A TB contact is a person that has been exposed to TB. TB contacts are ranked from high priority to low. High priority means either the person has had prolonged EXPOSURE, or that the person is HIGHLY susceptible to becoming infected and progressing to TB DISEASE — children under the age of 5 or persons infected with HIV or on immunosuppressive therapy. Contacts should be promptly tested once exposure is known, and tested again about 10 WEEKS after the last known exposure. If either test is positive, the person is considered infected and REQUIRES additional follow-up and treatment.
