UKHSA Detects First Human Case of Influenza A(H1N2)v: Understanding the Risks and Implications
On November 27, 2023, the UK Health Security Agency (UKHSA) announced the detection of the first human case of influenza A(H1N2)v, a variant of influenza A virus that typically circulates in pigs. This discovery raises concerns about the potential for interspecies transmission and its implications for human health. Overview of Influenza A(H1N2)v Influenza A(H1N2)v, also known as swine flu, is a respiratory virus that primarily affects pigs. However, occasional spillover infections can occur when humans come into close contact with infected pigs or contaminated environments. While sporadic human cases of influenza A(H1N2)v have been reported globally, this is the first instance identified in the UK.
