A surge in H3N2 flu cases has hospitalized thousands of UK children, straining the NHS, though experts say it's a typical seasonal spike, not a new threat.

A surge in flu cases among UK children, driven by the long-circulating Influenza A/H3N2 strain, has led to thousands of hospitalizations and significant strain on the NHS, described by officials as a worst-case scenario. While some officials label it an "unprecedented wave" or "superflu," Oxford University’s James Hay clarifies that the outbreak’s spread and severity align with typical flu season patterns. The H3N2 strain, known for causing more severe illness in children and older adults, recurs periodically, leading to intense but expected spikes. Experts stress the situation does not indicate a new or more dangerous virus, urging vaccination, hygiene, and staying home when sick to reduce transmission and protect healthcare systems.
