What is the primary method through which Tuberculosis (TB) is transmitted?

The primary method through which Tuberculosis (TB) is transmitted is airborne or droplet transmission. When a person who has active TB coughs, sneezes, or even talks, they release tiny droplets containing the bacteria into the air. These droplets can remain suspended in the air for extended periods, allowing others in the vicinity to inhale them. This mode of transmission is particularly concerning in enclosed spaces where ventilation is poor, as it increases the likelihood of spreading the infection among individuals present.

Understanding this mode of transmission is crucial for implementing appropriate infection control measures in healthcare settings, such as using N95 respirators or masks for those at risk of exposure, ensuring proper airflow, and isolating affected individuals when necessary. This knowledge helps in preventing outbreaks and protecting public health, especially in environments like dental offices where close contact with patients occurs.
