H1N2 is a subtype of the influenza A virus, which is also referred to as bird flu. Influenza H1N2 can infect both human and pig. H1N2 reassortant viruses between H1N1 and H3N2 human viruses appeared in 2001 and became established, circulating viruses until 2004. Lately, H1N2 has been reported that infected human in Netherlands in 2018 and in Sweden in 2019. It is a reassortant of human seasonal flu viruses containing the same hemagglutinin "H1" gene as circulating seasonal A (H1N1) pdm09 viruses and the same neuraminidase "N2" gene as circulating seasonal A(H3N2) viruses.
