Abstract:
An analytical, retrospective, and observational study was conducted aimed at identifying the risk factor associated with the development of tuberculosis in the intradomiciliary adult contacts of the sputum-positive carriers. One hundred twenty four subjects living with pulmonary tuberculosis patients were studied from January 1st 1997 to December 31st 2000, in Habana Vieja Municipality. 8% of the individuals living with tuberculosis patients with positive bacilloscopy got sick. The close contact with the index case from 7 to 59 months was a risk factor to catch the disease. Other risk factors identified were overcrowding, insufficient natural lightning, and inappropriate ventilation, which were present in 70% of the cohabiting subjects that got ill.

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.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
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 progression...
Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
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...
