Distinct Risk Factors for Clinical and Bacteriologically Confirmed Tuberculosis among Child Household Contacts in a High-Burden Setting.

The identification and screening of children at high risk of tuberculosis is essential to the control and prevention of child tuberculosis (TB). BUTIMBA, an active case finding and household contact-tracing project implemented between 2013 and 2015 in Eswatini, evaluated 5,413 contacts of 1,568 index cases, of whom 82 (1.5%) were diagnosed with TB disease.
