How is tuberculosis primarily transmitted?

1. Direct contact with skin

2. Airborne particles

3. Contaminated food or water

4. Close physical contact

The correct answer is: Airborne particles

Tuberculosis (TB) is primarily transmitted through airborne particles, which occur when a person with active TB coughs, sneezes, talks, or otherwise expels infectious droplets into the air. These droplets can remain suspended in the air for extended periods and can be inhaled by individuals who are nearby, leading to the potential for infection. This mode of transmission highlights the importance of air quality and ventilation in settings where individuals may be at risk, as well as the need for protective measures to reduce the spread of TB, such as wearing masks or employing proper isolation techniques in healthcare environments. Understanding this transmission route is crucial for effective public health strategies and individual safety in managing and preventing TB outbreaks.
