Influenza A virus subtype H1N2 (A/H1N2) is a subtype of the species Influenza A virus (sometimes called bird flu or swine flu). It is currently endemic in pig populations and is occasionally seen in humans.

在 2002年 2月6日在日内瓦的世界卫生组织和英国的公共卫生研究所确认在英国、以色列和埃及同样出现了人类甲型 (H1N2)。 2001年至2002年的A（H1N2）威斯康星毒株被认为可能是由于最近流行的H1N1和H3N2的基因重配。

The A (H3N2)v and A (H1N2)v viruses contained the matrix protein from the A (H1N1)pdm09 virus, raising the possibility of increased transmissibility among humans and underscoring the potential for influenza pandemics of novel swine-origin viruses. We report on the differing histories of A (H1N2) viruses among humans and animals.

2005年10月31日 · Currently circulating influenza A viruses are of H1N1 and H3N2 subtypes. Circulating influenza B viruses belong to one of two lineages: B/Yamagata and B/Victoria. Then, in 1957, a new influenza virus suddenly appeared in Southeast China.

2023年2月25日 · H1N2 is a subtype of the influenza A virus, which is also referred to as bird flu. H1N2 currently poses a tremendous public health concern because it has spread to both human and pig populations.

2024年6月13日 · The α-swH1N2 virus replicates efficiently in human airway cultures and exhibits phenotypic signatures similar to the human H1N1 pandemic strain from 2009 (H1N1pdm09).

On 4 August 2023, the United States IHR National Focal Point informed PAHO/WHO of a human infection with a novel influenza A (H1N2) variant virus identified in the State of Michigan and confirmed by the US CDC.

2025年3月21日 · Explore the H1N2 virus, its impact on swine and humans, transmission patterns, genetic variations, and diagnostic approaches for monitoring potential risks.

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.

2023年12月1日 · When an influenza virus that normally circulates in swine is detected in a person, it is called a “variant influenza virus”. A (H1N1), A (H1N2) and A (H3N2) are major subtypes of influenza viruses circulating in pigs and occasionally infect humans.
