Novel reassortant influenza A(H1N2) virus derived from A(H1N1)pdm09 virus isolated from swine, Japan, 2012

Emerg Infect Dis. 2013 Dec;19(12):1972-4. doi: 10.3201/eid1912.120944.

Abstract

We isolated a novel influenza virus A(H1N2) strain from a pig on January 13, 2012, in Gunma Prefecture, Japan. Phylogenetic analysis showed that the strain was a novel type of double-reassortant virus derived from the swine influenza virus strains H1N1pdm09 and H1N2, which were prevalent in Gunma at that time.

Keywords: H1N1 subtype; Swine; influenza A (H1N2); reassortant viruses; virus.
