[National Strategy for Pandemic Influenza] Implementation Plan Three Year Summary [open html - 904KB]
"This Three Year Summary provides a historical record to report the Federal Government's progress in addressing actions due to be completed within 36 months of the initial release of the Implementation Plan and reflects that progress as of April 30, 2009. Although the closely-monitored H5N1 influenza strain did not evolve into a human pandemic strain over those three years, a different influenza virus caused a pandemic in 2009. In late April 2009, human outbreaks associated with a novel influenza virus, 2009 H1N1 Influenza A, were confirmed in Mexico and the United States. On June 11, 2009, the WHO officially declared an influenza pandemic and raised its pandemic alert phase to 6. Fortunately, however, the characteristics of 2009 H1N1 influenza virus have not caused the economic or societal interruptions anticipated in the Implementation Plan and its actions. 2009 H1N1 disease severity has been generally similar to what is seen during regular influenza seasons (although different age groups have been predominantly affected, with most cases, and most severe cases, occurring in older children and adults less than 65 years of age)."
