目的核实疫情,并探讨导致此次流行性腮腺炎爆发的危险因素,为今后的防治工作提出针对性的意见。方法按照现场流行病学的方法进行病例定义和病例搜索,并采用病例对照研究探讨疾病的危险因素。结果共搜索出119例病例,均为在校学生,罹患率为21%。5-6月共发生病例76例(64%),为发病高峰期。二年级罹患率最高(30%),一(3)班无1人患病。84%的患儿为流动儿童。以未发病班级学生作为对照进行logistic回归分析,结果表明,参加课外补习班和接触流行性腮腺炎患者是此次流行性腮腺炎爆发的主要危险因素,其OR值分别为3.7(95%CI:1.1-12.4)和60(95%CI:7-510.6)结论课外补习班和接触流行性腮腺炎患者是导致此次流行性腮腺炎爆发的主要危险因素,建议相关部门应对校外补习班加强监督,做好疾病宣传工作,加强补习班的环境卫生,经常通风,并对患病儿童进行隔离。

Results A total of 119 cases were searched, all of them were school-aged children, the attack rate was 21%. May-June a total of 76 cases (64%), the peak incidence. The second-year attack rate was the highest (30%), and one (3) shift was none. 84% of children with migrant children. The results of logistic regression analysis showed that participation in extra-curricular classes and mumps patients were the major risk factors for the outbreak of mumps with ORs of 3.7 (95% CI: 1.1-12.4) and 60 (95% CI: 7-510.6) Conclusions After-school remedial classes and patients with mumps are the main risk factors leading to the outbreak of mumps, the relevant departments should be recommended to strengthen supervision of extra-curricular remedial classes, Do a good job advocacy work to strengthen the cram school environmental health, regular ventilation, and isolation of sick children.
