目的研究医院暴露对麻疹发病的影响。方法采用病例交叉研究方法,通过专门设计的问卷对25例麻疹病例的监护人进行电话调查,选取2013年1-2月江门市所有报告的麻疹病例,对比发病前7~21 d(2周期间)和发病前37~51 d(2周期间)是否到过医院的发病情况。应用1∶3匹配的病例对照研究资料处理方法进行单因素分析。结果病例交叉研究显示,医院暴露为麻疹发病的危险因素(OR=7.11,95%CI:1.7~31.77);配比χ2检验结果显示,麻疹疫苗接种为控制疫情的保护因素(χ2=14.28,P<0.01)。结论避免医院暴露和按程序接种麻疹疫苗是预防麻疹的重要措施。
Objective To study the impact of hospital exposure on the incidence of measles. Methods A case-by-case cross-sectional study was conducted to investigate the cases of measles in 25 cases of measles from January to February in 2013 through a specially designed questionnaire. The incidence of measles in all cases was compared between 7 and 21 d (2 weeks) And before the onset of 37 ~ 51 d (2 weeks) have been to the hospital’s incidence. Application of 1: 3 matched case-control study data processing methods for univariate analysis. Results Cross-sectional studies showed that hospital exposure was a risk factor for measles (OR = 7.11, 95% CI: 1.7-31.77). The results of χ2 test showed that measles vaccination was the protective factor controlling the epidemic (χ2 = 14.28, P <0.01). Conclusion Avoiding hospital exposure and measles vaccination according to the procedure is an important measure to prevent measles.
