目的 目的 了解上海市金山区外来务工人员的血吸虫感染及预防知识知晓情况， 为传播阻断地区开展外来务工人员 防治工作提供科学依据。方法 方法 对来自血吸虫病流行省份的外来务工人员和当地居民采用间接血凝法 （IHA） 筛查， 血检 阳性者采用改良加藤法和孵化法联合查病， 问卷调查血吸虫病知晓和行为情况。结果 结果 共调查579人， 其中来自流行省份 的外来务工人员348人， 本地居民231人， 男性占72.0%， 女性占28.0%。外来务工人员以来自安徽省的最多， 占36.2%， 年 龄上以20 ~ 29岁最多， 占56.0%， 受教育程度高中及以上占56.6%。在外来务工人员中查出血清学阳性4人， 阳性率为 1.15%； 查出粪检阳性1人， 推算血吸虫感染率为0.29%， 当地居民未查到血清学阳性者和病人。外来务工人员在户籍地愿 接受血吸虫病检查和治疗的占79.9%， 在务工地愿接受血吸虫病检查和治疗的占84.8%， 在务工地自费检查和治疗血吸虫 病的占48.6%。外来务工人员的血吸虫病知识知晓情况普遍较差， 部分人员存在就诊和服药的不正确行为。结论 结论 来自 流行省份的外来务工人员中存在血吸虫感染者， 其血吸虫病预防知识知晓程度较低， 增加了当地血吸虫病传播风险。

Investigation on schistosomiasis japonica infection and preventive knowledge of immigration population in Jinshan District,Shanghai

Objective To investigate the schistosomiasis japonica infection and preventive knowledge of immigration popula-tion in Jinshan District,Shanghai so as to provide the evidence for improving the control work. Methods The immigration popula-tion from schistosomiasis endemic provinces and local people were screened by serum IHA screening for schistosome infection, and the positives were further examined by Kato-Katz technique and the miracidium hatching method. The schistosomiasis preven-tive knowledge and behaviors were investigated by questionnaires. Results A total of 579 were investigated with 348 immigration people and 231 local people,and among them,the male accounted for 72.0%and female accounted for 28.0%. In the immigration population,the main age group was 20-29（56.0%）,and 56.6%of the immigration had an education level at senior middle school or higher. The most proportion of immigration was from Anhui Province（36.2%）. There were 4 IHA positive persons（1.15%）in the immigration,and 1 was positive in the stool test,and the schistosome infection rate was 0.29%. There were no positives in the local people. The schistosomiasis preventive knowledge of the immigration was generally poor,and some people’s behaviors of see doctor and medication were incorrect. Conclusion There are schistosome infected persons among the immigration population from schistosomiasis endemic provinces,and their schistosomiasis prevention knowledge was poor,thus there is a schistosomiasistransmission risk.
