For the H1N1/09 virus strain responsible for the 2009 flu pandemic, see Pandemic H1N1/09 virus. For the current pandemic of Influenza A(H1N1), see 2009 flu pandemic. For the 1918 pandemic of Influenza A(H1N1), see 1918 flu pandemic.
Influenza A (H1N1) virus is a subtype of influenza A virus and the most common cause of influenza (flu) in humans. Some strains of H1N1 are endemic in humans and cause a small fraction of all influenza-like illness and a small fraction of all seasonal influenza. H1N1 strains caused a few percent of all human flu infections in 2004–2005.[1] Other strains of H1N1 are endemic in pigs (swine influenza) and in birds (avian influenza).
In June 2009, the World Health Organization declared the new strain of swine-origin H1N1 as a pandemic. This strain is often called swine flu by the public media.
