Investigation Guidance
Emerging and Acute Infectious Disease Guidelines (EAIDG) - Updated 2025
The purpose of this handbook is to provide a centralized resource for outbreak and reportable disease investigations to local and regional health departments in Texas. This handbook is intended as a tool to help local and regional public health staff with their surveillance activities and investigations. Our hope is that this handbook will continue to grow over the years and highlight some of the best investigation practices in the state. Information covers control measures, case definitions, case statuses, laboratory collection/shipping procedures and more.
