The Ultimate Swine Flu Survival Guide
 
On August 30th, 2009, the CDC adopted a new case definition for reporting of influenza-related hospitalizations and deaths.  It is no longer necessary to report 2009 H1N1 influenza cases separately; the new system allows for reporting of all types or subtypes of influenza in aggregate.  With the new definitions, and the zero point reset to August 30th, "22,364 laboratory-confirmed influenza associated hospitalizations and 877 laboratory-confirmed influenza associated deaths" have been reported to the CDC from August 30 - November 7, 2009.   See CDC H1N1 Flu Update for the week ending November 7, 2009.
