NHS Braces for 'Tidal Wave' of Mutant Flu

This winter's flu season is anticipated to be exceptionally severe, with a new H3N2 strain raising significant concerns among health authorities. This mutated 'K' strain is described as more infectious and potentially more dangerous than typical influenza viruses, leading to predictions of a substantial surge in cases.

Early indications suggest a considerable number of infections, with a government study revealing that the 'K' strain was prevalent in the majority of diagnosed flu cases. The potential for widespread illness is already prompting discussions about reintroducing public health measures, such as mask-wearing in healthcare settings.

The impact of this outbreak is compounded by reduced herd immunity, as the population has not experienced a widespread flu season since 2022. This vulnerability means the NHS is preparing for a significant increase in demand, potentially straining resources as the 'tidal wave' of illness approaches.
