在高结核病 (TB) 环境中,Mycobacterium结核病 (M. tb) 的社区传播是显著的. 在整个人口中发现活跃病例可能是必要的,以控制结核病扩散到家庭之外.
科学领域:
- 传染病流行病学 传染病流行病学
- 基因组流行病学 基因组流行病学
- 公共卫生 公共卫生
背景情况:
- 结核病 (TB) 在高负担国家的传播可能超出家庭范围.
- 了解社区传播对于有效的结核病控制策略至关重要.
研究的目的:
- 估计结核病指数病例的家庭和社区接触者之间的结核病发病率和发病率.
- 使用全基因组测序 (WGS) 分析结核病传播模式.
主要方法:
- 关于印度尼西亚班敦的肺结核指数病例的家庭和社区接触者的前性研究.
- 结核病查,唾液分析 (显微镜,培养,Xpert MTB/RIF) 和DNA隔离.
- 全基因组测序 (WGS) 和单核酸多态性 (SNP) 分析以定义传输事件.
主要成果:
- 与邻居接触者相比,在家庭接触者中观察到较高的结核病患病率和发病率.
- WGS分析显示,结核病传播的很大一部分发生在家庭之外,与索引病例的联系有限.
- 确定了25个Mycobacterium结核病遗传集群,表明社区传播广泛.
结论:
- 邻居接触者显示结核病的发病率和流行率较低,但占病例数量很大.
- 从指数病例到邻居的有限直接传播表明无控制的社区范围的结核病传播.
- 在高结核病负担的环境中,发现全人口活跃病例可能是必要的策略.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Transmission-based Precautions II: Airborne and Protective Environment
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
