The H1N1 virus -- sometimes called swine flu -- surfaced in the
United States in 2009, causing the first global pandemic in more than 40
years and resulting in a number of hospitalizations and deaths, according to
the Centers for Disease Control and Prevention.
The public is advised to get yearly flu vaccinations to protect
against H1N1 as well as other types of flu viruses.
