Tuberculosis (TB) is an infectious bacterial disease caused by Mycobacterium tuberculosis, which most commonly affects the lungs. It is transmitted from person to person via droplets from the throat and lungs of people with the active respiratory disease.
TB causes far more deaths than any other infectious diseases worldwide. It infects one-third of the world’s population, and kills three million people every year (a quarter of the world’s preventable deaths).
The Harris County Public Health (HCPH) TB Elimination Program offers a variety of services aimed at TB prevention and control. These services are under the direction of a physician who – along with nurses and other TB Program staff – helps carry out the local fight against TB.
