摘要：

目的：通过描述流行性腮腺炎暴发疫情的流行特征,寻找本次暴发的危险因素并提出有效的针对性防控措施。方法：搜索2012年9月1日以来该乡小学师生有腮腺或其他唾液腺肿胀者,以实验室确诊病例为病例组进行病例对照研究。结果：该小学发生流行性腮腺炎暴发,发病最多的是三年级2班和四年级2班,罹患率分别为41.67%和38.71%,有聚集现象。年龄主要集中在8、9岁组（占70%）,有年龄聚集现象。男∶女=1.63∶1, χ2=0.577,P=0.447,男女性别比差异无统计学意义。接种麻腮风联合疫苗是重要的保护因素（χ2=4.37 P=0.03 P＜0.05）,接种差异有统计学意义（OR=0.369 95%CI 0.14～0.94）。结论：此次疫情暴发是由于首发病例发现不及时,隔离期限不彻底所引起的,密切接触以及学校空间的相对密闭是此次疫情的危险因素,接种疫苗是控制流行性腮腺炎发病的重要保护因素。 ObjectiveTo describe the epidemic characteristics of the outbreak of mumps and find dangerous factors in this explosion,then make effective precautionary measures to prevent the occurrence of epidemic situation like this.

Some age-related assemblage phenomena were found. A ratio of boys and girls is 1.63:1 ,between which was no statistical significance(χ2=0.577, P=0.447). Inoculation MMR combined vaccine is an important protective factors,χ2=4.37 P=0.03(P＜0.05)and the difference has statistically significant(OR=0.369 95%CI 0.14～0.94). ConclusionThe outbreak is due to the initial cases that is not timely, the quarantine period is not completely cause,and the dangerous factors of this epidemic situation were close contact and inadequate indoor ventilation.
