The UK Health Security Agency (UKHSA) has detected a single confirmed human case of influenza A(H1N2)v.
Influenza A(H1N2)v is similar to flu viruses currently circulating in pigs in the UK. This is the first detection of this strain of flu in a human in the UK.
As is usual early in emerging infection events, UKHSA is working closely with partners to determine the characteristics of the pathogen and assess the risk to human health.
The case was detected as part of routine national flu surveillance undertaken by UKHSA and the Royal College of General Practitioners (RCGP). The individual was tested by their GP after experiencing respiratory symptoms. Influenza A(H1N2)v virus was detected by UKHSA using polymerase chain reaction (PCR) testing and characterised using genome sequencing.
The individual concerned experienced a mild illness and has fully recovered. The source of their infection has not yet been ascertained and remains under investigation.
Close contacts of the case are being followed up by UKHSA and partner organisations. Any contacts will be offered testing as necessary and advised on any necessary further care if they have symptoms or test positive.
