Transmission Of childhood tuberculosis risk factors associated with an unidentified index case and outbreak evolution in Barcelona (1987-2007).

摘要

The objective of the study was to examine the factors associated with unidentified tuberculosis (TB) index cases (1987-2007) and to describe outbreaks (2000-2007) of childhood TB cases in Barcelona, Spain. Contact tracing seems to be fundamental in index case identification, but improvement could be made among older children and cases of extrapulmonary TB or pulmonary TB with sputum microscopy results.
