Between the people and TB, there’s you
TB is highly contagious. The World Health Organization (WHO) states that tuberculosis (TB) is spread from person to person through the air. When people with TB cough, sneeze or spit, they propel the TB germs into the air. A person needs to inhale only a few of these germs to become infected. That is why accurate, early diagnosis is so crucial. People with active TB can infect 5-15 people through close contact over the course of a year.1 In other words, a person with undiagnosed active TB can rapidly create a public health crisis without even knowing it.
