摘要
目的分析苏州市相城区2010-2020年水痘报告病例流行病学特征,为辖区制定更切合现况的水痘免疫预防策略提供依据。方法苏州市相城区水痘报告病例来源于中国疾病预防控制信息系统(现住址为相城区,报告发病日期为2010-2020年),采用描述性流行病学方法对水痘报告病例和水痘疫苗接种资料进行统计分析。结果苏州市相城区2010-2020年共报告水痘病例8005例,年均报告发病率为101.13/10万,各年均报告发病率为4.19/10万(2010年)~377.23/10万(2019年),差异有统计学意义,χ^(2)=249.84,P<0.01。发病高峰为每年的10月份至次年的1月份,及每年的5~7月份。各地区年均报告发病率比较,差异有统计学意义,χ^(2)=62.20,P<0.01。6~10岁年龄组年均报告发病率居首,为1692.06/10万;1~5岁年龄组年均报告发病率次之,为728.80/10万;各年龄组年均报告发病率比较,差异有统计学意义,χ^(2)=59222,P<0.01。共报告1~7岁水痘病例3942例,其中有疫苗免疫史1359例,占34.47%;接种疫苗至发病间隔时间为(47.03±20.94)个月。结论相城区水痘报告发病率处于较高水平,以幼托儿童和学生为主。除持续加强水痘疫苗2剂次接种外,还需加强高发场所和高发人群的宣教。
Objective The epidemiological characteristics of varicella in Xiangcheng district during 2010-2020 were analyzed to provide bases for making better prevention strategies.Methods We collected varicella cases in the chinese disease prevention and control information system form 2010 to 2020 for a descriptive epidemiological analysis.Results A total of 8005 varicella cases were reported in Xiangcheng during 2010-2020 for an average annual incidence of 101.13 per 100000 population,the incidence ranged from 4.19 per 100000 in 2010 to 377.23 per 100000 in 2019,the difference in average annual incidence among different years was statistically significantχ^(2)=249.84,P<0.01.Peak seasons for varicella cases were October to next year January and May to July of each year.The difference in average annual incidence among different areas was statistically significantχ^(2)=62.20,P<0.01.The average incidence rate of 6-10 years old group was the highest,accounting for 1692.06/10 million.The average annual incidence rate of 1-5 age group was 728.80/10 million.The incidence rate of age reported in each age group was statistically significant,χ^(2)=59222,P<0.01.A total of 3942 varicella cases aged 1-7 years were reported,of which 1359 cases(34.47%)had vaccination history.The interval between vaccination and onset was(47.03±20.94)months.Conclusions The reported incidence of varicella cases in Xiangcheng District was at a high level,mainly among students and children in preschool care.In addition to strengthening the two doses of varicella vaccine,it is also necessary to strengthen the high incidence of places and high incidence of population publicity.
