目的分析2014年银川市麻疹发病情况,了解健康人群麻疹抗体水平,以便为制定麻疹免疫策略提供科学依据。方法对法定传染病报告系统和麻疹监测系统疫情资料以及分层随机抽查银川市健康人群724名的麻疹IgG抗体水平检测结果进行描述性统计分析。结果 2014年全市共报告麻疹疑似病例112例,实验室确诊麻疹病例56例,麻疹年发病率为2.65/10万;健康人群麻疹抗体阳性率为91.71%,不同地区、不同年龄组人群麻疹IgG抗体阳性率差异有统计学意义(P<0.05)。结论银川市麻疹防控效果和健康人群麻疹抗体阳性率较好,但仍应对一些重点地区、重点人群加强管理,定期进行抗体水平监测,适时开展查漏补种和强化免疫,必要时建议扩大强化免疫年龄组。
Objective To analyze the incidence of measles in Yinchuan in 2014 so as to understand the level of measles antibody in healthy population so as to provide a scientific basis for formulating measles immunization strategy. Methods Descriptive statistical analysis of the epidemiological data of legal infectious disease reporting system and measles monitoring system, as well as the level of measles IgG antibody in 724 healthy people from stratified random sampling were conducted. Results In 2014, 112 suspected measles cases, 56 measles cases were confirmed in laboratory and the annual incidence of measles was 2.65 per 100 000. The positive rate of measles antibody in healthy population was 91.71%. The measles IgG antibody in different regions and different age groups The positive rate difference was statistically significant (P <0.05). Conclusion The measles control and measles antibody positive rate in healthy population is good in Yinchuan. However, we should strengthen the management of some key areas and key population, monitor the antibody level regularly, carry out leak detection, seed dressing and immunization, and if necessary, Immune age group.
