For the first time, influenza A(H1N2)v has been discovered in a human in the United Kingdom.
Swine flu has been detected in pigs in the UK, according to the UK Health Security Agency (UKHSA).
The case was discovered as part of the UKHSA’s routine nationwide flu surveillance.
It was discovered after the person having respiratory symptoms was tested by their doctor.
The UKHSA said: “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 patient experienced mild symptoms and has now recovered.
The source of their infection is not yet known and an investigation is currently underway.
Chief veterinary officer Christine Middlemiss added: “We know that some diseases of animals can be transferred to humans – which is why high standards of animal health, welfare and biosecurity are so important.
“Through our animal and human surveillance systems, we work together to protect everyone.
“In this case we are providing specialist veterinary and scientific knowledge to support the UKHSA investigation. Pig keepers must also report any suspicion of swine flu in their herds to their local vet immediately.”
H1N1, H1N2, and H3N2 are swine influenza virus subtypes that are commonly seen in pigs.
Those having respiratory symptoms are advised to follow existing recommendations, which include avoiding contact with others.
They can occasionally impact humans, and this usually occurs after direct or indirect contact with pigs or exposure to a contaminated environment, according to the UKHSA.
