2004年肠道门诊期间其他感染性腹泻病原学监测

目的 探索引起儿童其他感染性腹泻的主要病原体的流行病学特征，提出相应的防制方法。方法 选取医院网络直报的其他感染性腹泻实验室诊断病例，比较各种病原体在地区、性别、年龄之间所占构成比的差异，以及流行的季节性。结果 引起儿童其他感染性腹泻的主要病原体是轮状病毒和空肠弯曲菌，构成比分别是30．89％、69．02％;两者的感染构成比无地区、性别的差异，年龄方面其中轮状病毒6个月～2岁易感，而空肠弯曲菌6个月以内易感；季节方面轮状病毒入秋后流行，空肠弯曲菌春夏季流行。结论 降低儿童其他感染性腹泻主要防制轮状病毒和空肠弯曲菌，研制高效安全的疫苗。

Surveillance on Pathogenic Etiologic Factors of Infectious Diarrheal Other Than Cholera at Enteric Clinic in 2004

Objective To explore the epiderniological trait of the major pathogenic etiologic factors other than cholera caused infectious diarrhea among children. Methods Infectious diarrhea children other than cholera were diagnosed, selected and reported through network, and the difference of area, sex, age and epidemic seasonal composition of various etiologic fators were evaluated. Results The leading pathogens were Rotavirus and Campylobacter jejuni, and the constitution ratio were 30.89% and 69.02% respectively. No area and sex difference was found, but rotavirus tended to ihfecting young children between 6 months and 2 years old, Campylobacter jejuni tended to infecting baby within 6 months. Rotavirus prevailed easily in autumn, when entered into spring and summer, Campylobacter jejuni infection became deminant. Conclusion Major other infections diarrhea diseases among young children are mainly Rotavirus and Campylobacter jejuni infections, which are the target of prevention; and the development of high-effect and safe vaccine is warranted to reduce their incidences.
