Tuberculosis (TB) Information

Pulmonary Tuberculosis ( TB ) : Chest x-ray show

Tuberculosis (TB) is an airborne disease that can occur in any part of the body (the brain, spine, lymph nodes, etc), but it most often causes infection in the lungs.

TB is spread from person to person through the air. This happens when a person with TB of the lungs sneezes, coughs, speaks, or sings and a person close by breathes in the MTB bacteria.

Not everyone with TB gets sick. A person can have TB disease or TB infection (“LTBI”), both of which are treatable with medication. If someone is not treated properly, TB can be a severe or deadly disease. People who have LTBI and are not treated properly can develop TB disease and become sick.

General information about TB and a variety of TB topics is available on US Centers for Disease Control and Prevention website.

The Role of CDPH

Although CDPH no longer operates its own TB clinics, CDPH continues to provide TB clinical services through a contract with the Cook County Health and Hospitals System (CCHHS). The CCHHS “Chest Clinic” provides care for Chicago residents diagnosed with or suspected of having TB, contacts to infectious cases, and recently arrived immigrants and refugees. The clinic is staffed by members of the CCHHS Pulmonology and Critical Care Division, and all TB-related services are provided free-of-charge. Appointments are through CDPH referral only.

Other services include:

  • Nurse case management of all individuals with suspected or confirmed TB
  • Directly observed therapy (DOT)
  • Contact investigations
  • Housing for patients experiencing homelessness during TB treatment
  • Medical and infection control consultations
  • Surveillance, epidemiology, and research
  • TB education and training
