The Health Department:
- Provides recommendations and assistance regarding diagnosis and treatment.
- Provides free laboratory testing, chest x-rays, medications and case management services for Fairfax County residents.
- Conducts contact investigations to identify exposed individuals and provide appropriate follow-up.
- Offers screening services to identify risk for developing TB for a small fee. (Refer to the schedule of the services offered at Health Department clinics.)
Health care providers with inquiries about about TB or other communicable diseases can call 703-246-2433.
- TB is a bacterial disease spread from person to person by close, prolonged exposure to infected airborne droplets, such as from a cough or sneeze.
- TB bacteria are put into the air when a person with active TB disease of the lungs or throat coughs, sneezes, speaks or sings. People nearby may breathe in these bacteria and become infected.
- TB is not spread by shaking someone’s hand, sharing food or drink, touching bed linens or toilet seats, sharing toothbrushes or kissing.
- TB is treatable and curable.
- Effective April 4, 2016, the Health Department uses a blood test called the QuantiFERON® TB test (QFT) for everyone ages 5 years and older. The cost is $45; however, in most cases there is no charge if the test is for school entry. The QFT is a more accurate test that requires a single visit to a Health Department clinic.
The Health Department will continue to use a tuberculin skin test
(TST) for children less than 5 years old.
- A positive TB test does not indicate that a person is sick or contagious. A positive TB test means that a person has been infected with the TB germ and that his or her body has developed a sensitivity to the germ.
The Health Department provides chest x-rays and evaluation for TB
disease when appropriate.

- Medication is prescribed for persons who test positive for TB infection as demonstrated by a positive skin test and no evidence of TB disease. The medication is safe and effective. It must be taken as prescribed, usually every day, for 4 to 9 months.
- Active TB disease is also treatable with medications prescribed by a physician. Active TB disease is curable as long as the medications are taken as directed by the physician. Active TB disease is serious and requires medical therapy, which is free to all Fairfax County residents.
