•Nursing Home Residents
•Prisoners
•Alcoholics and IV Drug abusers

TB Disease vs. TB InfectionTB Disease:
•Person is sick with germs that are active in the body
•Usually have one or more symptoms of TB
•Can pass disease on
•Permanent body damage and death can occur
•Medicine is prescribed that can cure TB
TB Infection:
•Person is healthy
•Strong immune system
•No Symptoms
•Cannot spread the infection
•Can develop TB disease in the future
•Medicine prescribed to prevent development of TB disease
Diagnosis of TB•Skin Test
•Doctors Office or local Health Department
•If positive other tests will be done to see if you have infection vs. disease
•Small needle used to implant tuberculin under the skin
•Usually done inside of your forearm
•Test is read in 48 to 72 hours to check for reaction
•Size of reaction is measured
•Less than 10mm is negative
Negative vs. PositiveNegative Test:
•Usually means person is not infected
•Maybe falsely negative if person has been recently infected
•Usually takes 2 to 10 weeks after exposure for test to become positive
Positive Test:
•Usually means the person has been infected with the TB germ
•Does not necessarily mean person has TB disease
•Other testing such as X-Ray or Sputum testing will be ordered
Treatment of TB•Compliance with medications is mandatory
•Common medications include INH and Rifampin
•Routine follow up Chest X-Rays
•Routine follow up with Physician
