目的：探讨某学校1起感染性腹泻爆发疫情的流行特征，为制定防治对策提供依据。方法按照病例定义开展病例搜索，采用描述性流行病学方法进行分析，并随机选择未发病学生进行病例对照研究，对调查对象的病例接触史、饮水、就餐等情况进行调查，分析可能的暴露因素。采集部分病例的肛拭子及直饮水、自来水等水样进行诺瓦克病毒核酸检测。结果2013年4月11日至4月15日，该学校共发生病例74例，罹患率3.36％(74/2200)，病例均为该校学生，其中男生罹患率4.2％(42/1000)，女生罹患率2.7％(32/1200)，男生高于女生(Ρ＜0.05)。病例对照研究提示，发病与直饮水暴露存在较强相关联( O R＝5.18,95％C I为2.65-10.18)。共检测10份病人肛拭子、13份水样，其中8份肛拭子样本和3份水样(第一和第二食堂末梢水样各1份、教学楼2楼直饮水样1份)中检测到诺瓦克病毒核酸。结论该起疫情为水源性诺瓦克病毒感染性腹泻爆发疫情。建议加强企业自供水管网的监督检查，规范校园直饮水卫生管理。

Objective Discussion on the epidemic characteristics of infectious diarrhea in a school of 1 outbreaks, and to provide basis for prevention. Methods According to the case definition for case search, using descriptive epidemiological analysis method, and random selection is not the sick students conducted case-control study, investigating the case contact history, drinking, eating and so on, analyze the possible exposure factors. Part of the col ection of cases of rectal swab and direct drinking water, tap water samples were Novak virus nucleic acid detection. Results From April 11, 2013 to October 15th, the school a total of 74 cases, the attack rate was 3.36% (74 / 2200), were the students in this school, the boys attack rate was 4.2% (42 / 1000), female 2.7% (32 / 1200), boys than in girls (P < 0.05). Case control study tips, and the incidence of direct drinking water exposure there is strong associated (OR = 5.18,95%CI = 2.65-10.18). A total of 10 test samples were anal swab, 13 water samples, including 8 patients with anal swab samples and 3 water samples (the first and second terminals, water canteen 1 copies each building 2 building direct drinking water 1) detected in the Novak virus nucleic acid. Conclusion The outbreak of diarrhea outbreaks of waterborne Novak virus infection. Suggestions to strengthen enterprise supervision and inspection from the water supply pipe network, standardizing campus drinking water hygiene management.
