This study describes the epidemiologic surveillance necessary to detec
t pediatric pulmonary tuberculosis in the two populations most often a
ffected by the disease, American-born children of minority race or eth
nicity and foreign-born children. We reviewed the records of 34 cases
of pediatric pulmonary tuberculosis in racial or ethnic minorities. Mo
st children were asymptomatic and smear- and culture-negative. Contact
tracing is essential, and, in the absence of bacteriologic confirmati
on, a positive tuberculin skin test and an abnormal chest roentgenogra
m are still the only clues to a clinical diagnosis.
