Pandemic Influenza Plan 2007

Arrow BulletChapter 3: Key Planning Assumptions

Influenza, whether seasonal or pandemic, has always been an unpredictable disease. While an influenza pandemic is considered inevitable, its timing and impact cannot be predicted and will not be known until the pandemic virus emerges. The factors that will affect the impact of a pandemic include:

  • Characteristics of the virus - attack rate, affected age groups, virulence (rates of complications and death) and speed of spread;
  • Effectiveness of the response – vaccines, antiviral drugs, and public health measures; and
  • Public behaviour.
