摘要］ 为了解《钉螺调查》 (WS/T 563—2017) 在血吸虫病流行区实施情况, 选取四川省和安徽省流行县作为调查现场, 分层选取省、市、县 (区) 及乡 (镇) 四级疾病预防控制中心或寄生虫病防治所、医疗机构的专业技术人员作为调查对象, 采 用问卷调查与访谈相结合的方式对《钉螺调查》 (WS/T 563—2017) 知晓率、使用率、培训宣贯率、答题正确率等进行调查。累计发放问卷270份, 回收269份, 有效问卷254份。《钉螺调查》 (WS/T 563—2017) 知晓率达84.64% (215/254); 在《钉螺 调查》 (WS/T 563—2017) 实施后, 有23.28% (17/73) 的单位未进行过宣贯, 主要的宣贯方式包括会议培训和发放宣传资 料。254名调查对象中, 有77.16% (196/254) 熟悉该标准, 66.14% (168/254) 在钉螺调查过程中清楚各项调查法使用场景, 96.85% (246/254) 掌握钉螺鉴别方法。认为《钉螺调查》 (WS/T 563—2017) 操作性很好、较好、一般的调查对象人数比例 分别为41.73% (106/254)、50.78% (129/254) 和7.48% (19/254)。结果表明, 《钉螺调查》 (WS/T 563—2017) 的颁布及实施 填补了行业内对钉螺控制技术标准化的空白, 在血吸虫病防治中发挥了重要的规范作用。.
