Abstract: 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，采用问卷填写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。
