Tuberculosis (TB) is an infectious disease caused by bacteria.
When a person who is sick with TB disease in their lungs coughs, sneezes, speaks or sings, they send TB germs into the air. If others breathe in those TB germs, they can become infected with TB and may get sick.
TB disease has serious symptoms, and can include:
- Coughing that lasts for three weeks or longer
- Weight loss
- Fever
- Night sweats
- Fatigue
If you or someone you know is experiencing any of these symptoms, make sure to speak to your doctor as soon as possible.
TB can be cured with medication.
