This general planning guide has three purposes. First, it provides background information on pandemic influenza. Second, it outlines Toronto Public Health’s (TPH) role during an influenza pandemic. Third, it identifies issues and critical elements of emergency preparedness that businesses should consider in planning for an influenza pandemic. This guide will help planners develop more detailed business continuity plans for their organization. Although TPH will identify broad public health issues, every organization must plan for the specific disruptions it will face during a pandemic.
