摘要
目的分析2011年宁波市水痘疫情流行病学特征,为开展预防控制工作提供参考依据。方法 2011年在宁波市建立水痘监测点,监测水痘病例,并调查病例的个案信息及监测点水痘疫苗接种率的相关信息,采用描述性流行病学方法进行分析。结果 2011年1-12月水痘监测点共监测水痘病例2797例,发病率为73.19/10万。其中,余姚市发病率最高,为117.62/10万,鄞州区发病率最低,为44.34/10万。每年5-6月以及11月至次年1月发病数较多,发病以<12岁儿童为主,不同地区年龄分布存在差异。1～7岁水痘疫苗平均接种率为73.01%,各地、各年龄组接种率不完全相同(P<0.001),接种率与发病率呈负相关。结论宁波市水痘发病率较高,水痘疫苗接种率存在地区、年龄差异,今后应继续加强适龄儿童和高年龄组儿童的水痘疫苗接种工作,将水痘疫情控制在较低水平。
