"This report is an update to the previous reports to Congress that were provided in June and December 2006. This report covers all activities from December 2005 to June 2007. The report covers both the December 2005 emergency supplemental (PL 109-148) and the June 2006 emergency supplemental (PL 109-234). In August 2005, animal outbreaks of highly pathogenic H5N1 had been reported in twelve countries around the world with 112 total human cases confirmed in four of those countries. […]. Overall, 61 percent of human cases have been fatal. Once a pandemic begins, time will be a critical factor in our ability to accomplish the necessary production and delivery of vaccines and other medical countermeasures required to mitigate the pandemic. On November 1, 2005, the President requested a total of $7.1 billion in emergency funding for pandemic influenza preparedness activities, of which $6.7 billion was for implementation of the HHS Pandemic Influenza Plan. This funding was requested in FY 2006 to fund a three-year preparedness effort to ensure the Nation could effectively respond in the event of a pandemic. In December 2005, Congress appropriated $3.3 billion in emergency funding for HHS in a FY 2006 supplemental, for the first year of the HHS Pandemic Influenza Plan. In June 2006, Congress appropriated $2.3 billion for HHS in emergency funding in a second FY 2006 supplemental for the second year of the HHS Plan. In addition, HHS has requested $870 million in the FY 2008 President's Budget in one-time funding to continue these efforts."
