Abstract: Objective To understand the status of water contact and labor practice of residents in plateau mountain schistosomiasis endemic areas in Yunnan Province, so as to provide the evidence for formulating the strategy of prevention and control of schistosomiasis in the next step of work. Methods A total of 412 residents aged 6-65 years old in 2 villages were randomly sampled and investigated with questionnaires for their water contacts and labor practices in plateau valley schistosomiasis endemic areas. Then the schistosome infection status of the residents was surveyed with the indirect hemagglutination assay (IHA). Results Among the 412 residents investigated, the rate of water contact was 88.35%, and the main causes of water contact were watering, and swimming and playing. The percentages of residents who had schistosomiasis history were 1.16%, 0.00%, 30.80%, 3.85%, and 0 in them who had swimming and playing water?contacts, bathing, watering, washing hands, and others, respectively ([χ2]= 38.96, P < 0.01). The positives of IHA in the above?mentioned residents were 18.60%, 0.00%, 37.60%, 23.08%, and 0, respectively ([χ2]= 12.61, P < 0.05). Conclusions The productive infested water contact is the main way of schistosome infection. Therefore, the changes of labor practices and water contact of the residents are very important for the effective prevention and control of schistosomiasis transmission.

摘要: 目的 了解和掌握云南高原山区血吸虫病流行区居民接触水体和参加劳动情况,为制定防治措施提供科学依据。方法 选择鹤庆县金墩乡高原峡谷型血吸虫病流行区西甸和磨光2个行政村作为调查试区,对6 ~ 65岁居民采用随机抽样的方法开展问卷调查,了解居民是否接触水体、接触水体原因、参加劳动情况。问卷后,对调查对象采用间接血凝试验(IHA)进行检查,了解其血吸虫感染情况。结果 接触过水体和没有接触过水体的人数占调查总人数的比例分别为88.35%和11.65%,灌溉和游泳玩耍是居民接触水体的主要原因。因游泳玩耍、洗澡、灌溉、洗手和其它原因接触水体的居民中有血吸虫病病史的人数比例分别为1.16%、0、30.80%、3.85%、0,差异有统计学意义([χ2]= 38.96,P < 0.01);因上述原因接触水体的居民中本次IHA阳性的居民比例分别为18.60%、0、37.60%、23.08%、0,差异有统计学意义([χ2] = 12.61,P < 0.05)。居民中没有参加劳动、每周劳动< 5次、每周劳动≥ 5次、没有回答人数占调查人数的比例分别为39.81%、16.50%、43.20%、0.49%,有血吸虫病病史的人数比例分别为13.41%、19.12%、31.46%、0,差异有统计学意义([χ2]= 17.17,P < 0.01);IHA阳性的人数比例分别为19.51%、38.24%、35.96%、50.00%,差异亦有统计学意义([χ2]= 14.21,P < 0.01)。结论 生产性劳动是血吸虫病感染的主要途径,改变人们的接触水体行为和劳动方式对有效控制血吸虫病的流行和传播有重要意义。
