A new strain of swine flu, influenza A(H1N2)v, has been detected in a human in the UK for the first time. The patient, who had not worked with pigs, visited their GP in North Yorkshire with breathing problems and has since fully recovered. The source of the infection remains unknown. The UK Health Security Agency (UKHSA) is closely monitoring the situation and enhancing surveillance in GP surgeries and hospitals. Globally, there have been fifty cases of this strain since 2005, but the UK case is genetically distinct. This strain is similar to those found in pigs but differs from recent human cases of H1N2 elsewhere. The incident has prompted a collaborative effort between the UKHSA and veterinary authorities to investigate and protect public health. Although this case does not immediately suggest a pandemic risk, it raises concerns as zoonotic diseases have historically led to pandemics. Authorities are tracing contacts and urging pig keepers to report any signs of swine flu.
