- Latest surveillance reports hospital test positivity at 11.9% and admissions at 3.9 per 100,000, levels typically reached closer to December.
- UKHSA confirms a genetically drifted A(H3N2) subclade K is now the predominant strain driving the unusually rapid ascent of cases.
- Early estimates indicate flu vaccines provide about 70–75% protection against hospitalisation in children and roughly 30–40% in adults.
- Health authorities are issuing urgent vaccine calls for eligible groups and expanding access through GP surgeries, pharmacies, community clinics and school programmes.
- NHS leaders are preparing for mounting pressure on services as infections remain highest in children and rise in older adults, with scientists estimating a higher R value near 1.4.
