目的通过对实验区感染病例家庭分布情况以及感染者亲属的感染情况的分析,探讨日本血吸虫病家庭聚集性以及家庭在血吸虫病传播中的作用。方法选择江西省九江市都昌县塘美行政村作为实验点,2002年对全村的1064人进行了病原学检查,并对其中的1015人进行了问卷调查和家庭人员调查。2003年对其中的两个高感染村418人进行追踪随访,12月份进行回顾性疫水接触调查。调查资料用ACCESS2002建立数据库,用SPSS做统计分析。结果江西塘美村血吸虫感染病例呈现家庭聚集性现象,感染者的亲属更易感染血吸虫病,血缘关系越近,发病机会越大。结论湖沼地区日本血吸虫病存在家庭聚集性,日本血吸虫感染不能排除受遗传因素影响。
Objective To investigate the family aggregation of schistosomiasis japonica and the role of the family in the transmission of schistosomiasis by analyzing the distribution of families infected in the experimental area and the infection of relatives of infected persons. Methods Tangmei Administrative Village, Duchang County, Jiujiang City, Jiangxi Province was selected as the experimental site. In 2002, 1064 people in the village were tested for the etiology, and 1015 of them were investigated by questionnaires and family members. In 2003, 418 high-infected villages among them were followed up, and a retrospective survey was conducted in December. Survey data using ACCESS2002 to establish a database, with SPSS statistical analysis. Results The cases of schistosomiasis infection in Tongmei Village in Jiangxi Province showed familial aggregation phenomenon. Relatives of infected persons were more likely to be infected with schistosomiasis. The closer the blood relationship, the greater the chance of onset. Conclusion There is familial aggregation of schistosomiasis japonica in lakes and mountains, and the infection of Schistosoma japonicum can not be ruled out by genetic factors.
