在64岁以上的成年人中,COVID-19的制措施显著减少了肺炎球菌携带. 关闭期间的病率下降,但随着限制的放松,病率恢复到大流行前的水平,这突显了公共卫生干预措施的影响.
科学领域:
- 微生物学 微生物学
- 流行病学 流行病学
- 公共卫生 公共卫生
背景情况:
- 制COVID-19的措施影响了传染病的动态.
- 在大流行期间,侵入性肺炎球菌病的负担下降.
- 在此期间,关于成年人肺炎球菌携带率的数据有限.
研究的目的:
- 在COVID-19大流行期间调查老年人肺炎球菌携带率.
- 评估与流行病相关的缓解措施对运输流行率的影响.
主要方法:
- 一项涉及64岁及以上成年人的前性研究.
- 从2019年1月到2021年12月收集鼻腔和口腔口的抽样.
- 使用*lytA/piaB*PCR检测 *Streptococcus pneumoniae* DNA.使用*lytA/piaB* PCR检测 *Streptococcus pneumoniae* DNA.使用*lytA/piaB* PCR检测 *Streptococcus pneumoniae* DNA.使用*lytA/piaB* PCR检测 *Streptococcus pneumoniae* DNA.使用*lytA/piaB* PCR检测 *Streptococcus pneumoniae* DNA.使用*lytA/piaB* PCR检测
主要成果:
- 总共有1556名参与者被纳入,平均年龄为74岁.
- 在9.4%的口和2.2%的鼻抽样中检测到 *Streptococcus pneumoniae* DNA.
- 运输率从封锁前的12.9%下降到封锁期间的4.2%,然后在重新开放时反弹至12.1% (P = .0009).
结论:
- 在COVID-19缓解措施期间,肺炎球菌携带者患病率显著下降.
- 随着公共卫生限制的解除,运输率恢复到大流行前的水平.
- 这些发现强调了非药物干预对呼吸道病原体传播的影响.
