Tuberculosis is primarily transmitted from one person to another through the air. Here are the steps:

1. When a person with active Tuberculosis (TB) in their lungs or throat coughs, sneezes, speaks, sings, or laughs, they expel tiny droplets that contain the TB bacteria into the air.

2. These tiny droplets can stay in the air for several hours, depending on the environment.

3. People who are in the same room or area with the person with active TB can inhale these tiny droplets, thus getting the TB bacteria into their own lungs.

4. Once in the lungs, the bacteria can settle and begin to grow, leading to a TB infection. Not everyone who inhales the bacteria will become sick. The immune system can often fight off the bacteria, resulting in latent TB.

5. If the immune system cannot fight off the bacteria, or if the bacteria become active at a later date, the person can develop active TB disease.

6. The person with active TB disease can then spread the bacteria to others through the same process.

It's important to note that TB is not easily spread. It usually takes prolonged close contact with a person with active TB disease for transmission to occur. It's not typically spread through brief contact or by touching surfaces that a person with TB has touched.
