What is Tuberculosis?
Tuberculosis (TB) is a contagious infection that is spread through the air by coughing and sneezing. When infectious people cough, sneeze, talk, or spit, they propel TB germs into the air. To become infected, a person needs only to inhale a small number of these germs from an actively infected TB person.
