www.fludb.orgPublic Health Impact of InfluenzaSeasonal flu epidemics occur yearly during the fall/ winter months and result in 3-5 million cases of severe illness worldwide.More than 200,000 people are hospitalized each year with seasonal flu-related complications in the U.S.Approximately 36,000 deaths occur due to seasonal flu each year in the U.S. Populations at highest risk are children under age 2, adults age 65 and older, and groups with other comorbidities.

2) Asian flu (1957 - 1958)- Subtype H2N2- 1 > 1.5 million deaths

3) Hong Kong flu (1968 - 1969)- Subtype H3N2- between 750,000 and 1 million deaths

4) 2009 H1N1- Subtype H1N1- > 16,000 deaths as of March 2010
