How TB Spreads
Whenever a person with tuberculosis coughs or sneezes, they propel millions of infectious bacteria into the air through droplets of moisture.

Though the germs are incapacitated, as long as they are within the tubercle, the tubercle can break down over time and allow the germs to escape and multiply, causing the individual to become ill.
