TB disease means your immune system can't fight the TB bacteria you have been infected with. TB can occur anywhere in the body, but for most people, it will infect the lungs. People with TB disease in the lungs can spread the infection to others.
People with TB disease in the lungs may have:
A bad cough lasting 3 weeks or longer
Pain in the chest
Cough up blood or sputum
Weakness or fatigue
Sweating at night
We work with clinics and hospitals to make sure people with active tuberculosis are quickly identified. We help people who had contact with a person who has active TB get tested and if needed, get treated.
