【摘要】 目的了解皖南山区学生并殖吸虫感染现状及其易感因素。方法采用随机整群抽样的方法,采集黄山市936名小学生末梢血,利用酶联免疫吸附试验(ELISA)法检测血清中并殖吸虫特异抗体IgM和IgG,以确定其感染情况;同时进行《并殖吸虫易感因素》的问卷调查,分析其感染的危险因素。结果并殖吸虫总感染率为12.07%(113/936),各县区感染率的差异具有统计学意义(P<0.05);单因素分析结果显示,在不同性别、是否食用溪蟹、饮用水源不同、是否喝生水及对并殖吸虫知识不同知晓情况的调查对象中,其感染率的差异具有统计学意义(P<0.05)。结论黄山市小学生并殖吸虫感染率较高,该地区仍是并殖吸虫流行的疫源地。男性、食用溪蟹及不了解并殖吸虫预防知识的人群更易感染并殖吸虫,应作为重点防治对象。更多还原

【Abstract】 Objective To investigate the Pamgonimus infection status and predisposing factors to this species in primary school students living in the mountain areas of southern Anhui province.Methods By random cluster sampling method,we conducted a survey on 936 students in Huangshan City by obtaining the peripheral blood samples which were determined for the Paragonimus specific antibodies(IgM and IgG) by ELISA to examine the infection status.Besides,self-programmed questionnaire on the susceptibility to Paragonimus infection was performed to analyze risk factors.Results The overall infection rate with Paragonimus was12.07%(113/936),and varied significantly in students from different areas(P<0.05).Single factor analysis showed that the infection rate was dissimilar in different genders,and students with or without history of ingestion of crabs,intake of unboiled water or drinking water from different sources,as well as knowledge and awareness of Paragonimus infection(P<0.05).Conclusion Higher infection rate with Paragonimus was found in the elementary school students living in Huangshan City,suggesting that this area remains endemic focus of this species.And prevention should be weighed on the male students,and those with habit of eating crabs and poor knowledge on Paragonimus infection,since they are susceptible population.更多还原
