  How Do You Catch Tuberculosis (TB)?

The TB Germ is passed in to the air….   You breathe
when a person                                 the
                                           TB germ
      with                                     into

 Latent TB Infection

•You have breathed the TB germ
Into your lungs                         LUNGS

• Your body builds a wall
around the TB germ
• The TB germ is “sleeping”

• You do Not feel sick and           WALL TB GERM
can Not make anyone else sick

9 months

    Treatment of Latent TB Infection

       Isoniazid(INH) is taken for 9 months to kill the
        “sleeping” TB germ.

       This stops the bacteria from “waking up” and making a
        person sick with TB Disease.

       Treating TB infection is very important for people who
        have conditions that make their body weak.

       Most people who take TB pills have no problems.

How Do You Get TB Disease?

  If you have Latent TB infection and your body
  becomes weak, the wall around the TB germ can
  break down.

                               If the wall breaks down,
                               The TB germs will
                                “wake up” and make
                                you sick.

                               This is TB disease

      Conditions That Make Your
Body Weak and Cause TB Infection
   to “Wake Up” to TB Disease
   HIV/AIDS                           Organ Transplants

   Cancer                             X-rays that show old TB
   Medications that                   Substance abuse
    suppress immunity (e.g..           Silicosis
                                       Leukemia
   Kidney disease
                                       Lymphoma
People with these conditions should be checked once a
year for TB Infection and TB Disease
