Influenza A virus subtype H1N2
The virus does not cause more severe illness than other influenza viruses, and no unusual increases in influenza activity have been associated with it.
A(H1N2) was identified during the 2001–02 flu season (northern hemisphere) in Canada, the U.S., Ireland, Latvia, France, Romania, Oman, India, Malaysia, and Singapore with earliest documented outbreak of the virus occurring in India on May 31, 2001.
On February 6, 2002, the World Health Organization (WHO) in Geneva and the Public Health Laboratory Service (PHLS) in the United Kingdom reported the identification influenza A(H1N2) virus from humans in the UK, Israel, and Egypt.
Because the hemagglutinin protein of the virus is similar to that of the currently[when?] circulating A(H1N1) viruses and the neuraminidase protein is similar to that of the current A(H3N2) viruses, the seasonal flu vaccine should provide good protection against influenza virus as well as protection against the currently circulating seasonal A(H1N1), A(H3N2), and B viruses.
New case of H1N2 was found on a Minnesota baby in December 2011.
