A “Stone in the Pond” Approach to Contact Tracing: Responding to a Large-Scale, Nosocomial Tuberculosis Exposure in a Moderate TB-Burden Setting

A “stone in the pond” strategy is a practical approach to investigating large-scale nosocomial tuberculosis (TB) exposures. Here, we describe such a risk-stratified approach to contact tracing after a TB exposure that occurred over 5 months in a pediatric inpatient ward in a country with a moderate TB burden.
