Surveillance of varicella in Ningbo, Zhejiang, 2011

  • 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(P0.001),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。

     

    Abstract: Objective understand the epidemiological characteristics of varicella in Ningbo in 2011 and provide scientific evidence for the prevention and control of varicella. Methods The surveillance of varicella was conducted in Ningbo in 2011 and descriptive epidemiological analysis was performed on the surveillance data. Results A total of 2797 varicella cases were reported in 2011 and the incidence rate was 73.19/lakh. The incidence was highest in Yuyao (117.62/lakh) and lowest in Yinzhou(44.34/lakh). The incidence peaks were during May-June and during November-January. The cases mainly occurred in children aged12 years and the age distribution of the cases varied with area. The average varicella vaccination rate was 73.01% among children aged 1-7 years and varied with age group and area. There was a negative correlation between the incidence of varicella and the rate of vaccination. Conclusion The incidence of varicella was high in Ningbo in 2011 and the vaccination rate of varicella varied with area and age group. It is important to strengthen varicella vaccination in children aged 1-2 years and students for the prevention and control of varicella.
