1. (a) Examination for active tuberculosis (TB).

   1. (1) Persons with positive tuberculin skin tests or with skin-test conversions on repeat testing or after exposure shall be clinically evaluated for active TB. Persons with symptoms suggestive of TB shall be evaluated regardless of skin-test results.

   2. (2) If TB is diagnosed, appropriate therapy shall be instituted according to accepted medical practice.

      1. (A) Persons diagnosed with active TB shall be offered counseling and human immunodeficiency virus (HIV)-antibody testing.
      2. (B) The need for counseling and HIV testing should be stressed in persons diagnosed with active TB.

2. (b) TB infection without disease.

   1. (1) Persons who have positive tuberculin skin tests or skin-test conversions but do not have clinical TB shall be evaluated for preventive therapy. Persons with positive skin tests shall be evaluated for risk of HIV infection. If HIV infection is considered a possibility, counseling and HIV-antibody testing shall be strongly encouraged.
   2. (2) All persons with a history of TB or positive tuberculin tests are at risk for developing TB in the future. These persons shall be reminded periodically that they shall promptly report any pulmonary symptoms. If symptoms of TB shall develop, the person shall be evaluated immediately.
   3. (3) Routine chest films are not required for asymptomatic, tuberculin-negative persons. After the initial chest radiograph is taken, persons with positive tuberculin skin-test reactions do not need repeat chest radiographs, unless symptoms develop that may be due to TB.
