UK identifies first human case of H1N2 swine flu strain

London: Health authorities in the UK have confirmed the occurrence of the first human case of a swine flu strain akin to the one prevalent in pigs.

The UK Health Security Agency (UKHSA) announced the detection of the H1N2 variant in an individual who had undergone testing upon exhibiting respiratory symptoms.

This particular strain of the H1N2 virus, not previously identified in humans within the country, has similarities to viruses found in pigs, according to Meera Chand, the incident director at the agency. Chand emphasised the agency's swift efforts to trace close contacts and mitigate potential transmission.

The affected individual experienced a mild illness and has since fully recovered, as stated by the UKHSA. However, investigations into the source of the infection are ongoing, with the origin remaining undetermined.

UKHSA's chief veterinary officer, Christine Middlemiss, highlighted the provision of veterinary and scientific insights to support the ongoing investigation.

Swine influenza A viruses, particularly H1N1, H1N2, and H3N2, are prevalent in pig populations across various regions globally. While primarily affecting pigs, these viruses sporadically transmit to humans, often through direct or indirect contact with infected pigs or contaminated environments.

The H1N1 pandemic in 2009 marked a significant influenza outbreak, initially reporting an official death toll of 18,500. However, subsequent revisions by The Lancet medical journal indicated a broader fatality range between 151,700 and 575,400 deaths.
