On Monday, UK public health officials announced the confirmation of the first human case of a swine flu strain closely resembling one found in pigs. The UK Health Security Agency (UKHSA) verified the H1N2 virus variant in an individual who underwent testing for respiratory symptoms as directed by their doctor. This particular strain has not been previously identified in humans within the country.

“This marks the inaugural identification of this virus in humans in the UK, although its resemblance to viruses found in pigs is evident,” stated Meera Chand, the agency’s incident director. “We are swiftly tracing close contacts and implementing measures to minimize any potential spread.”

The affected individual experienced a mild illness and has fully recovered, as per the agency’s statement. However, the source of their infection remains undetermined and is currently under investigation.

Christine Middlemiss, Chief Veterinary Officer at UKHSA, highlighted that veterinary and scientific expertise is actively supporting the ongoing investigation.

Influenza A(H1) viruses are prevalent in swine populations globally. The H1N1, H1N2, and H3N2 viruses represent key subtypes of swine influenza A viruses in pigs.

These viruses can sporadically infect humans, typically following direct or indirect exposure to pigs or exposure to contaminated environments.

The H1N1 pandemic in 2009 represented the initial significant influenza outbreak in the 21st century.
