摘要
目的:分析青岛市市北区水痘流行特征,为水痘防控和制定免疫策略提供科学依据。方法:通过中国疾病预防控制信息系统收集2013—2021年青岛市市北区水痘报告病例数据,采用描述性流行病学方法对病例进行“三间”分布和发病率分析。结果:2013—2021年市北区共报告水痘病例6711例,年均发病率为68.87/10万。2013—2021年水痘发病率由94.60/10万下降至42.66/10万,不同年份间水痘发病率的差异有统计学意义(χ^(2)=1123647.38,P<0.01)。水痘发病呈现明显季节性,每年3—5月和11月—次年1月为水痘高发期。男性3489例,女性3222例,男女性别比例为1∶0.92。发病人数排前3位的年龄组分别为15~19岁、5~9岁、10~14岁,3个年龄组发病人数占总病例数的47.77%,水痘发病年龄出现后移现象。职业分布以学生为主,发病人数占总病例数的44.23%。结论:2013—2021年市北区水痘发病率明显下降,发病年龄后移,以学生为主。水痘防控应重点关注中小学生,加强综合防控措施,加强水痘疫苗接种的宣传和入学查验,提高水痘疫苗接种率。
