How does tuberculosis (TB) affect your body?

ANSWER

There are two forms of the disease:

�Latent TB: You have the germs in your body, but your immune system stops them from spreading. That means you don�t have any symptoms and you�re not contagious, but the infection is still alive in your body and can one day become active.

�Active TB disease: This means the germs multiply and can make you sick. You can spread the disease to others. Ninety percent of adult cases of active TB are from the reactivation of a latent TB infection.
