If states are reporting aggregate influenza hospitalizations and deaths, how will you tell what percentage of cases is due to 2009 H1N1 and what percentage is due seasonal influenza viruses?
Due to CDC’s new case definitions, there will be no definitive way to differentiate between hospitalizations and deaths due to seasonal influenza versus those due to 2009 H1N1 influenza from aggregate reporting. And some deaths that are not due to influenza specifically will be included. However, information on the proportion of influenza viruses that are 2009 H1N1 versus seasonal influenza will continue to be reported in FluView from the virologic surveillance system. (For example, as of August 29, 2009, 97% of all subtyped influenza A viruses being reported to CDC were 2009 H1N1 viruses.)
How accurate a representation are these numbers?
Laboratory-confirmed data is thought to be an underestimation of the true number of cases because most people will not be tested for influenza.
However, influenza and pneumonia syndrome hospitalizations and deaths may be an overestimate of actual number of flu-related hospitalizations and deaths because that diagnostic category includes other illnesses.

you can identify the codes (J-10) and more, but this does not shed light on the statistics exactly.
The elderly are the group hardest hit by pneumonia each year. In 2002 close to 65,000 people died from pneumonia, 90 percent of those deaths were in those 65 years or older. Also at high risk are post-operative patients, people with chronic illnesses such as lung disease, and those living in a nursing home or other chronic care facility.
The flu is not scary. It is commonplace.
