我们描述了1995年至2013年丹麦实验室确诊百日咳的发病率和年龄分布。自2007年以来,通知是强制性的。自1997年以来,使用了无细胞单组分疫苗。最近一次流行病发生在2002年,发病率为每10万人36人;自1995年以来,只有6名婴儿死亡。流行病之间的发病率低于十万分之十。1995年,确诊病例的平均年龄为9.2岁(95%置信区间(CI):7.9-10.5;中位数:5.1),2013年逐渐增加至23.9岁(95% CI:22.0-25.8;中位数:15.7)。1995年,14%的实验室确诊病例为20岁及以上,2013年为43%。在研究期间,发病率最高的是一岁以下儿童,在两次流行期间发病率为每100 000人84至331人(平均:每100 000人161人),2002年流行期间为435人。在2003年引入学龄前助推器后,一岁及以上儿童的最高发病率逐渐从2003年的3至5岁转变为2013年的12至14岁。2013年,PCR是丹麦用于百日咳实验室诊断的主要方法,而血清学是阳性结果百分比最高的方法。
We describe incidence and age distribution of laboratory-confirmed pertussis in Denmark from 1995 to 2013. Notification has been mandatory since 2007. Since 1997, an acellular monocomponent vaccine has been used. The latest epidemic occurred in 2002 with an incidence of 36 per 100,000; since 1995, only six infant deaths have been recorded. The inter-epidemic incidence lies below 10 per 100,000. In 1995, the mean age of confirmed cases was 9.2 years (95% confidence interval (CI): 7.9-10.5; median: 5.1), this gradually increased to 23.9 years in 2013 (95% CI: 22.0-25.8; median: 15.7). In 1995, 14% of laboratory-confirmed cases were 20 years and older, 43% in 2013. In the study period, the highest incidence among children was among those younger than one year with incidences between 84 and 331 per 100,000 in inter-epidemic periods (mean: 161/100,000) and 435 for the epidemic in 2002. After introduction of a preschool booster in 2003, the highest incidence among children one year and older changed gradually from three to five-year-olds in 2003 to 12 to 14-year-olds in 2013. In 2013, PCR was the primary method used for laboratory-diagnosis of pertussis in Denmark, while serology was the method with the highest percentage of positive results.
