Let's Talk TB

There are two types of TB conditions: TB disease and Latent TB infection.

Tuberculosis disease

​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.

Latent TB infection

Latent tuberculosis (TB) infection is a "hidden" infection caused by exposure to TB germs.

If you breathe in TB germs, your body may fight off the germs, or the germs may hide in your body for a long time before making you sick. This is called TB infection or latent TB infection.

These hidden germs cannot spread from person to person, but can become infectious overtime unless it is treated with medication, which can prevent TB germs from growing and making you sick.
