Lancet Infect Dis:5岁以下儿童百日咳流行病学研究

2017-06-14 zhangfan MedSci原创

相比于1999-2003年的统计(3060万的5岁以下儿童病例以及390000死亡),百日咳病例数及死亡人数均显著下降。

近日,研究人员对5岁以下儿童的区域和全球百日咳病例和死亡情况进行了研究。研究人员对2014年以来百日咳病例和死亡进行估计。根据WHO的临床定义:咳嗽持续至少2周,阵发性咳嗽、吸气哮或咳嗽后呕吐定义百日咳病例,使用联合国的人口估计和国家百日咳疫苗接种覆盖率联合国儿童基金会的数据。估计一,两和三个剂量疫苗接种,覆盖率及小于1岁的婴幼儿和1岁–4年的孩子疫苗接种的有效性。研究估计在2014年,共发生2401万百日咳病例,导致160700名5岁以下儿童死亡,其中非洲占绝大多数(780万[33%]的病例数以及92500[58%]的死亡数)。估计510万(21%)病例以及85900(53%)发生在1岁以下。敏感性分析表明,全球百日咳病例约700万至4000万,死亡38000人至670000人。研究表明,相比于1999-2003年的统计(3060万的5岁以下儿童病例以及390000死亡),百日咳病例数及死亡人数均显著下降。加强国家一级决策监督对改善和控制百日咳十分重要。原始出处:Karene Hoi Ting Yeung et al.
