High rates of tuberculosis infection among children from Ciutat Vella District, Barcelona, 1996-1997.
With tuberculosis (TB) rates of over 160/100,000 in 1997, Ciutat Vella District, Barcelona, is the main community focus of TB in the city. For the purpose of TB screening, 415 children >2 years old from that district received a tuberculin skin test (TST); 27 (6.6%) (95%CI 4.5-9.3) were found to be infected but disease-free. The frequency of a positive TST increased significantly with age, from 0% in the 2-4 year age group to 14.6% in 10-14 year olds. Three culture-positive source adults, two of them sputum smear-positive, who were not previously known were traced from six TST-positive children. Previous BCG vaccination was not associated with a positive TST. These data support the use of universal TST screening in children living in Ciutat Vella District, Barcelona, as a means of identifying and treating TB cases.
