For the H1N1/09 virus strain responsible for the 2009 flu pandemic, see Pandemic H1N1/09 virus. For the 1918 influenza A(H1N1) pandemic, see 1918 flu pandemic. Influenza A (H1N1) virus is the subtype of influenza A virus that was the most common cause of human influenza (flu) in 2009.It is an orthomyxovirus that contains the glycoproteins haemagglutinin and neuraminidase.1N1 strains caused a small percentage of all human flu infections in 2004â2005. Other strains of H1N1 are endemic in pigs (swine influenza) and in birds (avian influenza). In June 2009, the World Health Organization (WHO) declared the new strain of swine-origin H1N1 as a pandemic.
