Part Description

LP94776-9   Influenza virus A H1 2009 pandemic
An influenza virus that had never been identified as a cause of infections in people before the 2009 H1N1 (Swine flu) pandemic. Genetic analyses of this virus showed that it originated from animal influenza viruses and was unrelated to the human seasonal H1N1 viruses that had been in general circulation among people since 1977. Antibodies to the seasonal H1N1 virus did not protect against the pandemic H1N1 virus, however a significant percentage of people age 65 and older had some immunity against the pandemic virus. After early outbreaks in North America in April 2009 the new influenza virus spread rapidly around the world. Unlike typical seasonal flu patterns, the new virus caused high levels of summer infections in the northern hemisphere, and then even higher levels of activity during cooler months. The virus also led to patterns of death and illness not normally seen in influenza infections. Most of the deaths occurred among younger people, including those who were otherwise healthy.
