The good news is that with proper medication, TB can be cured.

 How is TB spread?        Spreading

TB is spread through the air from one person to another. The bacteria get into the air when a person with TB disease of the lungs or throat coughs, shouts, sings, or sneezes. People nearby may breathe in the bacteria and become infected. You may have been exposed to TB if you spent a lot of time near someone with TB disease of the lungs or throat. Most people get TB from a family member, spouse, friend, or close coworker. You are not likely to get TB from someone coughing in a restaurant or on a bus. And, it is not spread by shaking hands or sharing dishes, drinking glasses, or clothing.
