"A new influenza strain, influenza A (H5N1), is spreading through bird populations across Asia, Africa, and Europe, infecting domesticated birds, including ducks and chickens, and long-range migratory birds. In response to this threat, the President issued the National Strategy for Pandemic Influenza on November 1, 2005. The Strategy outlines the coordinated Federal Government effort to prepare for pandemic influenza. This Implementation Plan for the National Strategy for Pandemic Influenza further clarifies the roles and responsibilities of governmental and non-governmental entities, including Federal, State, local, and tribal authorities and regional, national, and international stakeholders, and provides preparedness guidance for all segments of society. It also provides guidance for families and individuals to ensure appropriate personal protection. The Implementation Plan represents a comprehensive effort by the Federal Government to identify the critical steps that must be taken immediately and over the coming months and years to address the threat of an influenza pandemic. It assigns specific responsibilities to Departments and Agencies across the Federal Government, and includes measures of progress and timelines for implementation to ensure that we meet our preparedness objectives. This Plan will be revised over time. The pandemic threat is constantly evolving, as is our level of preparedness."
