概括

在西澳大利亚,从2000年到2018年,侵袭性B型 estreptococcal (iGBS) 感染的数量增加,影响老年人的比例越来越大. 建议针对这一人口群体制定有针对性的预防策略.

科学领域:

传染性疾病传染性疾病
流行病学流行病学
公共卫生公共卫生

背景情况:

新生儿和产后败血症是入侵性B组链球菌 (Streptococcus agalactiae; iGBS) 感染的关键表现.
国际数据突出显示iGBS感染在非怀孕的成年人中的重要性.

研究的目的:

确定2000年至2018年在西澳大利亚 (WA) 的iGBS感染的发病率,住院时间和死亡率 (30日和90天).

主要方法:

一个回顾性,基于人口的研究,利用病理学,住院和死亡登记的相关数据.
包括从无菌地点分离出来的GBS儿童和成年人或被诊断出患有医院基础的iGBS感染.

主要成果:

确定了2861例病例,768例 (26.8%) 是婴儿 (0-1岁).
在研究期间,发病率上升,在2018年达到每10万人口中的9.5例.
虽然婴儿病例比例下降,但老年人群的相对发病率增加;30天死亡率为3%.

结论:

在2000年至2018年期间,华盛顿州的iGBS病例增加,老年人明显增加.
预防措施,可能包括疫苗接种,应专注于老年人群,以减轻这一趋势.
