What is a common method of transmission for tuberculosis?

The transmission of tuberculosis (TB) primarily occurs through the inhalation of airborne droplets. When an individual with active TB coughs, sneezes, or speaks, they release tiny droplets containing the Mycobacterium tuberculosis bacteria into the air. Other individuals can then inhale these droplets, leading to potential infection. This is why TB is classified as an airborne disease, necessitating specific precautions to prevent spread in healthcare settings and other crowded environments.

While other transmission methods, such as contact with contaminated surfaces and consumption of unpasteurized dairy products, are concerning for different infections, they are not typical transmission routes for TB. Additionally, TB is not vector-borne, meaning it is not transmitted through insects or other animals. Understanding this mode of transmission is critical for proper public health measures and personal protective equipment use in managing and controlling TB outbreaks.
