Outbreak Line Listing: Why the Details Matter in Infection Prevention and Control

In this episode of The Infection Control Exchange Podcast, we take a deep dive into one of the most important—and often underappreciated—tools in outbreak management: the line list.

Using an outbreak scenario, this episode walks through the structure of a line list and explains how each data element contributes to effective outbreak control.

Topics covered include:

• Case identification and unit tracking• Symptom documentation and baseline considerations• The importance of symptom onset timelines• Intervention tracking, including vaccination and antiviral• Identifying complications and severity indicators• Interpreting laboratory test results• Common mistakes that impact outbreak response

Line lists are more than documentation—they are the foundation for surveillance, decision-making, and communication during outbreaks.

This episode is particularly relevant for IPAC professionals, acute care teams, long-term care teams, and public health practitioners.
