What is the main infection affected by Tuberculosis (TB)?

Tuberculosis (TB) primarily affects the lungs, which is why the answer is correct. TB is a bacterial infection caused by Mycobacterium tuberculosis, and the most common form of the disease is pulmonary TB. This version of TB typically begins in the lungs and can be spread through the air when an infected person coughs or sneezes.

While TB can affect other parts of the body, including the kidneys, spine, and brain, the lungs are the primary site of infection, making them crucial in understanding how TB is transmitted and treated. Knowing this is essential for recognizing the symptoms associated with pulmonary TB, such as chronic cough, chest pain, and coughing up blood, which are not typically associated with infections in other organs like the skin, heart, or kidneys. Understanding the primary area of infection helps EMTs in assessing patients and providing appropriate care and transport to medical facilities for further evaluation and treatment.
