Thursday, September 19, 2024 | Tuberculosis Contact Investigation: Principles and Practice
Speaker: Dr Elizabeth Rea, MD, MSc, FRCPC, Tuberculosis Program Toronto Public Health
The recently updated Canadian TB Standards, 8th Edition, emphasize the importance of thoughtful risk-based prioritization for contact investigation, using an iterative approach. This presentation will review the principles of TB contact investigation, including transmission risk assessment, prioritizing follow-up based on the source case’s likely infectiousness, the nature of the exposure(s), and factors that increase immunologic vulnerability of exposed individuals to TB disease. The usefulness and limitations of using a structured tool to support risk-based contact investigation will also be discussed. Case studies of TB contact investigations will be presented, applying the principles of contact investigation, and exploring practice-based implementation experiences and lessons learned, from the perspective of a local public health unit.
