Tuberculosis (TB) is a potentially serious infectious disease that mainly affects your lungs. The bacteria that cause tuberculosis are spread from one person to another through tiny droplets released into the air via coughs and sneezes. Once rare in developed countries, tuberculosis infections began increasing in 1985, partly because of the emergence of HIV, the virus that causes AIDS.

Tuberculosis (TB) is a disease caused by Mycobacterium tuberculosis and spread from person to person through the air. TB usually affects the lungs (typically the primary site of inoculation), though it can affect any organ.

If left untreated or treated improperly, TB can kill, so you must be able to recognize the signs of respiratory tuberculosis.
