Tuberculosis (TB) control is slow globally. Evidence suggests most Mycobacterium tuberculosis transmission occurs indoors, indicating environmental modifications could significantly impact TB control efforts.
Area of Science:
- Epidemiology
- Molecular Epidemiology
- Mathematical Modeling
Background:
- Global tuberculosis (TB) incidence decline rates are suboptimal.
- Current TB control strategies, like DOTS, show limited impact.
- Most Mycobacterium tuberculosis transmission likely occurs in indoor congregate settings.
Purpose of the Study:
- To review evidence on TB transmission in indoor settings.
- To propose environmental modifications as a TB control strategy.
- To suggest a research agenda for TB environmental interventions.
Main Methods:
- Review of basic epidemiological data.
- Analysis of molecular epidemiological findings.
- Evaluation of mathematical modeling studies.
Main Results:
- Consistent evidence points to indoor congregate settings as primary TB transmission sites.
- Environmental modifications in these settings could substantially reduce TB transmission.
- Existing technologies can be implemented without reliance on scarce healthcare workers.
Conclusions:
- Targeting indoor environments offers a promising, feasible strategy for TB control.
- Further research is needed to guide effective environmental intervention implementation.
- Non-healthcare worker-dependent interventions are crucial for high-burden TB settings.

Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
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.

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...
