The first detection of the flu that's been circulating in pigs in the UK has been found in a person. 

The government has confirmed, Influenza A(H1N2)v, a virus similar to the virus circulating among pigs in the UK has been found in the UK - with reports that the person affected is from Yorkshire

The patient was tested by their GP in North Yorkshire after experiencing respiratory symptoms. The strain was identified via polymerase chain reaction (PCR) testing and genome sequencing.

As usual in emerging infection events, the UK Health Security Agency (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.

UKHSA is monitoring the situation closely and is taking steps to increase surveillance within existing programmes involving GP surgeries and hospitals in parts of North Yorkshire. To assist in the detection of cases and assessment of transmission, those people who are contacted and asked to test are encouraged to do so.

Meera Chand, Incident Director at UKHSA, said: "It is thanks to routine flu surveillance and genome sequencing that we have been able to detect this virus. This is the first time we have detected this virus in humans in the UK, though it is very similar to viruses that have been detected in pigs.

"We are working rapidly to trace close contacts and reduce any potential spread. In accordance with established protocols, investigations are underway to learn how the individual acquired the infection and to assess whether there are any further associated cases."
