H1N1 (Swine Flu)
H1N1- Influenza A virus subtype

H1N1 is a strain of the influenza virus that is new to humans. Studies have found that the virus carries two genes from flu viruses that are normally found in pigs (swine); thus the alternative name swine flu.

Beginning in the spring of 2009, the H1N1 flu was a new virus that spread quickly throughout the U.S., which resulted in many hospitalizations and deaths. Coordinated response efforts had to be taken by the U.S. government to stop the spread of the virus.

H1N1 is spread from person-to-person the same way in which seasonal flu is spread. The H1N1 flu is not spread by eating pork or pork products.

This year, the 2010-2011 flu vaccine will include protection against the H1N1 virus strain.
