- We report the results of investigating and managing a tuberculosis (TB) exposure in apostpartum care center. Among the contacts exposed to a nursing assistant with subclinical TB,5 of 44 neonates (11.4%) had positive tuberculin skin tests (TSTs) at 3 months of age, and all theTST-positive neonates received the Bacille Calmette-Guérin vaccination. Seven of 28 healthcareworkers (25.0%) and 1 of 3 household contacts (33.3%) were positive in the initial or repeatedinterferon-gamma release assay. None of the contacts developed TB disease during the studyperiod. Annual TB examinations of healthcare personnel at a postpartum care center under theTuberculosis Prevention Act in South Korea enabled the early detection of subclinical TB, whichreduced the risk of transmission to neonates under strict coronavirus disease 2019 preventionmeasures.
