- 流行病学 流行病学
- 传染性疾病 传染性疾病
背景情况:
- 百日咳 (百日咳) 是一种高度传染的呼吸道疾病,对幼儿构成重大风险.
- 家庭传播是 pertussis 传播的主要途径,受治疗和预防时间的影响.
- 了解传播动态对于有效的控制策略至关重要.
研究的目的:
- 为了分析家庭中继性咳传播的风险.
- 为了确定是否延迟诊断 pertussis 放大家庭传播的风险.
主要方法:
- 使用国家行政索赔数据库进行了两项基于人口的研究.
- 采用分层的月度发病率模型来评估咳暴露风险.
- 利用后勤回归来评估诊断延迟与家庭层面的传播风险之间的关联.
主要成果:
- 接触过百日咳的家庭成员的入学者患病率比率 (938.99) 显著更高.
- 索引病例的诊断延迟使二次家庭传播的几率增加了5.10倍.
- 在较长的诊断延迟和传播风险增加之间观察到统计学上显著的相关性 (P < 0.0001).
结论:
- 百日咳在家庭中具有很高的二次传播率.
- 迟迟诊断 pertussis 是一个关键因素,提高了家庭传播的可能性.
