Tuberculin skin test screening in schoolchildren in the United States.
OBJECTIVE
To determine the current practices and results of tuberculin skin test (TST) screening of schoolchildren in the United States.


METHODS
Tuberculosis program staff in all states and the District of Columbia were asked about current requirements, practices, and results of school-based TST screening.


RESULTS
Thirty-four states and the District of Columbia (69%) reported no current statewide statutes or policies for tuberculin screening of schoolchildren, and 10 (19%) reported having statewide requirements. In 6 states (12%), requirements were instituted at the local level, and 24 localities in these states were known to require screening. Of the 34 areas requiring screening, 18 (53%) screened all new entrants, 7 (21%) screened children in specific grades, and 9 (26%) used other criteria for screening. TST results were collected for 26 (76%) of 34 areas, and 6 areas collected results of follow-up evaluation of tuberculin-positive children. Additionally, 8 localities in 7 states with no screening requirements conducted tuberculin surveys. Sixteen areas provided results. In 7 of the 8 areas that collected information about birthplace, less than 2% of US-born children were tuberculin positive; foreign-born children had rates 6 to 24 times higher than US-born children. TST screening identified new cases of tuberculosis, less than 0.02% of the children screened.


CONCLUSIONS
School-based tuberculin screening identified low rates of positive TST results in US-born children. Resources should be directed toward screening children at high risk for tuberculous infection, as recommended by the American Academy of Pediatrics and the Advisory Committee for Elimination of Tuberculosis.
