How is tuberculosis primarily transmitted?

Tuberculosis (TB) is primarily transmitted through airborne droplets when a person with active pulmonary TB coughs, sneezes, or otherwise expels respiratory secretions into the air. These droplets can be inhaled by others in close proximity, leading to the spread of the Mycobacterium tuberculosis bacteria. This mode of transmission is particularly significant in crowded or poorly ventilated environments, where the risk of inhaling these infectious droplets is higher.

Other routes of transmission, such as contaminated food, direct contact with skin, or blood transfusions, do not play a significant role in the spread of TB. While it is important to maintain proper hygiene and safety measures to prevent infections, the primary concern with tuberculosis revolves around respiratory transmission. Understanding this is crucial for implementing effective public health strategies to control and prevent outbreaks of TB.
