目的了解云南省高原山区血吸虫病流行区居民野外自由放牧和野外大便(野便)行为情况。方法选择鹤庆县西甸、磨光2个行政村作为研究试区。随机抽取30%的6~65岁居民,以询问式问卷调查的形式,调查其野外自由放牧和野便的行为情况,并对调查对象进行血清学检查,了解其血吸虫病感染情况。结果共调查居民412人。居民对家畜饲养回答圈养、自由放牧、不知道和没有回答的人数所占的比例分别为55.34%、4.85%、26.94%和12.86%。居民无放牧行为、每周放牧<5次、每周放牧≥5次人数占调查人数的比例分别为75.49%、16.02%和8.50%。居民无野便行为、每周野便<5次、每周野便≥5次和没有回答的人数占调查人数的比例分别为68.45%、27.67%、2.91%和0.97%。结论鹤庆县血吸虫病流行区居民野外自由放牧和野便行为较普遍,对当地血吸虫病防治工作影响较大,在今后的防治工作中仍应突出人畜粪便管理和禁牧措施,巩固血吸虫病防治成果,以实现传播阻断目标。
Objective To understand the behavior of free grazing and field stool (wild stool) behavior in the endemic areas of schistosomiasis endemic areas in Yunnan plateau mountainous areas. Methods Heidian County Xidian, polished two administrative villages as the study area. Thirty percent of residents aged from 6 to 65 were randomly selected to investigate the behavior of free grazing and wild stool in the form of questioning questionnaire. Serological tests were conducted on the subjects to find out the status of schistosomiasis infection. Results A total of 412 residents were surveyed.

Residents had no wild activities, <5 visits per week,> 5 visits per week and 68.45%, 27.67%, 2.91% and 0.97% of the respondents, respectively. Conclusion Residents in the endemic areas of Heqing schistosomiasis endemic to the area are more likely to have free grazing and wild fecundity, which has a great impact on the prevention and control of schistosomiasis. In the future prevention and control work, manure and livestock grazing management and banned animal husbandry should be emphasized to strengthen the prevention and control of schistosomiasis Achievements in order to achieve the goal of blocking transmission.
