Causes and Risk Factors

Tuberculosis (TB) is a complex infectious disease with specific origins and transmission patterns that impact millions worldwide. Understanding its causes and risk factors is crucial for prevention and management⁷.

Bacterial Origins of Tuberculosis

TB is caused by Mycobacterium tuberculosis, a bacterium that mainly attacks the lungs but can spread to other parts of the body⁷. Many people carry a latent TB infection, where bacteria stay inactive and don’t cause symptoms⁸.

Common Risk Factors

Weakened immune systems due to HIV, diabetes, or medical treatments⁸
Living in crowded environments like shelters or prisons⁸
Frequent travel to high-TB regions in Asia, Africa, and Latin America⁸
Working in healthcare or high-exposure settings⁸

Transmission Methods

TB spreads through airborne transmission when an infected person coughs, speaks, or sings. Germs can stay in the air for hours, making indoor, poorly ventilated spaces very dangerous⁷.

TB Transmission Risk	Likelihood
Close daily contact	High
Outdoor environments	Low
Indoor, confined spaces	Very High

Understanding drug-resistant TB is critical, as some strains can be harder to treat. People with weakened immune systems are more likely to develop active TB disease⁹.

Approximately 25% of the world’s population has latent TB, which can potentially develop into active disease⁹.
