5. Deceleration of a pandemic wave 6. Preparation for future pandemic waves (described later) Figure B.1 includes a hypothetical influenza outbreak curve and the corresponding preparedness and response framework for novel influenza A virus pandemics with the CDC intervals. Figure B.1. Preparedness and response framework for novel influenza A virus pandemics: CDC intervals CDC = Centers for Disease Control and Prevention Progression thro ugh the intervals is not exclusively linear and is meant to enable jurisdictions to respond with actions that are appropriate for the level of activity occurring in their regions. These intervals, described in the publication Updated Preparedness and Response Framework for Influenza Pandemics, provide a common orientation and epidemiological picture of pandemic activity that can inform interventions. The intervals are flexible enough to accommodate the variable spread of a pandemic in different areas, allowing appropriate local, state, and federal actions for jurisdiction-specific conditions (for example, a jurisdiction with cases versus a jurisdiction with no cases but that is close to an area with cases). In addition, state and local health authorities could elect to implement interventions at different times within their jurisdictions, starting with communities that are first affected and then progressing to others. The state–local initiation, acceleration, deceleration, and preparation indicators can be out of step with the federal indicators. The published document provides additional details. 47
