How is the 2009 H1N1 flu (swine flu) different than the “regular” flu?
• The 2009 H1N1 virus does not appear to be more severe than seasonal flu. • Unlike seasonal flu, which tends to cause more significant illness in elderly people and very young children, H1N1 flu (swine flu) is most common in people 5 to 24 years old. • While seasonal flu usually peaks in January or February, the 2009 H1N1 virus has caused illness during the spring summer months and remained active into the fall.
