2006-2012年贵州省风疹流行病学特征分析

Epidemiological Characteristics of Rubella in Guizhou Province

目的分析贵州省风疹流病学特征,为贵州省制定风疹控制措施和策略提供依据。方法对2006-2012年中国疾病监测信息报告管理系统报告的贵州省风疹发病数据进行描述流行病学分析。结果 2006-2009年贵州省风疹发病逐年上升,2010-2012年发病波动较大。2006-2012年均发病率为3.96/10万,每年4-7月为发病高峰。各市（州）均有病例报告,贵阳市年均发病率最高（15.41/10万）。5-9岁儿童风疹发病率最高（17.65/10万）。全省风疹病例实验室诊断率低,最高年份仅为32.90%。结论为防止风疹综合征的发生,今后应进一步加强风疹及风疹综合征的监测工作,探讨建立适合的风疹疫苗免疫策略。

Objective To analyze the epidemiological characteristics of rubella in Guizhou province,and provide evidence for formulating control strategies and measures.
